Two resources using the same resource

Question

Well, I didn't know how to title this. This was my best guess. Here's my problem:

I'm having Issues and Reviews controllers. Both of them should have a Comments controller nested.

Do I have to generate two separate scaffolds like icomment for the Issues and rcomment for the Reviews or is there a way to use the resource simultaneously for both?

These two controllers are already nested, so i guess it would get pretty messy to maintain this. What would be the best approach for this?

Answer 1

You can leave it at the same level as the two commentable objects:

namespace :whatever
  resources :comments
  resources :issues
  resources :reviews
end

And force the requests to /whatever/comments to have values for the params[:commentable_id] (for Create, Update and Edit) and the params[:commentable_type] (for all CRUD) ;)

An example of a nested form for the Issue model:

# issues controller
before_filter :set_issue, only: [:new, :edit, :update, :destroy]
def set_issue
  @issue ||= params[:id].present? ? Issue.find(params[:id]) : Issue.new
end

# view _form
form_for @issue do |f|
  f.text_field :name
  f.fields_for @issue.comments.new do |ff|
    ff.text_field :content
  end
  f.submit "Save!"
end

# Issue model
class Issue < ActiveRecord::Base
  has_many :comments, as: :commentable
  accepts_nested_attributes_for :comments
