I am using this source code to send emails in heroku server but it doesn't:
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: "smtp.gmail.com",
port: 25,
authentication: "plain",
user_name: "support@gmail.com",
password: ENV['PASSWORD'],
enable_starttls_auto: false
}
Is there any mistake in my source code. I want to use a free way to send email in my project Thank you
I have an array of hashes that I want to dynamically change the content on the page with. How do I show all the names of the hashes and when clicked, show the array of contacts in that particular hash?
At the moment I only have:
<% @lists.map do |list| %>
<% list.contacts.each do |contact| %>
This shows the contacts for every list, but how do I make only the selected lists' contacts show? I was thinking I could make the display to none for each container div and then when clicked, set that specific div to show - is there a more efficient way to do this?

In my application the user can upload multiple images with Carrier Wave. This images are display in a Fotorama library. So, I want to add some feature that the user can sort the list of the images how he likes.
How I am using postgreSQL with a json column like the tutorial on the docs of the gem. The path of the images are storage like this:
I can not imagine how to do it.
The code that I am using is below:
In the form:
<%= f.file_field :imagens, multiple: true, class: "float-left" %>
In the model
class Product < ApplicationRecord
mount_uploaders :imagens, ImagemUploader
end
The uploader is default by the gem.
It is possible to sort this?
I have four models: Interview, Interviewee, Interviewer and InterviewDate.
The relations in terms of rails associations are as follows:
So, as you can see there are three incoming "Many" relations on the Interview model. How should the routing be done in rails given that I need to perform following tasks in the view ?
List all Interviews grouped by InterviewDate
Form for creation of an Interview (which would also include saving fields from other 3 tables into the database).
I have an application whose server-side is on Rails and the client-side is on React.
I have a situation where I allow a user to create bullet points for a TV show which they create.
These bullet points are sent as params to the Rails side but the issue is if there was a point when there is only one bullet point and then we try to delete it then it doesn't include the bullet_point state in the request.
I added this code to check if bullet point parameter exists, since the only situation it won't exist is when there are no bullet points.
if !prms.has_key?(:bullet_points)
which gives the correct boolean response.
Is there a way to reset bullet points to default in this situation?
bullet_points is an attribute of type text which has been serialized as an Array in the TVShow model
I got a project which is deployed before in evolix server with the domain name www.appname.com ( OVH domain ).
I migrate the project to heroku. After deployment when i click on the link appname.herokuapp.com it's redirected me to www.appname.com which is down as our project is no longer in evolix.
can someone explain me this issue ? and what should I do to fix it ?
I spent so much time looking for a solution but i didn't find something useful is this situation.
Hi everyone I have a question , I looking for on google but I don't find an answer. I'm actually want to display Post model and User model by search in same page and for this I want to use Will_paginate to display all of them . I try this solution =>
**require 'will_paginate/array'
@posts =Post.search(params[:q]).order("created_at DESC")
@users=User.search(params[:q]).order("created_at DESC")
@all_records = (@posts + @users).paginate(:page =>params[:page], :per_page => 10)**
And In my view I want to display all query found ,so I try something like this =>
**<%unless @posts.nil?%>
<% @posts.each do |post| %>
....
**
**<% unless @users.nil?%>
<% @users.each do |user| %>
...**
<%= will_paginate @all_records %>
But it doesn't work nothing happend, so I want to know how to get @posts and @users records in @all_records to do something like this => **
<% @all_records[@posts].each do.. %>
<% @all_records[@usets].each do ..%>
** I saw some solutions that suggest to use two differentes paginate in my view like =>
**<%= will_paginate @posts %>
<%= will_paginate @users %>**
**But It's not want I want , I would'like only one paginate for all, Please Help me cause I'm going crazy, Thank you **
So I have added a new subdomain functionality to my app that's running on heroku
gem 'devise'
gem 'devise-basecamper'
Each User has a subdomain specific for him such as: User.domain.com
Since I have old users I created a temporary functionality to let the old users add a subdomain to their user Account.
But the problem is doing that the Postgresql database is not capable of finding the user to update him:
Here's the error log here
and my application controller
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
helper_method :subdomain, :current_account
before_filter #:validate_subdomain #, :authenticate_user!
before_action :configure_permitted_parameters, if: :devise_controller?
before_filter :set_search
def set_search
@q = User.ransack(params[:q])
@users = @q.result(distinct: true).page(params[:page]).per(10)
end
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up).push(:name, :subdomain)
devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:name, :email, :password, :current_password, :avatar, :memo, :password_confirmation, :subdomain) } #<< :name
end
private # ----------------------------------------------------
def invalidUser
# The where clause is assuming you are using Mongoid, change appropriately
# for ActiveRecord or a different supported ORM.
#@current_user ||= Association.where(subdomain: subdomain).first
User.where("subdomain = ?", subdomain).first
end
def invalidsubdomain
case subdomain
when 'www', '', nil
false
else
true
end
end
def subdomain
request.subdomain
end
# This will redirect the user to your 404 page if the account can not be found
# based on the subdomain. You can change this to whatever best fits your
# application.
def validate_subdomain
if (invalidUser.nil? && invalidsubdomain)
redirect_to '/404.html'
end
end
end
And my routes.rb
Rails.application.routes.draw do
get '/confessions/:id', to: 'users#index', via: 'get'
resources :confessions
devise_for :users, :controllers => { :omniauth_callbacks =>
"users/omniauth_callbacks" ,:registrations => "users/registrations" }
resources :users, :only => [:index, :show]
constraints(Subdomain) do
match '/' => 'users#show' , via: 'get'
end
root to: 'pages#index'
match '/users', to: 'users#index', via: 'get'
match '/users/:id', to: 'users#show', via: 'get'
get '/myconfessions', to: 'pages#myconfessions', as: :myconfessions
get '/search', to: 'pages#search', as: :search
end
And finally my lib/subdomain.rb
class Subdomain
def self.matches?(request)
case request.subdomain
when 'www', '', nil
false
else
true
end
end
end
Thank you prior! any help would be wonderful. I've been stuck on this for a while

I was doing some modification on the website (pure HTML+CSS), deployed it on the server and after refreshing the browser the content was the same.
So I logged in on the server, killed unicorn, started it manually and the new content finally appeared.
How do I do this automatically?
Currently, I have this deploy.rb setup:
# config valid only for current version of Capistrano
lock "3.8.1"
set :application, "project"
set :repo_url, "git@bitbucket.org:username/project.git"
set :branch, "master"
set :tmp_dir, '/home/deployer/tmp'
set :deploy_to, "/home/deployer/apps/project"
set :keep_releases, 5
set(:executable_config_files, %w(
unicorn_init.sh
))
# files which need to be symlinked to other parts of the
# filesystem. For example nginx virtualhosts, log rotation
# init scripts etc.
set(:symlinks, [
{
source: "nginx.conf",
link: "/etc/nginx/sites-enabled/default"
},
{
source: "unicorn_init.sh",
link: "/etc/init.d/unicorn_#{fetch(:application)}"
},
{
source: "log_rotation",
link: "/etc/logrotate.d/#{fetch(:application)}"
},
{
source: "monit",
link: "/etc/monit/conf.d/#{fetch(:application)}.conf"
}
])
namespace :deploy do
desc 'Restart application'
task :restart do
task :restart do
invoke 'unicorn:reload'
end
end
after :publishing, :restart
desc "Make sure local git is in sync with remote."
task :check_revision do
on roles(:web) do
unless `git rev-parse HEAD` == `git rev-parse origin/master`
puts "WARNING: HEAD is not the same as origin/master"
puts "Run `git push` to sync changes."
exit
end
end
end
before "deploy", "deploy:check_revision"
end
What do I need to add yet in order to don't need to manually restart server?
Thank you
Hi I am getting an error with strftime.
My views look like
<%=room.date%> works and yields "2017-07-27".
However I want to convert this to July 27, 2017.
<%= Date.parse(room.date).strftime("%B %e, %Y ") %> Does not work and causes the following error: ActionView::Template::Error (no implicit conversion of Date into String):
My schema has
t.date "date"
I don't know what I am doing wrong. Thanks!

List of relationship between models:
class ErrorScope < ActiveRecord::Base
belongs_to :server
has_many :scope_to_fixflow_map
attr_accessible :id, :server_id, :error_codes, :scoping_method, :priority, :error_codes_is_wildcard_match
serialize :error_codes
.....
end
class ScopeToFixflowMap < ActiveRecord::Base
belongs_to :error_scope
attr_accessible :id, :server_id, :error_scope_id, :path, :fixflow_class_name
......
end
class Server < ActiveRecord::Base
has_many :error_scopes
......
end
Now i have a sql query which gives me desired output:
SELECT fixflow_class_name
FROM error_scopes s
join scope_to_fixflow_maps m on s.id=m.error_scope_id
join servers serv on serv.id=s.server_id
where error_codes regexp 'error_scope_test'
and path = 'x'
and assettag = 'y'
What I tried so far. It works
ErrorScope.where("error_codes like ?", "%error_scope_test\n%").select {|tag| tag.server.assettag == "y"}[0].scope_to_fixflow_map.select {|y| y.path == "x"}[0].fixflow_class_name
using joins
ErrorScope.joins(:server, :scope_to_fixflow_map).where("error_codes LIKE ?", "%error_scope_test%").select {|tag| tag.server.assettag == "y"}[0].scope_to_fixflow_map.select {|y| y.path == "x"}[0].fixflow_class_name
I am sure there must be better way to do this query??

I have a model Booking which contains space_id attributes associated with Space Model by belongs_to :space.
Now I have multiple spaces and want to count each booking with respect to every id.
I want to get the best way to fatch records from DB without fire query again and again. Currently, I'm doing like this:
spaces = Space.all
result = []
spaces.each do |s|
result << s.as_json.merge(:bookings_counts=>s.bookings.count)
end
but this is firing query again and again form db. is there any best way to do this?
I have a file as data/raw/sample�X�}.pdf. The file has special characters .
Now when I try to run the below code to list the file:
Dir["data/raw/*"]
It gives below output:

i.e the special characters like � are getting converted to some octal representation like \357 . I want a ruby code that lists the exact file with special characters.

I have implemented the devise gem on my app and I want to redirect to a specific path after sign_up. I have this method in the registration_controller.rb but its does not work, it redirects to the root path instead of the specified path. I also have devise :confirmable set up but I'm delaying the sent confirmation email until later.
def after_sign_up_path_for(resource)
new_transaction_path(session[:registration_params])
end
And returns the following flash notice: translation missing: en.devise.registrations.store.signed_up_but
How can I make this work?

i have product model, user model and Cart model. in cart model there is a two references 1. user_id , 2.product_id.
I am trying to keep the namespace of a class when including a module. Lets say I have these Models:
class Shop < ApplicationRecord
self.abstract_class = true
end
class A::Shop < ::Shop
end
class B::Shop < ::Shop
end
And this controller:
module A
class ShopController < AuthenticatedController
include Basic::Features
def test
p Shop.new #YES! its a A::Shop
end
end
end
And this Module:
module Basic
module Features
def test
p Shop.new #Shop (abstract)
end
end
end
In the above example, the namespace is overwritten when including the module. As I want to use the Basic::Features module at multiple places in my codebase, I would like to automatically switch between A::Shop and B::Shop when including it in the controller.
Anybody any idea if this is possible, and how.

Hello guys im coding an instagram like app on rails, after i installed the paperclip gem (5.1) i created a model that i must migrate in the db. as i mentioned in the title the rake db:migrate doesnt work. i tried restarting the rails server and my laptop as suggested by some solutions, also tried adding the [5.1] next to the ActiveRecord::Migration like this as others suggested.
class CreatePics < ActiveRecord::Migration[5.1]
after changing some versions it still doesnt work. if its helpful the code project lies here http://ift.tt/2vmEN8a
the error i get is
rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
Directly inheriting from ActiveRecord::Migration is not supported. Please specify the Rails release the migration was written for:

I have a user model with attributes name and city, i am fetching 25 records at a time from server since there are lot of user records
so my routes has this
model(){
return this.get('store').query('user', {page:1}); }
which fetches me the first 25 records
Now in my template i have a button which on click hits the action to fetch the next 25 records ie
action:{
findMoreUsers(){
this.get('store').query('user', {page:2});
} }
Now in the browser, in the ember data the new records are loaded ie it shows 50 records
but when i try to do something like this.get('model'), it gives me the only the old records but not the newly loaded records
So how to to refersh the model so that it shows me all the old as well as new records(50 records)?
Thanks

I've a ruby on rails app which is on 0.0.0.0:3000 and discourse docker container on port 0.0.0.0:80 .

I am going through the 'Installing and Running ruby on Rails 5: Windows' tutorial on lynda. I got the MySQL database up and running and rail installed correctly. After configuring my SQL database with my project, to test it I entered the command 'rails db:schema:dump'. I got the following error:
Failed to load libmysql.dll from C:\Ruby24-x64\lib\ruby\gems\2.4.0\gems\mysql2-0.4.8-x64-mingw32\vendor\libmysql.dll
I checked file explorer and saw that the file does indeed exist. So why is it not loading properly?
I end up with this error - /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in 'require'
I am using a vagrant environment and this is the flow of executing the commands
vagrant up
vagrant ssh
cd /vagrant/
bundle
rake db:create
rake db:migrate
rspec spec //for the tests
and rails s for running it.
Devise before it saves the record, it checks if attributes changed and if so it performs special actions:
def send_devise_notification(notification, *args)
# If the record is new or changed then delay the
# delivery until the after_commit callback otherwise
# send now because after_commit will not be called.
if new_record? || changed?
pending_notifications << [notification, args]
else
# Devise: send emails with background job
devise_mailer.send(notification, self, *args).deliver_later
end
end
The following line gives me an depreaction now:
if new_record? || changed?
DEPRECATION WARNING: The behavior of 'changed?' inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method after 'save' returned (e.g. the opposite of what it returns now). To maintain the current behavior, use 'saved_changes?' instead.
When I use saved_changes? instead of changed? the code won't work correctly anymore, because in this step the record is not yet saved
e.g.
user.email = "hello@example.com"
user.changed? => true
user.saved_changes? => false
Which method should I use instead? How can I prevent the depreaction warning? Thanks
I could request a page that does not exists and I would suppose a 404 would be send, but with the configuration below I receive mails for other errors but not for 404.

How do I deploy Ruby on Rails remotely connected a Cassandra database in Docker? Can any one help me on this?
When I try to use a rake task that isn't rake db:create that uses a DB connection (ie rake db:migrate) Connection refused - sendto(2) for "127.0.0.1" port 9999
Inexplicably, it tries to connect on non-default port (9999) that, as far as I can tell, not in the config (ie config/database.yaml) . When I change MySQL to use this port, I get a slightly different error: Mysql2::Error: Can't connect to MySQL server on '127.0.0.1' (61)
MySQL server is a vanilla homebrew install, if that matters (whole thing is running on MacOS 10.12.3)
I am using rails attr_encrypted gem for encrypting data before storing in database. It works fine on my application as it encrypts with the provided key and decrypts it using the same key via my application. But when I create a instance with my rails console, it does not encrypt with the key that is provided in the application ( uses some random key each time maybe) and hence I am not able to decrypt it when I see that instance in my application.
Below picture shows that if I create the user with the same name twice in console, each time the encrypted data is different. I am following the tutorial on this page
When I try to access the page on my application, the user made by console are showing this error
I'm working with a friend on a projet with RoR + Devise for authentication.
My friend is doing an application with React Native.
I'm actually trying to build with my existing RoR project an API.
namespace :api do
namespace :v1 do
# Users
get '/users' => 'users#index'
get '/users/:id' => 'users#show'
end
end
# BaseController
class Api::V1::BaseController < ApplicationController
protect_from_forgery with: :null_session
before_action :destroy_session
rescue_from ActiveRecord::RecordNotFound, with: :not_found!
def destroy_session
request.session_options[:skip] = true
end
def not_found!
return api_error(status: 404, errors: 'Not found')
end
def api_error(status: 500, errors: [])
unless Rails.env.production?
puts errors.full_messages if errors.respond_to? :full_messages
end
head status: status and return if errors.empty?
render json: jsonapi_format(errors).to_json, status: status
end
end
# UsersController
class Api::V1::UsersController < Api::V1::BaseController
before_action :find_user, only: [:show]
def index
@users = User.all
render json: @users
end
def show
render json: @user
end
private
def find_user
@user = User.find(params[:id])
end
def user_params
params.require(:user).permit(:username, :email, :password)
end
end
I configured my Serializers too.
My question is :
How can i handle with Devise and API configuration, registrations / sessions controllers ?
i have a model which has_many relation to a version model. Any action on the parent model need to be tracked. At the form for delete i have added a nested form to enter a ticket number which will be added to the versions. How could i check in the model validations if the ticket is given? I will write the version before the destroy on the model is called.
# model.rb
class Model < ActiveRecord::Base
has_many :versions,
:as => :version_object
end
# models_controller.rb
def destroy
@model = Model.find(params[:id])
self.write_versions('Destroy')
@Model.destroy
respond_to do |format|
...
end
end
# delete.html.erb
<%= form_for [@model.parent_object, @model], :html => { :class => 'form-horizontal' }, :method => :delete
do |f| %>
<div class="form-actions">
<%= f.fields_for :versions, @model.versions.build do |v| %>
<%= v.text_field :ticket, {:class => 'text_field', :placeholder => 'Ticket Nummer'}%>
<% end %>
<%= f.submit 'Delete Model', :class => 'btn btn-danger' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
:back, :class => 'btn' %>
</div>
<% end %>
I already tried to implement a before_destroy method to check if a version with the 'Destroy' action is written but this won't work because the key fields to identify the certain action could be exist more than one time. The versions are incremental and can be rolled back step by step to get an older version and my model could have more than one relation identifier at the lifetime of his parent.
An solution would be to check the existence of the ticket at the controller through the params, but validations should be at the model.
I don't want to use a versioning gem.
Anybody a hint how to implement such a validation?
Sometimes I need some consultations on ruby/rails/smth_else best practices or just smth like 'am I doing right?' I know it's no good to place them here, so I wonder if there are some sources on the Internet where I can ask such a question?
I have this date that which is in timezone offset format that I need to convert to UTC format. For example:
date1 = 2017-07-13T17:13:12-04:00
date2_utc = 2017-07-13 21:13:12 UTC
I need to compare if those two date are same date. Or If I can convert date1 to UTC then i can compare those two.

I work on a rather complex Ruby project that has multiple interdependencies. With recent bundle update, I got logging-rails (0.6.0) pulled in, and that's where mystery started. Attempts to load the project failed, and I tracked them down to this line in that newly updated gem failing with an error:
NameError: method `logger' not defined in ActionView::Base
OK, I thought, so logger methis not defined somehow, let's figure out why. I opened the logging-rails code in editor and added some debug output before problematic line. But after I ran the project again, I got really puzzled with the results it yielded. Namely:
puts "#{LOGGER_METHOD.inspect} is included: #{ other.instance_methods.include?(LOGGER_METHOD)}"
=>
:logger is included: true
puts other.method(:logger).source_location.inspect
=>
["/CENSORED/.bundle/gems/ruby/2.3.0/gems/actionpack-3.2.22.5/lib/action_view/base.rb", 149]
puts other.method(:logger).inspect
=>
#<Method: ActionView::Base.logger>
And ultimately:
result = nil
begin
ActionView::Base.logger
result = "success"
rescue
result = "failure"
end
puts result
=>
success
I'm at a total loss now. The method is defined; Ruby knows exactly where; it executes just fine and returns a result; but when it comes to undefining the method, it's suddenly not defined? WTF?..

So I was trying to implement a favouriting system for an app of mine and followed this guide:
The particular setup you describe mixes several types of associations.
First we have a User model and second a Recipe model. Each recipe belonging to one user, hence we have a User :has_many recipes, Recipe belongs_to :user association. This relationship is stored in the recipe's user_id field.
$ rails g model Recipe user_id:integer ...
$ rails g model User ...
class Recipe < ActiveRecord::Base
belongs_to :user
end
class User < ActiveRecord::Base
has_many :recipes
end
Next we need to decide on how to implement the story that a user should be able to mark favorite recipes.
This can be done by using a join model - let's call it FavoriteRecipe - with the columns :user_id and :recipe_id. The association we're building here is a has_many :through association.
A User
- has_many :favorite_recipes
- has_many :favorites, through: :favorite_recipes, source: :recipe
A Recipe
- has_many :favorite_recipes
- has_many :favorited_by, through: :favorite_recipes, source: :user
# returns the users that favorite a recipe
Adding this favorites has_many :through association to the models, we get our final results.
$ rails g model FavoriteRecipe recipe_id:integer user_id:integer
# Join model connecting user and favorites
class FavoriteRecipe < ActiveRecord::Base
belongs_to :recipe
belongs_to :user
end
---
class User < ActiveRecord::Base
has_many :recipes
# Favorite recipes of user
has_many :favorite_recipes # just the 'relationships'
has_many :favorites, through: :favorite_recipes, source: :recipe # the actual recipes a user favorites
end
class Recipe < ActiveRecord::Base
belongs_to :user
# Favorited by users
has_many :favorite_recipes # just the 'relationships'
has_many :favorited_by, through: :favorite_recipes, source: :user # the actual users favoriting a recipe
end
##
# Association "A"
# Find recipes the current_user created
current_user.recipes
# Create recipe for current_user
current_user.recipes.create!(...)
# Load user that created a recipe
@recipe = Recipe.find(1)
@recipe.user
##
# Association "B"
# Find favorites for current_user
current_user.favorites
# Find which users favorite @recipe
@recipe = Recipe.find(1)
@recipe.favorited_by # Retrieves users that have favorited this recipe
# Add an existing recipe to current_user's favorites
@recipe = Recipe.find(1)
current_user.favorites << @recipe
# Remove a recipe from current_user's favorites
@recipe = Recipe.find(1)
current_user.favorites.delete(@recipe) # (Validate)
There may be several approaches on how to implement Controller actions and routing. I quite like the one by Ryan Bates shown in Railscast #364 on the ActiveRecord Reputation System. The part of a solution described below is structured along the lines of the voting up and down mechanism there.
In our Routes file we add a member route on recipes called favorite. It should respond to post requests. This will add a favorite_recipe_path(@recipe) url helper for our view.
# config/routes.rb
resources :recipes do
put :favorite, on: :member
end
In our RecipesController we can now add the corresponding favorite action. In there we need to determine what the user wants to do, favoriting or unfavoriting. For this a request parameter called e.g. type can be introduced, that we'll have to pass into our link helper later too.
class RecipesController < ...
# Add and remove favorite recipes
# for current_user
def favorite
type = params[:type]
if type == "favorite"
current_user.favorites << @recipe
redirect_to :back, notice: 'You favorited #{@recipe.name}'
elsif type == "unfavorite"
current_user.favorites.delete(@recipe)
redirect_to :back, notice: 'Unfavorited #{@recipe.name}'
else
# Type missing, nothing happens
redirect_to :back, notice: 'Nothing happened.'
end
end
end
In your view you can then add the respective links to favoriting and unfavoriting recipes.
<% if current_user %>
<%= link_to "favorite", favorite_recipe_path(@recipe, type: "favorite"), method: :put %>
<%= link_to "unfavorite", favorite_recipe_path(@recipe, type: "unfavorite"), method: :put %>
<% end %>
That's it. If a user clicks on the "favorite" link next to a recipe, this recipe is added to the current_user's favorites.
I hope that helps, and please ask any questions you like.
The Rails guides on associations are pretty comprehensives and will help you a lot when getting started.

some help would be appreciated
I am using delayed job to queue a Model method in another Model like this:
article_loader.rb
date_value_in_string = "2017-06-21 07:17:00"
Article.delay(:queue => 'article_load').article_loading([date_value_in_string])
Even though I have passed a String as an argument to the method, inside the method it gets converted to Time object in the production environment.
article.rb in production environment
def self.article_loading(args)
date_value = args[0]
p date_value.class # Time
end
While in development environment it is a string.
article.rb in development environment
def self.article_loading(args)
date_value = args[0]
p date_value.class # String
end
I don't know why this happens. Any help will be appreciated.
Below code are written in the controller action where we are generating a different action based on the action parameter and secondary we are only generating the xml response on the basis of different action parameters.It's not necessary that every case of action consist result tag as parent.It's vary between action to action.
doc = EncodeDecode.decode(request.raw_post)
action = parse_xml(doc/'action') if (doc/'action').first
# action = 'fetch_thread_colors'
case action
when 'create_customer_profile'
result = Customer::CustomerCrud.create_customer_profile(doc)
render :xml => "<result>#{result}</result>"
when 'create_customer_payment_profile'
result = Customer::CustomerCrud.create_customer_payment_profile(doc)
render :xml => "<result>#{result}</result>"
How we can achieve the best way to implement because My problem is that it's to big in term of line of codes I am having more than 300-350 cases in the switch block.Is there any way something I can achieve it using metaprogramming But we also need to consider the point for memory efficient.
Solutions should be efficient ,clean and optimized to implement.
Any object oriented approach also can help me out.
Polymorphic relationships don't work when the models are namespaced in rails 3.1. Here is an example:
class Accounting::Request::Check < ActiveRecord::Base
has_one :accounting_request, as: :requestable
def self.table_name
'accounting_request_checks'
end
end
class Accounting::Request < ActiveRecord::Base
belongs_to :requestable, polymorphic: true
def self.table_name
'accounting_requests'
end
end
cr = Accounting::Request::Check.create!()
cr.create_accounting_request
Results in:
NameError: uninitialized constant Accounting::Request::Check::AccountingRequest
My question is, how can I work around this for the time being before we migrate to rails 5?
One solution I found was to add class_name: '::ClassName' but this doesn't work for me.
I am using I18n for internationalization. for displaying place holder content in locale language in placeholder of text_field_tag im using following code.
<%= text_field_tag('email', "", class: 'form-control', placeholder: t('shared.enter_email')%>
And config/locales/en.yml content is as follows:
en:
shared:
enter_email: Enter Email
on running application, the content in the placeholder contains only Enter and its ignoring name because there is a space in-between.
i tried different syntax, all are producing same result. Is there a way to get this done?

I need a tree structure like this
parent1(first taxon(first record) with all child if it has)
- child1
- child2
- child3
- child7
- child9
- child4
- child5
parent2(it has no child)
parent3(Not it has child)
- child7
- child9
i short i need each individual taxon with its nested child...
i have tried like
Taxon.all.each do |i|
i.self_and_descendants.each do |j|
taxon_with_childs << j
end
but this gives plain array but i want array with parent child nesting
i have also tried
Taxon.each_with_level(Taxon.root.self_and_descendants) do |taxon, level|
taxon_with_childs << taxon
end
but this is giving only first record's children and that to not deep nesting
Can any one please help me where i am wrong
I have a module where all our Accounting ActiveRecord classes live within. I have an AR class called Requests and a subclass called Check (logically there will be multiple types of requests for accounting)
In my test suite for Accounting::Requests::Check I have the following tests:
subject(:check) { build(:check_with_items) } # Uses FactoryGirl
it "should have the right table name" do
expect(Accounting::Requests::Check.table_name).to eq('accounting_request_checks')
end
it "should be a valid factory instance" do
expect(check).to be_valid
end
Which pass and are correct.
However, when I do the following within an ActiveAdmin.register_page block:
ActiveAdmin.register_page 'Accounting Requests' do
... menu stuff
controller do
def index
@check = Accounting::Requests::Check.new
end
I get the this error:
PG::UndefinedTable: ERROR: relation "accounting_checks" does not exist
My test ensures that this model has the right table name, being "accounting_request_checks", yet AA is looking for "accounting_checks".
Directory structure:
/models
/accounting
request.rb
/requests
check.rb
Here are the class declarations:
class Accounting::Requests < ActiveRecord::Base
class Accounting::Requests::Check < ActiveRecord::Base
Why is active admin looking up the incorrect table name?
I've also tried changing requests from a class to a module with a function using self.table_name_prefix (that's a Rails 3.1 method)
update:
It's not ActiveAdmin - in rails console doing Accounting::Requests::Check.new gives the same error.
My spec is:
expect { result }.to raise_error(ArgumentError)
#=> expected ArgumentError but nothing was raised
When I put debugger in the code, result is:
(pry) output error: #<ArgumentError: (...)
What's wrong with the spec? I use rspec-given
In a implementation of gem: http://ift.tt/2tXriyB
When i go to Post Job new page show this error on the log
undefined method `country' for #
I've tried to put the

in the job model, but did not worked.
Someone have any hint to spare?
Job Model
class Job < ActiveRecord::Base
belongs_to :user
belongs_to :location
accepts_nested_attributes_for :location, allow_destroy: true
default_scope -> { order(created_at: :desc) }
end
Location Model
class Location < ActiveRecord::Base
has_many :users
has_many :jobs
end
Job new view
<%= simple_form_for @job do |f| %>
<%= f.simple_fields_for :location do |l| %>
<%= l.input :country, label: "Country", collection: CountryStateSelect.countries_collection %>
<%= l.input :state, CountryStateSelect.state_options(label: "State / Province", form: f, field_names: { :country => :country, :state => :state } ) %>
<%= l.input :city, CountryStateSelect.city_options(label: "City ", form: f, field_names: { :state => :state, :city => :city } ) %>
<% end %>
<%= f.input :name, label: 'Name', error: 'Name is mandatory' %>
<%= f.input :description, placeholder: 'user@domain.com' %>
<%= f.button :submit %>
<% end %>
I am using delayed job to queue a Model method in another Model like this:
article_loader.rb
date_value_in_string = "2017-06-21 07:17:00"
Article.delay(:queue => 'article_load').article_loading([date_value_in_string])
Even though I have passed a String as an argument to the method, inside the method it gets converted to Time object.
article.rb
def self.article_loading(args)
date_value = args[0]
p date_value.class # Time
end
I don't know why this happens. Any help will be appreciated.
I have a rails app which was perfectly working for me in my default rails development environment, but when I installed Vagrant VM and ran my app on Ubuntu 12.04 I have this error that says
Mysql2::Error (Can't connect to local MySQL server through socket 'MySQL' (2)):
As far as I understood is that my ubuntu VM cannot load Mysql server through socket MYSQL that was working for my default windows, so I tried to remove socket: MySQL line from my rails database.yml
default: &default
adapter: mysql2
encoding: utf8
pool: 5
username: root
password: xxxxx
socket: MySQL
host: localhost
But then I get the error saying my database is not found, I can't seem to fig out how can I look for my database from window and load it in Ubuntu VM ??
here is the log that gives absolutely no info .. :/
Mysql2::Error (Can't connect to local MySQL server through socket 'MySQL' (2)):

Any Ideas on how to make it work ?
I've two models, Doctor and Clinic where a doctor has_many clinics.
Clinic have doctor_id and a boolean active field.
What I want:
I want to get all doctors which does not have any active (active field is true) clinics i.e. either doctor does not have any clinics or does not have any clinics where active field is true.
What I've tried so far:
Try 1:
scope :incomplete_doctors, -> { includes(:clinics)
.where("( doctor_clinics.id IS NULL ) OR
( doctor_clinics.id IS NOT NULL AND
doctor_clinics.active=?)", false )
}
Try 2:
scope :incomplete_doctors, -> { where("id NOT IN (?)", self.includes(:clinics)
.where("( doctor_clinics.doctor_id IS NULL ) OR
( doctor_clinics.doctor_id IS NOT NULL AND
doctor_clinics.active=?)", false )
.select(:id))
}
Try 3:
SELECT "doctors".* FROM "doctors"
LEFT OUTER JOIN "doctor_clinics" ON "doctor_clinics"."doctor_id" = "doctors"."id"
WHERE ( ( doctor_clinics.id IS NULL ) OR
( doctor_clinics.id IS NOT NULL AND
doctor_clinics.active='f'))
GROUP BY doctors.id
HAVING 'true' <> ANY(array_agg(DISTINCT doctor_clinics.active::TEXT));
Success:
I'm able to achieve desired output using following method, but I want to achieve this using a SQL query.
def active_clinics
clinics.active_clinics # active_clinics is a scope in Clinic model while give all active clinics
end
def self.incomplete_doctors
(Doctor.all.map { |d| d unless d.active_clinics.present? }).compact
end
Help please. I get:

ruby 2.3.3, rails 3.2.22.5
Hi. I'm using a serialized :logs, Hash in a User model, when saving the logs hash- afterwards it's being retrieved as string instead of Hash.
How it happen:
So for user when assigning value to logs hash: user.logs[2] = 4, then saving
class User < ActiveRecord::Base
serialize :logs, Hash # in database it's a text type
end
An example in the rails console:
# rails console
test_user_id = 3
user = User.find(test_user_id)
user.logs = {}
user.save
user.logs # => {} # great
User.find(test_user_id).logs # => {} # great
# now trying to add value and save:
# 1. assign value to logs hash
user.logs[Time.now] = {:field_id=>6} # => {:field_id=>6}
# 2. save user object:
user.save
# 3. now logs hash is a string..
user.logs
#=> "---\n2017-07-03 19:33:34.938364000 +03:00:\n :field_id: 6\n"
# why it turned to string ?!?!
User.find(test_user_id).logs # same here:
# => "---\n2017-07-03 19:33:34.938364000 +03:00:\n :field_id: 6\n"
Any ideas?
I'm starting with ruby and rails and I want to create a helper to show this form :
<%= form_for( :user, :url => session_path( :user) ) do |f| %>
<%= f.text_field :email %>
<%= f.password_field :password %>
<%= f.check_box :remember_me %>
<%= f.label :remember_me %>
<%= f.submit 'Sign in' %>
<%= link_to "Forgot your password?", new_password_path( :user) %>
<% end %>
So I just have to call my function show_login-form and display my form :) but I don't know how :(
Thanks
