Restul Controllers with multiple access points


#1

I’m trying to solve the same problem outlined in this blog post by Tore
Darell. Basically, what’s the best practice for having multiple access
points to a nested resource:

IE:
class User < ActiveRecord::Base
has_many :posts
end

class Category < ActiveRecord::Base
has_many :posts
end

class Post < ActiveRecord::Base
belongs_to :user
belongs_to :category
end

This blog points out one method but I feel like creating a ton of
different
controllers is the cleanest method, any other thoughts?

I would say, as long as there’s more similarities than differences in
the way you retrieve and present posts in the different contexts,
stick to doing it DRY, i.e. one controller and one set of views for
posts, and use private methods in the controller and helper methods in
the view to abstract away the complexity. For example, you could do
something like this in the controller:

class PostsController < ApplicationController
before_filter :find_parent

def index
@posts = @parent ? @parent.posts.find(:all) : Post.find(:all)
end

private
def find_parent
@parent =
if params[:category_id]
Category.find(params[:category_id])
elsif params[:user_id]
User.find(params[:user_id])
end
end
end
