控制器 Rails 5 不需要调用Before_Action

Question

我目前正在尝试重定向user.account_delinquent = true的用户帐户。问题是，即使帮助程序方法处于活动状态，该帐户仍能够访问测试控制器。

我的控制器包含带有before_action :account_delinquency的ApplicationHelper，但该方法拒绝触发。

如果current_user.account_delinquent == true，如何正确设置我的account_delinquency帮助程序方法来触发重定向？

我的代码如下：

magazines_controller.rb

class MagazinesController < ApplicationController
include ApplicationHelper
before_action :account_delinquency
def index
@magazines = Magazine.all
end
end

application_helper.rb

def account_delinquency
if user_signed_in? || employer_signed_in?
redirect_to update_account_index_path, alert: 'We were unable to charge your account' if current_user.account_delinquent == true || current_employer.account_delinquent == true
end
end

Answer 1

尝试在ApplicationController中定义account_delinquency，而不是在ApplicationHelper中定义。我总是在控制器中先于操作，从不在帮助程序中。

Answer 2

我设法通过将user_session同步到用户变量本身来使帮助程序方法工作。因为，此方法将仅用于登录成员。

application_helper.rb

def account_delinquency
@current_user ||= User.find_by_session(session[:user_id])
redirect_to update_account_index_path, alert: 'We were unable to charge your account' if @current_user.account_delinquent
end

控制器.rb

class MagazinesController < ApplicationController
include ApplicationHelper
before_action :account_delinquency
end
