Question

I’m using devise for my user registrations and I’d like to have a separate edit path for user’s to change/update their passwords. I’ve pulled the devise registrations views out and created a separate registrations controller like described in Railscast 236

I’ve tried creating a new action called change_password in the registrations controller but when I try to set the route with match ‘/change_password’, to => ‘registrations#change_password’ I get an AbstractController::Actions Not Found

registrations controller

class RegistrationsController < Devise::RegistrationsController

def create
  super
  session[:omniauth] = nil unless @user.new_record?
 end

 def destroy
   resource.destroy 
   set_flash_message :notice, :destroyed
   sign_out_and_redirect(self.resource)
 end

 def change_password
   render_with_scope :edit
 end

private
  def build_resource(*args)
   super
   if session[:omniauth]
     @user.apply_omniauth(session[:omniauth])
     @user.valid?
   end
 end

routes.rb

  match 'auth/:provider/callback' => 'authentications#create'
  resources :authentications

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




  resources :posts do
      member do
      get :likers
      end
       collection do
        get :search
      end
  end  

  resources :relationships, :only => [:create, :destroy]
  resources :appreciations, :only => [:create, :destroy]

   root :to => "pages#home"

  match '/contact', :to => 'pages#contact'
  match '/about',   :to => 'pages#about'
  match '/help',    :to => 'pages#help'
  match '/blog',    :to => 'pages#blog'


  resources :users do
     member do
     get :following, :followers, :likes
     end
     resources :collections
 end
end

views/registrations/change_password.html.erb

<h2>Edit <%= resource_name.to_s.humanize %></h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :validate => true,
                   :html => { :method => :put }, :html => {:multipart => true}) do |f| %>  
   <%= devise_error_messages! %> 
  <p><strong>To change password, otherwise leave blank.</strong></p>
  <p><%= f.label :current_password %> <i>(leave blank if you don't want to change it)</i><br />
  <%= f.password_field :current_password %></p>
  <p><%= f.label :password, "New password" %> <br />
  <%= f.password_field :password %></p>
  <p><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></p>
  </div><br />
  <p><%= f.submit "Update" %></p>
<% end %>

Try to pass match .. in the block of devise_for helper:

devise_for :users, :controllers => {:registrations => 'registrations'} do
  match '/change_password', to => 'registrations#change_password'
end
