Deep nested resources rails - ruby-on-rails

Question

I understand deep nested resource should not be adopted, however i do not know how to convert it properly to a 1 level nested resources. If clean tutorial exists show me the tutorial and I will learn it. If not Then please help with my problem. Here my route.rb
resources :article do
resources :picture
resources :comments do
resources :repcomments
end
end
resources :reports
I can do article, picture, comments but not to sure how to approach the third level of reports. The idea comes that an article can have comments and where the comment could be reported to management. Everythings plays in the article#show pages and here the controller
def show
#art = Article.find(params[:id])
#comments = #art.comments.find(:all, :order => 'created_at DESC')
respond_to do |format|
format.html # show.html.erb
format.json { render json: #art }
end
end
Here the view form in article#show
<%= #art.title %>
<%= #art.content %>
Comment
<%= form_for [#art, current_customer.comments.new] do |f| %>
<%= f.text_area :description %><br />
<%= f.submit "Add Comment" %>
<% end %>
# End of form comments
<% #comments.each do |comment| %>
<%= comment.description %>
<div>Report</div>
<%= form_for [#art, comment, repcomments.new] do |f| %>
<%= f.text_area :body %><br />
<%= f.submit "Report it" %>
<% end %>
<% end %>
I am getting a no define method and not to sure how to approach it. Thanks in advance
Here the route file
article_comment_repcomments GET /articles/:article_id/comments/:comment_id/repcomments(.:format) repcomments#index
POST /articles/:article_id/comments/:comment_id/repcomments(.:format) repcomments#create
new_article_comment_repcomment GET /articles/:article_id/comments/:comment_id/repcomments/new(.:format) repcomments#new
edit_article_comment_repcomment GET /articles/:article_id/comments/:comment_id/repcomments/:id/edit(.:format) repcomments#edit
article_comment_repcomment GET /articles/:article_id/comments/:comment_id/repcomments/:id(.:format) repcomments#show
PUT /articles/:article_id/comments/:comment_id/repcomments/:id(.:format) repcomments#update
DELETE /articles/:article_id/comments/:comment_id/repcomments/:id(.:format) repcomments#destroy
Here the models
class Repcomments < ActiveRecord::Base
belongs_to :customer
belongs_to :article
attr_accessible :acknowledged, :body, :completed, :customer_id, :article_id
end
Here my controller repcomments
class RepcommentsController < ApplicationController

#article = Article.find(params[:article_id])
#comments = #articles.comments.find(params[:comment_id])

#repcomment.destroy
respond_to do |format|
format.html { redirect_to repcomments_url }
format.json { head :no_content }
end
end
end
NameError in Article#show
Showing /home/jean/rail/voix/app/views/articles/show.html.erb where line #70 raised:
undefined local variable or method `repcomments' for #<#<Class:0xaf24860>:0xaafe934>
So pretty much is the referencing

Answer 1

Just looking at your code, I can see one problem in your routes: :article and :picture need to be plural.
resources :articles do
resources :pictures
resources :comments do
resources :repcomments
end
end
resources :reports
Also, you don't need to nest :repcomments within :articles. In addition to what you already have in your routes, you can add:
resources :comments do
resources :repcomments #and remove the other "resources :repcomments"
end
Yes, you would have resources :comments defined twice, but that's fine.
If you never do anything with comments outside the article scope, then you can write your routes like that:
resources :comments, only: [] do
resources :repcomments
end
This way Rails wont generate the default rest routes (no /comments, no /comments/:id etc)
