ruby-on-rails – Rails设计自定义注册和登录同一页面问题

>自定义注册设计. (customize devise)
>在注册表单旁边创建一个自定义登录表单. (wiki)

一步步 ：

>创建用于自定义注册的控制器并从默认注册设备继承

# 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

>创建用于自定义会话的控制器并从默认会话设备继承

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

>创建注册视图app / registrations / new.html.erb

将登录和注册表单放入app / registrations / new.html.erb. (注册表旁边看起来像你的项目)

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

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

>覆盖应用程序助手中的设计映射方法

module ApplicationHelper
  def resource_name
    :user
  end

  def resource
    @resource ||= User.new
  end

  def devise_mapping
    @devise_mapping ||= Devise.mappings[:user]
  end
end

>自定义注册设备和会话的路由

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

希望这有帮助！
