覆盖设计注册创建方法 [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

我有传递 tags 参数的复选框，并且我已经在服务器日志中验证了正在传递 tags 参数.但是，当我在控制台中调用 @user.tag_list 时，我只会得到一个空白响应 [] .

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 [] .

我觉得问题出在我对devise的create方法的操作上.我没有在任何地方明确设置@user，但不确定如何使用 Devise 设置它.有谁知道在使用devise时如何设置特定字段?

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

供将来在搜索如何覆盖设计方法时发现此问题的任何人参考，大多数设计方法都接受一个块，因此这样的事情应该可以作为嗯:

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
