Rails controller view path and lookup context prefixes

rails_controller.rb

# While having issues with to_partial_path on a view model giving inconsistent results under differing name spaces of controllers
# I use the below to see that the look up path and view paths were on an controller and modify.
# I've never put the below into production. This is merely something I found while experimenting.
# To sort my issue I used the prefixes avaialable and changed name spacing to give correct behaviour

class SomeController < ApplicationController
 
 # Prepending (or appending) the view path allows you to add the location of view files
  
 before_filter :prepend_view_paths

   def prepend_view_paths
    prepend_view_path "app/views/backoffice"
   end
  
  # the look up context prefix is used as the prefix for to_partial_path on views. You can add to this with the below. 
  # Be aware it will affect all of your applications lookup_contexts so you need to clear

  def index
    lookup_context.prefixes.prepend 'backoffice'
  end
