“在此操作中多次调用渲染和/或重定向”在设计上

Question

我正在使用设计并尝试在注册表单后将我的用户重定向到特定模板。

我已经检查了有关 after_inactive_sign_up_path_for 方法的文档，但我收到一个异常说我重定向了两次。

RegistrationsController < Devise::RegistrationsController

def create
    super
    UsersCreateJob.perform_later(resource.id) if resource.persisted?
end

protected

def after_inactive_sign_up_path_for(resource)
   render template: 'devise/registrations/success'
end

Exception

AbstractController::DoubleRenderError in RegistrationsController#create

Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".

据我了解，after_inactive_sign_up_path_for 方法会覆盖来自设计注册控制器的方法并重定向到我的模板，对吗？这个其他模板来自哪里？

Answer 1

after_inactive_sign_up_path_for 并不是要渲染视图。这是将用于重定向的路径。您应该只放置一个动作渲染的路径'devise/registrations/success'。

您看到的错误是由于设计控制器调用了渲染/重定向，然后您也尝试调用它。
