重写设计注册创建方法 [英] Overriding Devise Registration Create Method

问题描述

我想在创建用户时专门设置一个字段。我有

I want to specifically set a field when a user is created. I have

class RegistrationsController < Devise::RegistrationsController
  def create
    super
    @user.tag_list = params[:tags]
  end
end

我有复选框传递tags参数，我已经在服务器日志中验证了tags参数正在传递。但是，当我在控制台中调用@ user.tag_list时，我只得到一个空白的回复 [] 。

I have check boxes that pass the tags parameter and I have verified in the server logs that the tags parameter is being passed. However, when I call @user.tag_list in the console I just get a blank response [] .

我觉得问题在于我操纵的创造方法的设计。我没有明确地将@user设置在任何地方，但不知道如何使用Devise进行设置。有没有人知道如何在使用devise时设置一个特定的字段？

I feel that the problem lies in my manipulating of the create method of devise. I have not explicitly set @user anywhere but am not sure how to set it using Devise. Does anyone know how to set a specific field when using devise?

推荐答案

为了覆盖设计方法，大多数Devise方法接受一个块，所以这样的东西也应该也是这样：

For future reference for anyone who finds this while searching for how to override devise methods, most of the Devise methods accept a block, so something like this should work as well:

class RegistrationsController < Devise::RegistrationsController
  def create
    super do
        resource.tag_list = params[:tags]
        resource.save
    end
  end
end
