什么是devise authenticate_user的代码？生成后为：用户 [英] What is code for devise authenticate_user! after generated for :user

问题描述

我意识到 authenticate_user！是未明确定义，但是我想知道典型的应用程序（名为 User 的模型的身份验证），那么方法看起来像。我需要知道，所以我可以稍微修改一下。

I realize that authenticate_user! is not explicitly defined in the gem files, but I am wondering for the typical app (authentication on model named User), what would the method look like. I need to know so that I can modify it slightly.

推荐答案

我相信你链接到自己的答案，它定义的方法是

I believe you linked to your own answer, the method it defines is

def authenticate_#{mapping}!(opts={})
  opts[:scope] = :#{mapping}
  warden.authenticate!(opts) if !devise_controller? || opts.delete(:force)
end

如果我们替换真正的类，您的案例用户，它看起来像：

Which if we substituted the true class, in your case User, it would look like:

def authenticate_user!(opts={})
  opts[:scope] = :user
  warden.authenticate!(opts) if !devise_controller? || opts.delete(:force)
end

所以它真的要求监管者是认证逻辑的大部分位置。

So it really calls out to warden and that is where the bulk of the authentication logic lies.

对于典型的Rails应用程序， authenticate_user！方法将在 ApplicationController 中定义为 instance_method 。

For a typical Rails application, The authenticate_user! method will be defined as an instance_method on ApplicationController.
