Question

我有一个社区模型，其中包含has_many：users，以及belongs_to：community的用户模型。

我需要在用户注册时在同一过程中创建社区，并在注册时分配给此社区。如果没有创建社区，则不应创建用户。

我该怎么办？也许为用户创建一个自定义设计控制器...任何想法都将不胜感激。

<h3>Cancel my account</h3>

Answer 1

是的，当然，我认为您必须自定义您的Devise Controller。

步骤1。创建本地Devise控制器文件（通过运行自己的生成器rake任务或手动将其控制器复制到本地文件夹），之后，您的文件夹结构应如下所示：

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

步骤2。编辑你的app / controllers / devise / 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

更改上面的文件，

if resource.save   # change this line of code.

到：

if Community.save_both_a_new_user_and_a_new_instance(resource)

步骤3。使用事务在社区中实现该方法：

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

我重新做这一切并且工作!!我必须从您的代码中更改的唯一内容是：

从ActiveRecord继承社区（用于使用has_many）和
将自我类方法Self.save_both_a_new_user_and_a_new_instance（user）更改为self.save_both_a_new_user_and_a_new_instance（user）。

谢谢！
