So I have two strings '5' and '12'. In Ruby (ruby 2.0.0p598 (2014-11-13 revision 48408)) I want to do a comparison on these two to see which is less than the other. If I do '5' <= '12' I get false as a result. Why?

How to limit concerns in routing to certain actions for root but not for namespace - Rails 4
So lets consider the following in routes.rb
concern :shared_actions do
resources :courses do
resources :lessons
end
resources :users
end
my admin namespace has the following
namespace :admin do
concerns :shared_actions
get '', to:'dashboard#index', as: '/'
resources :lessons
end
and my root path '/' also shares the same concerns using
concerns :shared_actions
So what i want is,for the root path i want only index and show action for the courses path but in the admin namespace i want to have all actions for courses.
Is there a way to do that without writing explicit code for each case?
Integrating FB Page with Rails
I'm trying to integrate FB page with my new Rails application.
Problems:
-
The Fb Page container is properly rendered only when request is directly from addressbar of client(putting url in addressbar and hit go) OR when request is from one controller to other.
-
When any action of same controller is clicked on website i.e. call from SAME controller, the FB Page block is not rendered properly.
Test it here : Test Link
What I've done is:
- Added FB JS in application.html.erb
- And there itself, I'm putting my code for Fb Page.(shown below)
application.html.erb
<!DOCTYPE html>

has_many :through how it works?
First of all let me say that I come from oldschool php framework and outdated practices that I'm struggling to undo them. When the PHP I found situations N-N I simply created a new table and was 1-N relationship with this new table. Example:
tbl_users
tbl_posts
Relationship:
tbl_users N-N tbl_posts
So I just created in the new table and made 1-N relationship (common has_many). Example:
tbl_users 1-N tbl_like_posts
tbl_posts 1-N tbl_like_posts
I do not know if there was something equivalent and I did not use because I was never charged. But the reality is that I've looked on the has_many: through and fail to make it into my head. Why can I not do what I did before? What: through is special? What it will ease me? I even understand how to use, but did not understand why to use.
I'm sorry if the question was kind of silly, but I'm trying to drop PHP addictions and learn the rails correctly.
Rails Users updating information in custom routes?
Not sure how to title my question...
My intent is that users will have a list of items (and only the current_user can edit this list)
class Item < ActiveRecord::Base
belongs_to :user
end
class User < ActiveRecord::Base
has_many :items
end
I have a Users controller (note: I'm also using devise gem, but created a separate Users Controller)
class UsersController < ApplicationController
load_and_authorize_resource
def show
@user = User.find(params[:id])
end
def list
@user.items.build
end
private
def set_user
@user = User.find(params[:id])
end
def user_params
params.require(:user).permit(
items_attributes: [:user_id, :item, :name, :_destroy]).merge(user_id: current_user.id)
end
end
Right now I have set up routing
get 'users/:id/list', to: 'users#list', as: :list
Which gives me this: localhost:3000/users/1/list
Theoretically, this should be the show view... where it'll populate the list of items for user id: 1.
I want to be able to do localhost:3000/list/edit So the user can update this list.
My form in views/users/list.html.erb (I'm using cocoon gem for help with nested forms).
<%= simple_form_for @user do |f| %>
<%= f.simple_fields_for :items do |i| %>
<%= f.text_field :item %>
<%= f.text_field :name %>
<% end%>
<%= link_to_add_association 'add item', f, :items %>
<%= f.button :submit %>
<% end %>
I know my form is in my list.html.erb where it'll populate all the items, but I'm just doing this for testing purposes.
How do I update the form to save into items database and its associated with the current user?
Rails flash message not showing up
I'm trying to verify a DEA number by calling an action that calls a verify gem.
Here's the view
<label for="prescriber_dea_number">DEA number</label>
<%= text_field_tag :prescriber_dea_number %>
<%= link_to "Verify DEA number", dea_verification_insight_reports_prescriber_activity_with_patient_request_index_path remote:true %>
Here's the controller action
def dea_verification
dea = params[:prescriber_dea_number]
respond_to do |format|
if PmpCheckdigit.dea_number?(dea)
#flash confirmation
flash[:notice] = "DEA number is valid"
format.js
else
#flash error
flash[:error] = "DEA number is invalid, Expected something similar to 'AB12345678'"
format.js
end
end
end
When the button to Verify is clicked, no flash message appears on the page
Here's what I get in the log

How to customize version filename in Carrierwave?
I have a strange issue. I am trying to use master branch of carrierwave with Rails 3.2.xx project. I need to customize filenames of the versions. But when I add full_filename method in the version block, my original file also gets reduced to the dimensions specified for version.
When I remove full_filename method, it all works as expected, but thumb filename has thumb_ prefix which I don't want.
Is there a new way to customize version filenames. I have been using this way successfully in 0.10.0 and before.
Below is my uploader. This is a generated uploader with store_dir overrides.
class TestUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
# storage :file
storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Create different versions of your uploaded files:
version :thumb do
process :resize_to_fit => [200, 200]
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}/#{version_name}"
end
def full_filename(for_file = model.logo.file)
super(for_file).sub(version_name.to_s + '_', '')
end
end
end
Any ideas? All I need to do is to remove version_name part from its filename, since I am saving the versions in separate folders. I searched through Wiki and internet, but couldn't find a new way of doing this.

How to have same routes with and without namespace - rails 4
So, i am making a custom admin panel in the admin namespace.
and i have a resources courses in it.
what i don't know is how can i have the same routes shared between the namespace and without the namespace
eg: localhost:3000/admin/courses & localhost:3000/courses
the controllers ok can be different
the thought is that its not really DRY paradigm if i have both resources for the same route
namespace admin do
resources :courses
end
and just
resources :courses
Is there a way to have one resource and be shared between namespace and without namespace or the example above is the way to go?

How to share image on Facebook using fb_graph gem in rails
I want to share image on Facebook using fb_graph gem but i don't understand the exact procedure that how to implement in localhot.
I not use "localhost:3000" but i used "lvh.me:3000" because in my application i used subdomain concept so when user login then url is change to "xyz.lvh.me:3000/"
in my controller :-
class FbShareController < ApplicationController
def auth
@album = current_photographer.albums.friendly.find(params[:album_id])
@album_photo = @album.album_photos.friendly.find(params[:photo_id])
cookies["title"] = { :value => @album_photo.photo_title, :expires => 1.minute.from_now }
cookies["url"] = { :value => @album_photo.photo.url(:original), :expires => 1.minute.from_now }
@client = client
redirect_to @client.authorization_uri(
:scope => [ :user_photos, :publish_pages, :user_posts]
)
end
def callback
# @album = current_photographer.albums.friendly.find(params[:album_id])
@client = client
@client.authorization_code = params[:code]
access_token = @client.access_token! :client_auth_body # => Rack::OAuth2::AccessToken
me = FbGraph::User.me(access_token)
title = cookies["title"]
url = cookies["url"]
me.feed!(
:message => title,
:link => url,
:name => title,
:picture => url
)
redirect_to album_path(@album)
end
private
def client
if Rails.env.development?
key = "xxxxxxxxxxxxxxx"
secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
else
key = "xxxxxxxxxxxxxxx"
secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
end
fb_auth = FbGraph::Auth.new(key, secret)
client = fb_auth.client
client.redirect_uri = "http://#{request.host_with_port}/fb_share/callback"
client
end
end
I create app on my Facebook named lvh.me:3000 and Facebook provide me two IDs like User id and App id and also provide App secret key.
So which combination i have to use in my controller ?
fb_auth = FbGraph::Auth.new(User_id, secret) OR
fb_auth = FbGraph::Auth.new(App_id, secret)
However, i already used both combination but i get following error:-
{
"error": {
"message": "Error validating application. Cannot get application info due to a system error.",
"type": "OAuthException",
"code": 101
}
}
Whats wrong with my code i don't know.
I don't know that how to set configuration in facebook for this.
I need step by step solution if any one have because i am totally new in rails.
Any one have proper solution or steps because i already spent much more time behind this but i have no idea what to do.
Thanks in advance.
Ruby on Rails persistently store Hash from CSV
I have a ruby script written which takes a CSV file and converts the input into a hash:
Culper = File.open('.\CulperCSV.csv')
culper_hash = {}
# set up culper code hash from provided CSV
CSV.foreach(Culper) do |row|
number, word = row
culper_hash[word] = number
end
and I am trying to make a Rails app using the script.
My question: How do I store the Hash persistently (or the CSV data so I can build the hash) so that I can minimize load times?
My thoughts:
1) Load the CSV data into a database (seed it) and each time I get a visitor on my site, do the above assignment into a hash but from the db. (not sure how to do this but I can research it).
or
2) Load the complete hash into the database (I think I would have to serialize it?) so that I can do just one fetch from the db and have the hash ready to go.
I am very new to building apps, especially in Rails so please ask questions if what I am trying to do doesn't make sense.

change type in polymorphic association in rails
I am new to rails and I'm using rails Polymorphic association and I ran into a problem I have two models EmployeeTable and ProductTable. Both have some picture in Picture Model
class Picture < ActiveRecord::Base
belongs_to :imageable, polymorphic: true
end
class EmployeeTable < ActiveRecord::Base
has_many :pictures, as: :imageable
end
class ProductTable < ActiveRecord::Base
has_many :pictures, as: :imageable
end
there are two column in Picture imagable_id and imagable_type. When I create an entry in table it stores imagable_type as either "EmployeeTable" or "ProductTable". Can I change these name to any different Names like "employee" and "product".
Thanks in advance

What could be possible test cases for this controller action and how can i handle if else conditions. Using minitest framework in RubyonRails
I am new to writing test cases and I cant figure out the scenarios of writing tests. For example there are too many if else conditions in controller how would I write cases for these conditions. Below is my registration controller. I am using rails minitest framework for rails 3.2.1 version.

Using SendCloud with 'X-SMTPAPI' in Rails
I hope this post will help someone.I need to use SendCloud to send emails through smtp.At the begin i add header in ActionMailer:
headers["X-SMTPAPI"] = JSON.dump({"to" => emails, "sub" => {"%name%" => names}})
But it can't work, and i also can't receiver the return error code through Rails.Then i find the way through communication with their support:
headers["X-SMTPAPI"] = Base64.encode64(JSON.dump({"to" => emails, "sub" => {"%name%" => names}}))
But it also can't work correctly.Then i compare the generated headers["X-SMTPAPI"] with the sent headers["X-SMTPAPI"], and found Rails insert '\n' in it for format.In the end, Mail gem convert the '\n':
def encode_crlf(value)
value.gsub!(CR, CR_ENCODED)
value.gsub!(LF, LF_ENCODED)
value
end
So, if i want it's success, i need to do like this:
headers["X-SMTPAPI"] = Base64.encode64(JSON.dump({"to" => emails, "sub" => {"%name%" => names}})).gsub!(/\n/,'')
Wow, i can send 'x-smtpapi' header in Rails successfully!

How to check rails params hash from url query parameter contains double quoted string?
I created a GET endpoint to serve an API using rails. I want to be able to check for when the user passes double quotes for the query parameter in the url.
So for example the user could call the below endpoint by passing the query parameter with double quotes or no quotes. My application is expected to behave differently if the double quotes are found in the query params..
localhost:8080/company/data.json?q="America Online in UK"&size=10
Now the user can also call the endpoint with no double quotes like this:
localhost:8080/company/data.json?q=America+Online+in+UK&size=10
OR
localhost:8080/company/data.json?q=AOL&size=10
How do I handle the above use-cases in a rails controller with respect to spaces and double quotes?
Ruby on Rails 3: Streaming data and catching exception
I'm streaming data using the following approach:
self.response_body = Enumerator.new do |y|
10_000_000.times do |i|
y << "This is line #{i}\n"
end
end
I'm trying to catch any exception generated inside Enumerator and present something nicer to the user. Right now, the app is presenting an ugly error page from Torquebox. e.g.
I tried rescue and redirect_to and many other ways to catch the exception (including add a middleware class for handling exceptions). Any help would be appreciated!.
(The app is made under jruby v1.7.19 and torquebox v3.1.1)
Use same routing for subdomain as for simple domain request

Firefox drop down menu not showing current setting
TL;DR A drop down menu is always showing the same selection (before opening the menu) for Firefox alone. Other browsers show the current saved setting, but Firefox does not.
I have a settings page where users can choose their timezones. The user opens the drop down menu and selects their time zone, then clicks the button "Apply"
When the user does this, the page is reloaded, and the (previously saved) timezone shows as the selection for the drop down menu.
So the steps to updating your timezone go like this
- Dropdown menu shows "UCT"
- Open the drop down menu and select "Eastern Time"
- Click Apply
- Page reloads and drop down shows "Eastern Time" for all browsers other than Firefox
Is this a Firefox bug? I've turned off accelerating graphics, but this didn't resolve the issue.
i am migrating an application from rails 2.3 to rails 3.1, most of it is done but there is a issue, when the session get expired and i reload the page instead of redirecting me to login page i am getting a error
undefined method `size' for ActionDispatch::Cookies::CookieJar:0x007fa415c12670>
here is the code where i am getting the error
def access_denied
respond_to do |accepts|
accepts.html do
test_location
if cookies.size==0 && request.host == "somedomain.com"
redirect_to "/cookies_disabled.html"
else
redirect_to new_session_url
end
end
accepts.js do
render :text => "window.location.href = '#{new_session_url}';"
end
end
false
end
any help will be appriciated, Thanks.

before_create is not called on model.create
I have thiw code:

def generate_permalink
binding.pry
self.permalink = "123456789"
end
end
When I call in ProjectsController#create
p = Project.new
p.name = "abcdef"
p.save
App doesn't stop on binding.pry in generate_permalink, and the project is not valid and is not saved because permalink == nil. Why generate_permalink method is not called?
Thanks
Migration to add enum column in rails3 and enumerated_attribute
I need a migration to add column of type enum in rails 3. I will be using enumerated_attribute gem.
I generated a migration to add the column:
rails generate migration addUsage_reports_accessToClientParam usage_reports_access:enum
Now I need to set up the values for the enum and set the default value. Here is the generated migration:
class AddUsageReportsAccessToClientParam < ActiveRecord::Migration
def self.up
add_column :client_params, :usage_reports_access, :enum
end
def self.down
remove_column :client_params, :usage_reports_access
end
end
Thanks
Rails Engines: How to generate a controller for Rails engine?
We have three Rails engines maintained in a single application. They are placed in vendor folder,
vendor/
- Engine1
- Engine2
- Engine3
How can I generate controller for Engine1 from my root folder as we normally create controllers? For example,
> rails generate controller Engine1:users
Note:- I could create controller by moving around the folders. That is move to Engine1 folder from root app and generate controller, which works fine. But every time moving around from my root app and generating gets bit hard.
How to properly mix in a Rails helper
I'm trying to add some custom behavior to I18n. Since we want this behavior to be performed in I18n itself as well as the Rails TranslationHelper before their respective translate methods, I've created the following module in lib/translate_extension.rb:
module TranslateExtention
def new_translate(*args)
...
translate(...)
end
end
In config/initializers/i18n.rb the following is working:
module I18n
extend TranslateExtention
end
However I'm having trouble getting it added as a helper. The following in config/initializers/translation_helper.rb is not doing the trick:
module ActionView
module Helpers
module TranslationHelper
include TranslateExtention
end
end
end
I keep getting told that new_translate is not defined for my views.
This is being done on Rails 3.2.22
Rails: is twitter typeahead conflicts client side validation?
I am using client side validation(v3.0.13) gem in my rails(v3.0.20) app. Recently I added twitter's typeahead.js(v0.10.2) for auto suggest.
I have a model named Insurance and the column 'name' is mandatory. When I submit a form with these two js files loaded, I get javascript error Cannot read property 'presence' of undefined in browser console. After this error, other javascript code is failed to run, for example If I put a alert in form submit function, its not working.
Model
insurance.rb
class Insurance < ActiveRecord::Base
validates :name, :presence => { :message => "Must be filled" }
end
form.html.erb
<%= javascript_include_tag "rails.validations", "typeahead" %>
<%= stylesheet_link_tag "typeahead"%>
<%= form_for @insurance, :validate => true, :html => {:id => 'insurance_form', :class=>"form-horizontal"} do |f| %>
<div class="control-group">
<%= f.label :name, :class=>"control-label" %>
<div class="controls">
<%= f.text_field :name, :class =>"input-medium typeahead" %>
</div>
</div>
...
<% end %>
And my javascript code
var insurance_names = ["aaa", "bbb", "ccc"];
var substringMatcher = function(strs) {
return function findMatches(q, cb) {
var matches, substringRegex;
matches = [];
substrRegex = new RegExp(q, 'i');
$.each(strs, function(i, str) {
if (substrRegex.test(str)) {
matches.push({ value: str });
}
});
cb(matches);
};
};
$('.typeahead').typeahead({
hint: true,
highlight: true,
minLength: 1
},
{
name: 'insurance_names',
source: substringMatcher(insurance_names)
}).on('typeahead:selected', function($e, datum){
$(this).trigger('change');
});
If I comment the model validation code and then submit the form, then there is no javascript error. And also without this typeahead.js client side validation is working fine.
Can anyone help me to solve this problem?

RSpec for a rails controller
I am new to ROR and RSpec. I have written a controller that updates staff for a student like below:
class EStudentsController < ApplicationController def allot @staff= Staff.find(params[:staff_id]) @student= Student.find(@staff.staff_id) @estaffforstudent= EStaffStudent.find(params[:student_id]) @estaffforstudent.staff_id = @staff.id @estaffforstudent.save redirect_to [@student, @staff] end
How do I write RSpec for the above? Some examples with study resources will be helpful.
Thanks for the help.

File deleted each time
I have a ruby controller
def new
counter = 1
fileW = File.new("query_output.txt", "w")
file = File.new("query_data.txt", "r")
while (line = file.gets)
puts "#{counter}: #{line}"
query = "select name,highway from planet_osm_line where name ilike '" +line+"'"
@output = PlanetOsmLine.connection.execute(query)
@output.each do |output|
fileW.write(output['highway'] + "\n")
end
counter = counter + 1
end
file.close
query = ""
@output = PlanetOsmLine.connection.execute(query)
end
So in this I am reading from a file like
%12th%main%
%100 feet%
%12th%main%
%12th%main%
%12th%main%
%100 feet%
In the ruby console I can see all the queries getting executed but in query_output.txt I only get the output of last query. What am I doing wrong here?

Fetch Data From Multiple Models In One View
This seems easy but I can't figure out how to do it
I'm trying to implement Ransack search in my rails app and for that I have a generated a model Cofounder which don't have any fields in it and I have association between Cofounder and CustomUser model which has email and other fields but i only want to search through email using ransack, i have this association between these two:
has_many :cofounders
belongs_to :CustomUser
(Do i need to have id if Yes how do i do it)
CoFounder Model
class Cofounder < ActiveRecord::Base
belongs_to :CustomUser
end
CofoundersController
class CofoundersController < ApplicationController
layout "custom_layout", only: [:index]
def index
@q = Cofounder.ransack(params[:q])
@cofounders = @q.result
@cofoundes = CustomUser.all
@countries = Country.all
end
end
and in my index view
<% search_form_for @q, url: cofounders_index_path do |f| %>
<%= f.search_field :email_cont, placeholder: "Search Here" %>
<%= f.submit "Search" %>
<% end %>
<%= select_tag "search_by_country", options_for_select(@countries.collect{|x| [x.name]} , params[:search_by_country] ),{prompt: "Select country"} %><br><br>
<%= select_tag "choose_a_role", options_for_select(@cofoundes.collect{|x| [x.first_name]} , params[:choose_a_role] ),{prompt: "Choose A Role", id: "select", multiple: true} %><br><br>
<% @cofoundes.each do |cofounder| %>
<%= cofounder.email %>
<%end%>
it is giving me error code
undefined method `email_cont' for #
i know email_cont if not a field in cofounder and i'm accessing that field in cofounder which is giving me error, how do i get those values in cofounder for successful Ransack search.
any help would be appreciated :)

Error when installing devise- i am a novice
I have installed rails and am running the Git Bash and am on windows 7 64 bit, i have installed gemfile and updated and this is my first use of ruby! I am following the instrustions from devise's github http://ift.tt/LkuK7q . I am probably being very stupid but when i run gem 'devise' and this error occurs:
ERROR: while executing gem... <Gem::commandlinerror> unknown command /devise
Any help would be greatly appreciated

how to test rails custom validation
I have a custom validation that checks whether a param is valid JSON or not:
def is_valid_json
begin
!!JSON.parse(preferences)
rescue
errors.add(:preferences, "This is not valid JSON")
end
end
In my controller test, I want to make sure that when I send in a bad value, the status code of the response is 422. Here is the spec from my controller:
it 'should return a 422 when validations fail' do
put :update, {:user_preferences => { :email => @email, :preferences => 'badval' } }
expect(response.status).to eq(422)
res = JSON.parse(response.body)
expect(res['error']).to_not be_blank
end
The test fails due to an error:
Failure/Error: put :update, {:user_preferences => { :email => @email, :preferences => 'badval' } }
ActiveRecord::RecordInvalid:
Validation failed: Preferences This is not valid JSON
Controller code:
def update
@user_preference = UserPreference.where(email: params[:user_preferences][:email]).first
authorize! :update, @user_preference
@user_preference.update_attributes!(params[:user_preferences])
render_api_response(@user_preference)
end
When I make the request from the browser, I get a 422 return status code, so is there a reason that I can't get the same result from the test?
Rails delete table row via migration
I'm trying to delete several rows in the table actionable_items via the following migration. I have debugged and can confirm that the variables that store the table row are not nil. The migration runs successfully, but it doesn't delete the row from the table. Also, does anyone know why I can debug a migration when I run rake db:migrate:redo but not when I run rake db:migrate ?
class RemoveActionableItems < ActiveRecord::Migration
class ActionableItem < ActiveRecord::Base
attr_accessible :actionable_item, :name, :sequence, :type
end
class MenuItemTEMP < ActionableItem
self.table_name = "actionable_items"
end
class InsightReportMenuItemTEMP < ActionableItem
self.table_name = "actionable_items"
end
def up
validation_settings = MenuItem.find_by_name("Validation Settings")
identifier_lookup = MenuItem.find_by_name("Identifier Lookup")
compliance = InsightReportMenuItem.find_by_name("Compliance")
debugger
validation_settings.destroy! #unless validation_settings.nil?
identifier_lookup.destroy! #unless identifier_lookup.nil?
compliance.destroy! #unless compliance.nil?
end
def down
MenuItem.create :name => "Validation Settings", :type => "MenuItem"
MenuItem.create :name => "Identifier Lookup", :type => "MenuItem"
InsightReportMenuItem.create :name => "Compliance", :type => "InsightReportMenuItem"
end
end
I also tried deleting from the rails console, but once again, pgAdmin is showing the row not deleted.

cannot get /admin for Activeadmin
I have an existing app with Rails 3.2.17 and angular js. I would like to include Activeadmin in the existing app.
I followed the steps from active-admin post from ryan bates. I performed following processes:
- Added
gem activeadminin Gemfile - Run
bundle install rails g active_admin:install --skip-users(as I already have devise)
I have following routes if I run rake routes:
admin_root /admin(.:format) admin/dashboard#index
admin_dashboard GET /admin/dashboard
Then I restart my rails server and go to localhost:3000/admin. I have an error that says cannot get /admin. Can anyone please let me know if I am missing anything?
Active Record Association: why does @owner.@target.count yield a result of 1 when @owner.@target returns an empty array?
I have models in my Rails app:
Sales_Opportunity which has_many Swots.
I'm setting them up using FactoryGirl and running a test to show that when I delete my Sales_Opportunity I also cause the associated Swots to be deleted. For some reason when debugging with Byebug I'm getting strange results - the Sales_Opportunity and Swot records are being correctly created, but when I run sales_opportunity.swots it returns [ ] whereas sales_opportunity.swots.count returns 1. What's more odd is the exact same code works fine with anther object association (timeline_events are exactly like swots yet work perfectly with the same code).
Can anyone tell me what am I doing wrong please?
Sales_Opportunity.rb:
class SalesOpportunity < ActiveRecord::Base
default_scope { order('close_date ASC') }
belongs_to :user
belongs_to :company
has_many :key_contacts
has_many :timeline_events, dependent: :destroy
has_many :swots, dependent: :destroy
end
Swot.rb:
class Swot < ActiveRecord::Base
belongs_to :sales_opportunity
validates :swot_details, presence: true
validates :sales_opportunity_id, presence: true
enum swot_type: [:strength, :weakness, :opportunity, :threat]
enum swot_importance: { minimal: 1, marginal: 2, noteworthy: 3, significant: 4, critical: 5 }
validates :swot_importance, presence: true
end
Swot FactoryGirl spec:
FactoryGirl.define do
factory :swot do
swot_importance "minimal"
swot_details "Some boring details"
swot_type "threat"
trait :attached do
association :sales_opportunity, :with_user_id
end
end
end
Sales_Opportunity FactoryGirl spec:
FactoryGirl.define do
sequence(:opportunity_name) { |n| "Sales Oppotunity - #{n}" }
factory :sales_opportunity do
user
opportunity_name {generate(:opportunity_name)}
close_date "2014/12/12"
sale_value 10000
company_id 7
trait :with_user_id do
user_id 6
end
end
end
Failing Rspec tests:
describe "when swot's parent sales opportunity is destroyed" do
let(:swot) { FactoryGirl.create(:swot, :attached) }
let(:sales_opportunity) { swot.sales_opportunity }
it "should destroy associated swots" do
dswots = sales_opportunity.swots.to_a
byebug
sales_opportunity.destroy
expect(dswots).not_to be_empty
dswots.each do |dswot|
expect(Swot.where(id: dswot.id)).to be_empty
end
end
end
Output from the console (byebug) when logging swot:
#<Swot id: 13, swot_type: 3, swot_importance: 1, sales_opportunity_id: 564, swot_details: "Some boring details", created_at: "2015-07-27 10:57:23", updated_at: "2015-07-27 10:57:23">
Output from the console when logging sales_opportunity:
#<SalesOpportunity id: 564, close_date: "2014-12-12 00:00:00", user_id: 6, created_at: "2015-07-27 10:57:23", updated_at: "2015-07-27 10:57:23", pipeline_status: 0, opportunity_name: "Sales Oppotunity - 4", company_id: 7, sale_value: #<BigDecimal:7fe9ffd25078,'0.1E5',9(27)>, swot_score: 0>
Output for sales_opportunity.swots.count:
(byebug) sales_opportunity.swots.count
1
Output for sales_opportunity.swots:
(byebug) sales_opportunity.swots
#<ActiveRecord::Associations::CollectionProxy []>
I think I've included all the known info. The Rspec tests, FactoryGirl factories and setup between sales_opportunities and Swots/Timeline_Events is exactly the same - yet the Rspec tests pass for Timeline_Events and the collection_proxy works for those (so as far as I can tell, the code is identical):
Timeline_Event Factory:
FactoryGirl.define do
factory :timeline_event do
activity "Some activity"
due_date "2014/11/11"
trait :attached do
association :sales_opportunity, :with_user_id
end
end
end
Working Rspec tests:
describe "when sales opportunity is destroyed for timeline event" do
let(:timeline_event) { FactoryGirl.create(:timeline_event, :attached) }
let(:sales_opportunity) { timeline_event.sales_opportunity }
it "should destroy associated timeline events" do
timeline_events = sales_opportunity.timeline_events.to_a
sales_opportunity.destroy
expect(timeline_events).not_to be_empty
timeline_events.each do |event|
expect(TimelineEvent.where(id: event.id)).to be_empty
end
end
end
Timeline_Event.rb:
class TimelineEvent < ActiveRecord::Base
belongs_to :sales_opportunity
validates :activity, presence: true
validates :due_date, presence: true
validates :sales_opportunity_id, presence: true
end
When running byebug in the same place here I get an array including the Timeline_Event.
Can anyone help me understand what's going wrong in my code?
Thanks.

Stop file write if file size exceeds 500KB ruby on rails
How can I stop file writing ( upload form remote url ) when file size exceeds 500KB ?
I am using following code to upload a remote file
require 'open-uri'
open('temp/demo.doc', 'wb') do |file|
file << open('http://ift.tt/1LJxj3W').read
end
this code is working properly and I am able to get files in temp folder. Now I want if filesize exceeds 500KB then it should stop writing file. In other words I want only 500KB of file if it is more than 500KB

how can I show these submitted values on remotefiles, I think it can be done with render but not sure how can I use it to pass form values and show them on view.
Is there a way to check form data in ruby on rails just like php print_r function ?
How to dynamically load data in Rails 4
So i have this page that has the functionality of creating a new course and listing all courses on the same page.
What i want,is when i click on the id of the courses to dynamically load all lessons associated with that id ion a div below that.
this is the index.html.erb of courses
<% provide(:title, 'All courses') %>
<h1>All Courses </h1>
<p><%= link_to "Back", admin_path, class: "btn-submit" %></p>
<div class="text-center">
<%= form_for [:admin, @course] do |f|%>
<%= render 'shared/error_messages', object: f.object %>
<p>
Create a new course
</p>
<%= f.label :title%>
<%= f.text_field :title%>
<%= f.label :description%>
<%= f.text_area(:description, size: "24x2") %>
<%= f.label :duration%>
<%= f.number_field(:duration, step: 0.5) %>
<%= f.label :category%>
<%= f.text_field(:category) %>
<%= f.label :tag%>
<%= f.text_field(:tag) %>
<%= f.submit "Create Course", class: "btn-submit" %>
<% end %>
</div>
<table class="display responsive no-wrap text-center" id="datatableadmin">
<thead>
<tr>
<th>id</th>
<th>Title</th>
<th>Description</th>
<th>Duration</th>
<th>Category</th>
<th>Tag</th>
<th>Deletion</th>
</tr>
</thead>
<tbody>
<% @courses.each do |c| %>
<tr>
<td><%= c.id %></td>
<td><%= best_in_place c, :title, url: "courses/#{c.id}", cancel_button: 'X' %></td>
<td><%= best_in_place c, :description, url: "courses/#{c.id}" %></td>
<td><%= best_in_place c, :duration, url: "courses/#{c.id}" %></td>
<td><%= best_in_place c, :category, url: "courses/#{c.id}" %></td>
<td><%= best_in_place c, :tag, url: "courses/#{c.id}" %></td>
<td><%= link_to "Remove", admin_course_path(c), method: :delete, data: { confirm: "Are you sure?" }%></td>
</tr>
<% end %>
</tbody>
</table>
<div class="text-center">
<small style="color:red;">Edit by clicking the fields and pressing enter. Cancel by clicking the X button</small>
</div>
so basically if you look down where it says c.id, i want the functionality to call all lessons associated with that id when clicking on that id.
Rails create profile after sign up in devise
i have installed devise in my app and now i want to create profile just after the individual(user) signed up and redirect them to the profile page
here is my individual model
class Individual < ActiveRecord::Base
has_one :profile
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
my profile model is
class Profile < ActiveRecord::Base
belongs_to :individual
before_create :build_profile
end
Migration file for profile is
class CreateProfiles < ActiveRecord::Migration
def change
create_table :profiles do |t|
t.belongs_to :individual, index: true
t.string :first_name
t.string :last_name
t.string :age
t.string :birth_date
t.string :gender
t.string :bio
t.string :linkedin_profile
t.string :facebook_profile
t.string :twitter_profile
t.integer :mobile_no
t.timestamps null: false
end
end
end
and my profiles controller is given as
class ProfilesController < ApplicationController
before_action :authenticate_individual!
before_action :find_profile, only: [:show, :edit, :update, :destroy]
respond_to :html
def index
@profiles = Profile.all
end
def new
@profile = current_individual.build_profile
end
def create
@profile = current_individual.build_profile(profile_params)
if @profile.save
flash[:success] = "Profile saved"
redirect_to current_individual_path
else
flash[:error] = "Error"
render :new
end
end
def show
@profile = Profile.find(params[:id])
end
def edit
end
def update
@profile.update(profile_params)
respond_with(@profile)
end
private
def find_profile
@profile = Profile.find(params[:id])
end
def profile_params
params.require(:profile).permit(:first_name, :last_name, :birth_date,
:gender, :bio, :personal_website, :linkedin_profile, :facebook_profile,
:mobile_no, :telephone_no)
end
end
and i have the routes as
devise_for :individuals
please tell me how can the user will be signed up and after signing in they would be redirected to profile's edit view where the individual can edit the profile Thank you !!

How to organize form_for helper to show data from different models?
I have three models PriceGroup, PriceGroupLine and Item. PriceGroup has fields - :id and :name. Item has fields - :id and :name. PriceGroupLine has fields - :id, :price_group_id, :item_id, :price
Associations:
PriceGroup has_many PriceGroupLines
Item has_one PriceGroupLine
PriceGroupLine belongs_to Item
PriceGroupLine belongs_to PriceGroup
I need to insert in PriceGroupLine model lines from PriceGroup show view. How I should organize form_for helper if I need to insert in PriceGroupLine:
item_id - items list organized with collection_select helper
price_group_id
price of item
And one more question about the associations. At the beginning i had associations like:
PriceGroup has_many PriceGroupLines
PriceGroupLine has_many Items
Item belongs_to PriceGroupLine
PriceGroupLine belongs_to PriceGroup
But this associations didn't work correctly when i tried to get :name field from Item model like this:
<% @price_group.price_group_lines.each do |price_group_line| %>
<%= price_group_line.item.try(:name) %>>
<%= price_group_line.price %>
<% end %>
I changed associations and all worked. Now PriceGroupLine belongs_to :item and Item has_one :price_group_line. But it is logical to assume that ITEM is belongs to PriceGroupLine (PRICEGROUPLINE contains ITEM). Am I wrong?
rails_admin dropdown select in edit
I'm using Rails Admin to manage my website.
Question 1: In Edit, I've got some has many relations fields. When I'm typing something in the dropdown select, for example "eau" (water in french), I've got a big list of ingredients that contain the letters "eau", or an other exemple, for "farine" (flour in french), I've got many type of "farine" but only the word "farine" is all the time at the end. I think it's because "farine" or "eau" are created before the other...
Is there a way to change the order and displaying "farine" or "eau" in first?
Question 2: On the same field, is that possible to search with case insensitive, actually, I would like to search a word without taking accents into account.
Hope someone can help me for this :)
Ruby on Rails: Why doesn't my delete link work?
I am following the Rails guide: http://ift.tt/IsdtVd
and I have the following line in my index.html.erb:
<%= link_to 'Destroy', team_path(team), method: :delete, data: { confirm: 'Are you sure?' } %>
But it doesn't work; it just goes to the show page.
For your information, this is my routes.rb:
Rails.application.routes.draw do
get 'bets/index'
root 'bets#index'
resources :teams
end
My controller:
def destroy
@team = Team.find(params[:id])
@team.destroy
redirect_to teams_path
end
My application.js:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree
//= require jquery
//= require jquery_ujs .
My application.html.erb:
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'defaults', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
Please note that I have tried changing <%= javascript_include_tag 'defaults', 'data-turbolinks-track' => true %> to <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>, but this gives me the following error:
Showing C:/Sites/BettingSite/app/views/layouts/application.html.erb where line #6 raised:

Rails: Multi-Step New User Signup Form (First argument in form cannot contain nil or be empty)
I'm a beginner and have a serious problem with making two steps signing up.
I keep getting that error:
First argument in form cannot contain nil or be empty
<%= form_for(@Profile) do |f| %>
Users can sign up with their user information which are on the user table(DB). And all is fine with them. But I really want them to have profiles. So they can put their bio for example.
I tried to create MVC structure for the profiles based on users' MVC but it doesn't work.
I have been trying to find the answer for days. Tried hundreds of variations but nothing worked out. Please help!
views/users/new.html.erb (This is working)( I just wanted to create profile for the users and give them the ability to fill out their information as the second steps of the signing up)

Ruby on rails Databases with large volumes of data effect speed?
My question is pretty much in the title but I'm wondering if a large quantity of data with largely effect the speed of a database in ruby on rails in my current case I want to store every users games in one database with a id that references to the user however I feel that if I do this eventually that database will get too big and slow the whole website down so will it not matter or would there be a better way of doing something like this?
Thanks in advance
