ruby-on-rails - 修改 before_action

Question

我的用户模型中有一个 admin:boolean 字段，并且希望能够在用户是管理员之前检查我的 Controller ，然后才能编辑任何内容。

如何修改 before_action :authenticate_user!, only: [:edit] 以检查用户是否为管理员？

Answer 1

您可以添加另一个将在 authenticate_user 之后调用的 before 操作!检查当前用户是否有管理员权限。

class YourController
  # first call authenticate_user! to check if user is signed in
  before_action authenticate_user!, only: [:edit]
  # if user is signed (current_user exist), check if he is admin
  before_action authenticate_admin!, only: [:edit]

  def authenticate_admin!
    # check if current user is admin
    unless current_user.admin
      # if current_user is not admin redirect to some route
      redirect_to 'some_public_route'
    end
    # if current_user is admin he will proceed to edit action
  end
end
