Rails Devise Custom Registration and Login at the same page issues

Question

In my Ruby app, I am using the \'devise\' gem for authentication but I want to customize the views, generate the devise views after customizing each of them and saving them

Answer 1

Actually, your question is the same as this question, but I'll explain a little bit and I'm try to do it.

1. Customize registration devise. (customize devise)
2. Make a custom login form beside on registration form. (wiki)

---

Step by step :

1. Create controller for customize registration and inherit from default registration devise

   # customize registration controller
   class RegistrationsController < Devise::RegistrationsController
     layout 'login'
     skip_before_filter :require_no_authentication
     before_filter :resource_name
   
     def resource_name
       :user
     end
   
     def new  
       @user = User.new
     end
   
     def create
       @user = User.new(params[:user])
       # another stuff here
     end
   end
   

2. Create controller for customize session and inherit from default session devise

   # customize session controller
   class SessionsController < Devise::SessionsController
     def create
       super
     end
   end
   

3. Create registration views app/registrations/new.html.erb

   Put login and registration form into app/registrations/new.html.erb. (beside on registration form looks like your project)

   <%= form_for(resource, :as => resource_name, :url => user_session_path(resource_name)) do |f| %>
   <%# another stuff here %>  
   <% end %>
   
   <%= form_for(resource, :as => resource_name, :url => user_registration_path(resource_name)) do |f| %>
   <%# another stuff here %>
   <% end %>
   

4. Override devise mapping method in application helper

   module ApplicationHelper
     def resource_name
       :user
     end
   
     def resource
       @resource ||= User.new
     end
   
     def devise_mapping
       @devise_mapping ||= Devise.mappings[:user]
     end
   end
   

5. Route for customize registration devise and session

   devise_scope :user do
     # using login path for registration
     get '/login' => 'registrations#new', :as => :new_user_registration
     post '/signup' => 'registrations#create', :as => :user_registration
     post '/signin' => 'sessions#create', :as => :user_session
   end
   

Hope this help!
