Controller inheritance use case for heimdallr-resource

controller_inheritance_example.rb

# Let's say we have a blog app. A blog post has several child resources (comments, tags,
# etc.). The controllers for each of these resources share the same layout. Here's one
# way we could do it:

class BasePostsController < ApplicationController
  include Heimdallr::Resource

  load_and_authorize_resource :resource => :post

  # We could have a before_filter here that sets some instance variables for the layout
  # based on the loaded @post.
end

class PostCommentsController < BasePostsController
  load_and_authorize_resource :resource => :comment, :through => :post

  def index
    # ...
  end

  # ...
end

class PostTagsController < BasePostsController
  load_and_authorize_resource :resource => :tags, :through => :post

  def index
    # ...
  end

  # ...
end

# And so on for the other child controllers.

# This way we have extracted the common code into the base controller class.
