注册wih设计

Question

我有一个社区模型has_many：用户和用户模型belongs_to：社区。

我需要用户注册时可以在同一个过程中创建一个社区，并在注册时分配给此社区。如果没有创建社区，则不应创建该用户。

我应该怎么做？也许为用户创建一个定制的设计控制器...任何想法，将不胜感激。

应用程序/控制器/设计/ registrations_controller.rb

# GET /resource/sign_up 
    def new 
     logger.info "1" 
     build_resource({}) 
     render_with_scope :new 
    end 

# POST /resource 
def create 
    logger.info "2" 
    build_resource 

    if Community.save_both_a_new_user_and_a_new_instance(resource) 
    if resource.active_for_authentication? 
     set_flash_message :notice, :signed_up if is_navigational_format?

Answer 1

是的，当然，我认为你必须自定义设计控制器。

step1。在你的本地控制器设计文件（通过运行其自己的发电机耙任务，或通过手动复制它的控制器到本地文件夹），在这之后，你的文件夹结构应该是这样的：

app/controllers/devise/registrations_controller.rb 
app/views/devise/registrations/new.html.erb 
app/views/devise/registrations/edit.html.erb 

第二步。编辑您的应用程序/控制器/设计/ registrations_controller.rb：

# POST /resource 
def create 
    build_resource 
    if resource.save # change this line of code. 
    if resource.active_for_authentication? 
     redirect_to root_path, :notice => "successfully registered..." 
    else 
     # other code .... 
    end 
    else 
    clean_up_passwords resource 
    respond_with resource 
    end 
end 

改变上面的文件，

if resource.save # change this line of code. 

到：

if Community.save_both_a_new_user_and_a_new_instance(resource) 

第三步。在社区使用交易实施方法：

class Community 
    def Self.save_both_a_new_user_and_a_new_instance(user) 
    Community.transaction do 
     community = Community.new(:name => "new community") 
     user.community = community 
     community.save! 
     user.save! 
    end 
    end 
end 

Answer 2

我重新做了一切，并工作！唯一的东西，我不得不从您的代码更改为：

• 继承社区ActiveRecord的（使用的has_many）和
• 改变自我类方法Self.save_both_a_new_user_and_a_new_instance（用户）self.save_both_a_new_user_and_a_new_instance（用户）。

谢谢!!
