虚拟属性与Rails中的Devise 4 [英] Virtual attributes with Devise in Rails 4

问题描述

我的用户模型没有一个：name 字段，但我想要包含一个：name 字段我的注册表单将用于在 after_create 中创建另一个模型的记录。

My User model doesn't have a :name field but I want to include a :name field in my sign up form which will be used to create a record of another model in an after_create.

class User < ActiveRecord::Base
  after_create :create_thing

private
  def create_thing
    @thing = Thing.new
    @thing.name = <here's where I need help>
    @thing.save!
  end
end

如何从注册表单中获取名称

How can I get the name from the sign up form?

推荐答案

在您的模型中，添加attr_accessor作为名称

In your model add attr_accessor for name

attr_accessor :name

这将允许您将其添加到表单中使用它在您的after_create

This will allow you to add it to a form and use it to generate the proper data in your after_create
