Question

My devise set up was working fine before, but now, for some reason, whenever I try to sign up a new user, it tries to call users#create instead of registrations#create. I think it must be a problem with my routes.rb file. I recently added a new resource, “preferences”, to my application, so the routing might be wonky:

Indexer2::Application.routes.draw do
  resources :preferences

  get "home/index"

  resources :posts
  resources :users

  devise_for :users, :controllers => {:registrations => 'registrations', :invitations => 'invitations'}, :except => [:show] do
    get "/signup" => "devise/registrations#new", :as => 'user_signup'
    get '/logout' => 'devise/sessions#destroy', :as => 'user_logout'
    get '/login' => "devise/sessions#new", :as => 'user_login'
  end 

  match '/welcome' => 'pages#welcome'

  resources :preferences, :except => [:destory, :edit, :create, :new, :index, :show]  do 
    collection do
      post "make_feed_preference"
      post "change_preference"
    end
  end

  root :to => "home#index"

end

Your UsersController should have create method.
If you don’t want to write your own registration logic just do inheritance from Devise::RegistrationsController < DeviseController:

 controller UsersController < Devise::RegistrationsController
      #....
 end

This will include default Devise methods.
