Ruby on Rails：自定义设计注册控制器，要求创建操作 [英] Ruby on Rails: Custom Devise Registration Controller, Asking For Create Action

问题描述

我有一个自定义注册控制器，但是我不想覆盖设计中的创建操作。当我尝试注册用户时，我会收到以下错误：

 未知操作
 
操作创建找不到Devise :: RegistrationsController 
  

是否要求它，因为我有一个自定义注册控制器？如果是这样，这是否意味着我需要复制我不超过这些的所有动作： https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb

我的路线：

 
 code> 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 
  

这是我设计的注册控制器

  class Devise :: RegistrationsController< DeviseController 
 
 skip_before_filter：require_no_authentication 
 
 def edit 
 @user = User.find（current_user.id）
 @profile = Profile.new 
 end 
 
 def update 
＃当密码留空时需要设置表单提交
如果params [：user] [：password] .blank？ &安培;&安培; PARAMS [：用户] [：password_confirmation] .blank？ 
 params [：user] .delete（：password）
 params [：user] .delete（：password_confirmation）
 end 
 
 @user = User.find current_user.id）
如果@ user.update_attributes（params [：user]）
 set_flash_message：通知，更新
＃登录用户绕过验证，以防其密码更改
 sign_in @user，：bypass => true 
 redirect_to after_update_path_for（@user）
 else 
呈现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 
  

这是注册表单：

 <％= form_for（resource，：as => resource_name，：url => registration_path（resource_name））do | f | ％GT; 
 ... 
< div> 
<％= button_tag：type => ：submit，：class => btn btn-large btn-inversedo％> 
注册
<％end％> 
< / div> 
 ... 
<％end％> 
  

解决方案

您的注册控制器继承自错误的类：DeviseController
它是注册的基类，没有创建方法，您的自定义Devise :: RegistrationsController类（它只有编辑和更新方法）也会导致错误。

为了创建自己的自定义注册控制器，对于回溯到原始设计方法的用户，我建议您执行以下操作：

1.创建用户文件夹在控制器文件夹

2.创建有registrations_controller.rb文件，并在其中定义类：

 用户： ：注册控制器< Devise :: RegistrationsController 
  

并覆盖任何操作（编辑和更新）

3.通知routes.rb文件有关更改：

  devise_for：users，：controllers => {注册：'用户/注册'} 
  

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 %>

解决方案

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' }
