Rails 设计：验证两个模型中的任一个

Question

我正在构建 Rails 具有三种设计模型的应用程序：管理员、教师、学生。我想创建一个管理员和教师可以访问的页面。

我知道如何创建一个角色的用户可以访问的页面。喜欢

before_action :authenticate_model!

但是我想查看管理员或老师的身份验证怎么办？

自动重定向路径可以固定一个。例如，如果用户在未登录的情况下访问了该页面，则该用户将被重定向到带有管理员超链接的教师登录页面。

有什么想法吗？

我想你可以使用 devise_group 选项。

示例：

inside BlogsController (or any other controller, it doesn't matter which):
  devise_group :blogger, contains: [:user, :admin]

Generated methods:
  authenticate_blogger!  # Redirects unless user or admin are signed in
  blogger_signed_in?     # Checks whether there is either a user or an admin signed in
  current_blogger        # Currently signed in user or admin
  current_bloggers       # Currently signed in user and admin

Use:
  before_action :authenticate_blogger!              # Redirects unless either a user or an admin are authenticated
  before_action ->{ authenticate_blogger! :admin }  # Redirects to the admin login page
  current_blogger :user                             # Preferably returns a User if one is signed in
