ruby-on-rails - 为什么“respond_with”不执行失败的设计认证？

Question

成功验证后，我可以这样覆盖respond_with：

class SessionsController < Devise::SessionsController

  def respond_with(resource, *)
    if user_signed_in?
      redirect_to root_path
    end
  end

end

但是，当身份验证失败时——假设密码不正确——我在设计中respond_with的覆盖SessionsController不会被调用。我知道，对于失败的身份验证， Devise 然后调用Devise::SessionsController#new。但是，在该DeviseController#new方法结束时respond_with被调用。

所以我的问题是：

1) 为什么在Devise::SessionsController#create中认证成功时respond_with我的覆盖成功执行？SessionsController

2) 为什么我在身份验证失败时对我的覆盖没有成功respond_with执行？控制器操作以相同的方法完成SessionsControllerDevise::SessionsController#createDevise::SessionsController#newrespond_withDevise::SessionsController#create
