Application.rb methods not accessible

rubyonrails-talk

For some reason I seem to be unable to call methods defined in application.rb

All controllers are supposed to inherit from application.rb correct?

I have a bit of code that does some filtering and I want it accessible from any controller however when I try to call it, it fails.

show how you've defined it in application.rb and how you're calling from your controller.

application.rb   def desired_columns(model, fields, omit = true)     columns = model.constantize.content_columns.collect do | content_column|       if omit         for field in fields           if content_column.name != field             content_column           end         end       else         for field in fields           if content_column.name == field             content_column           end         end       end     end

    return columns.compact!   end

Here is where I'm calling it this is in a controller:

  def details     @user = session[:user]

    @columns = desired_columns("User", ["salt", "hashed_password"])   end

that looks correct... make sure your application.rb starts with   class ApplicationController < ActionController::Base

and other controllers start with   class MyController < ApplicationController

what version OS/ruby/rails? i'd probably back up my project, nuke ruby and rails and reinstall them.
