I have tried using Ruby Installer but I keep on getting compatibility issues between my ruby version and my rails version.
I have a table in my rails API called "Visions" and within that table I have 4 columns for images:
I am able to successfully receive image_url of 'image' however I also want to be able to get the url for the remaining 3 image columns.
This is what I have in _vision.json.jbuilder:
json.call(
vision,
:id,
:description,
:hairdate,
:products,
:rating,
:drying,
:hairday,
:styling,
:created_at,
:updated_at
)
json.image_url polymorphic_url(vision.image)
adding json.imagetwo_url polymorphic_url(vision.imagetwo) etc to the end of the code breaks the app and prevents data being sent to my react native front-end.
vision.rb:
class Vision < ApplicationRecord
has_one_attached :image
has_one_attached :imagetwo
has_one_attached :imagethree
has_one_attached :imagefour
belongs_to :user
def featured_image_url
if self.image.attachment
self.image.attachment.service_url
end
end
end
visions_controller.rb:
def index
@visions = current_user&.visions
render :index, status: :ok
end
def new
@vision = Vision.new
end
def create
@vision = current_user&.visions.create(vision_params)
render :create, status: :created
end
def destroy
@vision = current_user&.visions.where(id: params[:id]).first
if @vision.destroy
head(:ok)
else
head(:unprocessable_entity)
end
end
def update
@vision = current_user&.visions.where(id: params[:id]).first
if @vision.update(edit_vision_params)
head(:ok)
else
head(:unprocessable_entity)
end
end
private
def vision_params
params.permit(:description, :image, :imagetwo, :imagethree, :imagefour, :hairdate, :rating, :products, :hairday, :drying, :styling)
end
end
I currently have following codes
<code data-bind="text: xxx, highlightable: true"></code>
And I want to bind something like App::Application::CONFIGURATION[:url] into text of the data-bind
I tried <code data-bind="text: <%=App::Application::CONFIGURATION[:url] %>, highlightable: true"></code> but it didn't work.
Hope that someone can help me solve this problem. I appreciate your help!

I am using some tutorial to create a dynamic form in which i should be able to add json object array of amounts.
i should get this params from form
quote_amounts: [
{"kind"=>"website", "label"=>"Website", "amount"=>10000.0},
{"kind"=>"website_review", "label"=>"Website Review", "amount"=>12000.0}
]
I have created created the controller in this way
def create
@quote.assign_attributes(quote_params)
if @quote.save
@quote.submit_quote
@name = @quote.contact.user.display_name
redirect_to confirm_form_submission_path
else
render :new
end
end
and
def quote_params
params.require(:vendor_quote).permit(:notes, quote_amounts: [])
end
and I have created this form
<%= f.number_field :amount, min: 0, prepend: '$', required: true %>
<%= f.text_field :label, required: true %>
<%= f.text_field :kind, required: true %>
<%= f.text_area :notes %>
<%= f.submit "Submit quote", class: "btn btn-info btn-lg btn-block btn-rounded text-uppercase" %>
by this i am getting this error
undefined method `amount' for :amount
and please tell me that how to add 'add more' button so i can add multiple quote_amounts and save it into one json array object in single form.
This is what I currently have in my Vision model:
has_one_attached :image
belongs_to :user
def featured_image_url
if self.image.attachment
self.image.attachment.service_url
end
end
end
in my Vision controller:
def create
@vision = current_user&.visions.create(vision_params)
render :create, status: :created
end
def vision_params
params.permit(:description, :image)
end
and in _vision.json.jbuilder:
json.call(
vision,
:id,
:description,
:created_at,
:updated_at
)
json.image_url polymorphic_url(vision.image)
I am using Amazon S3 for image storage. How can I change my code to be able to upload multiple image files?
Please also bear in mind that I have existing data in my database where I am getting an image URL for one single Image per Vision. How can I make the changes without affecting my existing database?
Thank you in advance 🙏🏼

I have a list of keywords to be excluded from search here
KEYWORDS = %w[
covid corona subway railway travel plane brazil ]
exclude = Twitter::KEYWORDS.split(",").join(" -")
and this is how my search query looks like
json_response = @client.search("(javascript) -#{exclude}", lang: "en", result_type: "recent", tweet_mode: "extended", count: 100)
How can I pass multi-word keywords here to be excluded, for example keywords like "off the hand" or "game plan"?
Adding them along with the other keywords doesn't work as expected.
I have both controller and view for a simple game I've created.
This is my function :
def score
@letters = params[:letters]
@word = params[:word].upcase
if !compsrison?(@word.split(''), @letters.split)
@result = "Sorry, but #{@word} can't be build out of **#{@letters}**"
elsif !check_api?(@word)
@result = "Sorry, but **#{@word}** doesn't seem to be valid English word..."
else
@result = "Congratulations! **#{@word}** is a valid English word!"
end
end
and simply my view for a result :
<div class="result">
<%= @result %>
</div>
I would like my params[:word] and params[:letters] to be a bold text looking sth like that:1
I can't seem to find the build-in method in ruby for a bold text or change it in my erb file.
thanks!

we are trying to upgrade ruby version of our rails application, currently, it's running in ruby 1.8.7 as a initial step trying to upgrade 1.9.2
when we trying to run ./bundle exec rails s we are getting below error
vendor/local/polyglot-0.3.3/lib/polyglot.rb:63:in `require': libruby.so.1.8: cannot open shared object file: No such file or directory - /home/sakthi/Sakthi/trunk_upgrade_v1/vendor/local/libxml-ruby-2.4.0/lib/libxml_ruby.so
but I can see llibxml_ruby.so file that path
when writing User.all
However I don't get this error when using rails c
I have only two models:
user.rb
class User < ApplicationRecord
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :validatable
has_many :items end
item.rb
class Item < ApplicationRecord
belongs_to :user end
my gemfile includes
gem 'devise'
I've checked the models and controller names (singular and plural), and restarting the console I've tried running spring stop and didn't fix the issue
The below code is throwing "undefined method `name' for nil:NilClass". I've been trying to understand this but everything I read says that try should never throw a NoMethodError when the receiving object is nil.

How to use find_by_username with case_sensitive: false?
I explain my issue. I have this script to take the username tagged (after @) and to check if it is a "existing user" or not.
text.gsub! (/@(\S+)/) do |match|
user = User.find_by_username($1)
if
else
end
end
In this way if the text is @Mike and the user signed is Mike, it is ok. BUT if the text is @mike and the user signed is Mike, it doesn't work.
Hot to add a case_sensitive false in find_by_username?
This is sample code which i am trying to handle exception from unicorn.
unicron.rb
worker_processes Integer(ENV['WEB_CONCURRENCY'] || 3)

Sample code
def create_store
ActiveRecord::Base.transaction do
@store = Store.new(params[:store])
if @store.save!
sleep 12.3
InformUserWorker.perform_async(store_id)
end
end
rescue => exception
exception.backtrace.each { |trace| puts trace }

puts 'That took too long, exiting...2'
rescue Rack::Timeout::RequestTimeoutError
puts 'That took too long, exiting...3'
rescue Rack::Timeout::RequestExpiryError
puts 'That took too long, exiting...4'
end
I am getting code=H13 desc="Connection closed without response" with this sleep 12.3 seconds, and the transaction rollback happens, but none of these exceptions are executing. I have added couple of exception here. Anything goes wrong here?.
I have a scope on a booking model, that takes bookings into the current period of 15 days. it works, so, in production, after one day i seen that not works, on the log applies the scope filter from the moment deployment was done.
First, scope looked as this:
scope :current_availables, where(date: Date.today..Date.today+14.days )
And now the scope looks like this
scope :current_availables, where(date: Date.current.beginning_of_day..Date.current+14.days )
What is happening?

If given the following object:
Animal {
......
owned: true
}
Is there a way to check if a given animal was owned within a month? Specifically, is there a way to check when the owned field was changed to false/true via Active record?.
Or would I need to set up a separate object that tracks that field's history?
I was already able to replace the posts using AJAX upon submitting the form. The problem though, is that the URL is not updating to include the params I added.
When I click on Submit, the values are passed to the controller. I can call params[:tags] and it will return the IDs. However, the URL is still localhost:3000/posts/:id and it didn't include the tag_ids.
Here are the affected files:
posts_controller.rb:
def show
@posts = get_posts
respond_to do |format|
format.js
format.html
end
end
posts/show.html.haml:
#posts
= render "posts", { posts: posts }
= form_tag url_for(:only_path => false), method: :get, remote: true, id: "posts-form" do
@tags.each do |tag|
= check_box_tag "tags[]", tag[:id]
= tag[:name]
= submit_tag "Filter"
posts/show.js.erb:
$('#posts').html("<%= j (render 'posts', posts: @posts) %>")

I have a marketplace application where users can create both products and categories. In the product's _form.html.erb
In the product _form.html.erb a user can create a product and assign it one category. The issue is that the category 'form.select' displays all categories that all users have created.
How can I rewrite
<div>
<%= form.select :category_id, Category.all.map {|c| [c.category, c.id]} %>
</div>
to display the categories only the current user has created?
--
<%= form_with(model: product, local: true) do |form| %>
<% if product.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(product.errors.count, "error") %> prohibited this product from being saved:</h2>
<ul>
<% product.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :title %>
<%= form.text_field :title %>
</div>
<div class="field">
<%= form.label :description %>
<%= form.text_area :description %>
</div>
<div class="field">
<%= form.label :price %>
<%= form.text_field :price %>
</div>
<div>
<%= form.select :category_id, Category.all.map {|c| [c.category, c.id]} %>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
but it lists all the categories in the database. How do I write this code so the form lists only the categories the user has produced.

stage table has one_to_many association with task table. task table has attribute stage_id.
In my excel file there is parent child ID column like 1,2,3,4 is stage and 1.1,1.2..4.1..so on is task.
i want to import that file but the problem is how i'll take stage_id of new created row and put them is task table. so that while retrieving data no problem is faced.
if there is alternate easy solution to solve such problem please provide that solution. I have to save that in order, so that i can identify which has child and which is parent also there order.

end
def show
@category = Category.find(params[:id])
end
private
def category_params
params.require(:category).permit(:name)
end
def find_post
@category = Category.find(params[:id])
end
end
This is my index page where i want to show all my categories
<h1>ALL CATEGORIES</h1>
<% @category.each do |c|%>
<ul><%= link_to c.name, categories_path(category) %></ul>
<% end %>

root 'category#index'
post '/category' => 'category#create'

get '/category/:id' => 'category#show', as:'categories'
end Why i am getting this name error? undefined local variable or method category' for enter code here`#<#Class:0x00007feddc03ad50:0x00007fede47f8378> Did you mean? @category
Im looking to have a user create a post where they specify what instruments they play. There should be a checkbox for each instrument so the user can select the ones that apply to the post. I was able to display the instruments and their checkboxes in the post creation but I cannot figure out how to save them to the post. I get error ActiveRecord::AssociationTypeMismatch.
Displaying all instruments and passing integers for each (Id like to pass strings)
<% Instrument.all.each do |instrument| %>
<%= check_box_tag "post[instruments][]", instrument.id %>
<%= instrument.name %> <br>
<% end %>
<div class="actions">
<%= form.submit %>
</div>
Migration to receive array of integers
class AddTagsToPost < ActiveRecord::Migration[5.2]
def change
add_column :posts, :instruments, :integer, array: true, :default => []
end
end

create_table "instruments", force: :cascade do |t|
t.string "name"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end

t.bigint "category_id"
