Question

在我的应用程序中，控制器之前有代码，它应该在登录后将每种类型的用户重定向到适当的页面。当每种类型的用户注册时，它们应该重定向到根页面，这是相同的退出。当我点击登录或注册按钮时，我会重定向到customer_dashboard而不是登录或注册页面。当我点击退出时，我收到此错误Cannot redirect to nil!，在添加这些重定向方法之前，当我点击每个按钮时，他们会链接到正确的页面进行登录和注册。这段代码有什么问题？为了使这个网站有效，是否有一些逻辑缺少代码？

class ApplicationController < ActionController::Base
    # Prevent CSRF attacks by raising an exception.
    # For APIs, you may want to use :null_session instead.
    protect_from_forgery with: :exception
    before_action :authenticate!

    def after_sign_in_path_for(resource)
        case resource
            when Customer then customer_dashboard_path
            when Vendor  then stored_location_for(:vendors) || vendor_dashboard_path
        end
    end

    def after_sign_out_path_for(resource)
        case resource
            when Customer then root_path
            when Vendor  then stored_location_for(:vendors) || root_path
        end
    end

    def after_inactive_sign_up_path_for(resource)
        case resource
            when Customer then root_path
            when Vendor  then stored_location_for(:vendors) || root_path
        end
    end

  def authenticate!
      if @current_user == current_customer
          :authenticate_customer!
          elsif @current_user == current_vendor
          :authenticate_vendor!
      end
  end

end

所以我添加了skip_before_filter：authenticate！所有4个控制器和路由问题仍然存在。

class Vendors::RegistrationsController < Devise::RegistrationsController
# before_action :configure_sign_up_params, only: [:create]
# before_action :configure_account_update_params, only: [:update]
skip_before_filter :authenticate!
  # GET /resource/sign_up
  # def new
  #   super
  # end

  # POST /resource
  # def create
  #   super
  # end

  # GET /resource/edit
  # def edit
  #   super
  # end

  # PUT /resource
  # def update
  #   super
  # end

  # DELETE /resource
  # def destroy
  #   super
  # end

  # GET /resource/cancel
  # Forces the session data which is usually expired after sign
  # in to be expired now. This is useful if the user wants to
  # cancel oauth signing in/up in the middle of the process,
  # removing all OAuth session data.
  # def cancel
  #   super
  # end

  # protected

  # If you have extra params to permit, append them to the sanitizer.
  # def configure_sign_up_params
  #   devise_parameter_sanitizer.permit(:sign_up, keys: [:attribute])
  # end

  # If you have extra params to permit, append them to the sanitizer.
  # def configure_account_update_params
  #   devise_parameter_sanitizer.permit(:account_update, keys: [:attribute])
  # end

  # The path used after sign up.
  # def after_sign_up_path_for(resource)
  #   super(resource)
  # end

  # The path used after sign up for inactive accounts.
  # def after_inactive_sign_up_path_for(resource)
  #   super(resource)
  # end
end

这是因为before_action :authenticate!因为它在每次操作之前被调用并且您错误地路由了。

我不会想到你的目标是什么，但在进行过滤之前必须先跳过这个，然后再进行登录或注册等操作。

登录，退出并注册无法重定向
