Ruby on Rails: Custom Devise Registration Controller, Asking For Create Action

Question

I have a custom registration controller, but I don't want to override a create action from devise. When I try to sign up a user, I get this error:

Unknown action

The action 'create' could not be found for Devise::RegistrationsController

Is it asking for it because I have a custom registration controller? If so, does that mean I need to copy all the actions that I'm not overriding from here: https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb

Or its because there's something wrong with my application?

My routes:

  devise_for :user, :controllers => { :registrations => "devise/registrations" }, :skip => [:sessions] do 
    get 'signup' => 'devise/registrations#new', :as => :new_user_registration 
    post 'signup' => 'devise/registrations#create', :as => :user_registration 
  end

This is my devise registration controller

class Devise::RegistrationsController < DeviseController

  skip_before_filter :require_no_authentication

  def edit
    @user = User.find(current_user.id)
    @profile = Profile.new
  end 

  def update
    # required for settings form to submit when password is left blank
    if params[:user][:password].blank? && params[:user][:password_confirmation].blank?
        params[:user].delete(:password)
        params[:user].delete(:password_confirmation)
    end

    @user = User.find(current_user.id)
    if @user.update_attributes(params[:user])
      set_flash_message :notice, :updated
      # Sign in the user bypassing validation in case his password changed
      sign_in @user, :bypass => true
      redirect_to after_update_path_for(@user)
    else
      render "edit"
    end

  end


  protected
    def after_update_path_for(resource)
      user_path(resource)
    end

    def after_sign_up_path_for(resource)
      user_path(resource)
    end

end

This is the registration form:

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
 ... 
  <div>
    <%= button_tag :type => :submit, :class => "btn btn-large btn-inverse" do %>
    Sign up
    <% end %>
  </div>
...
<% end %>

Your controller of registration inherits from the wrong class: DeviseController It is a base class for a registration and has no "create" method, and so does your custom Devise::RegistrationsController class (it has only edit and update methods) - it incurs the error.

In order to create your own custom registration controller for users with fallback to the original devise methods, I suggest you do the following:
1. create "users" folder in controllers folder
2. create there registrations_controller.rb file, and define class there:

Users::RegistrationsController < Devise::RegistrationsController

and override any actions ("edit" and "update")
3. inform the "routes.rb" file about changes:

  devise_for :users, :controllers => { registrations: 'users/registrations' }
