Devise NoMethodError in Devise::Sessions#create

I have a small problem that I cant track down. Basically I have my application controller and in my application controller I have a method: 

def getCategories
  @categories = Category.all
end

Nothing special I have a sidebar partial view that I load in to my main layout. This partial is loaded by almost all controllers/actions with few exceptions so to avoid always declaring this method i simply have a before_filter to invoke this method so that @categories are automatically included in all controllers.

The problem now is when I attempt to login using devise sign in view it tries to redirect me to root however for some reason the @categories are not included and in turn throw this exception: 

NoMethodError in Devise::Sessions#create

Which is confusing because according to devise documentation if you set root :to => 'home#index' as in my case after processing user login user should be redirected to root which points to home controller which should due to before_filter include the @categoires variable.

What am I doing wrong here ?

Maybe you can try adding a new controller "Registrations" and add your method:

class RegistrationsController < Devise::RegistrationsController

   def getCategories
      @categories = Category.all
   end

end

then Modify config/routes.rb to use the new controller

Modify your devise_for line in routes.rb to look like the below.

devise_for :users, :controllers => { :registrations => "registrations" }

replace root :to => 'home#index' with 

  devise_scope :user do
    match "/", to: "devise/registrations#new", via: 'get'
  end
