在 Ruby on Rails 中链接模型 [英] Linking models in Ruby on Rails

问题描述

我正在构建一个 Rails 应用，我想连接两个模型.

I"m building a Rails app, and there are two models that I want to connect.

有一个称为用户"的模型来处理用户身份验证，例如用户名和密码数据.然后是一个称为个人资料"的模型，其中包含一个人的位置、描述等.

There's a model called "users" that handles user authentication, e.g. username and password data. Then there's a model called "profiles" that has a person's location, description, etc, etc.

我想链接模型，以便每个用户有一个个人资料.我真的不知道该怎么做.有人介意分享一些关于如何做到这一点的见解吗?

I want to link the models so that there's one profile per user. I really don't know how to do this. Anyone mind sharing some insight on how this can be done?

推荐答案

查看 rails 协会基础知识

你的协会看起来像

class User < AR:Base
  has_one :profile
end

class Profile < AR:Base
  belongs_to :user
end

哦，表配置文件必须有一个 user_id 列，其中包含用户的外键.

oh, the table profiles must have a user_id column with the foreign key to the user.
