设计登录后如何重定向到不同的页面（基于一些参数）？ [英] Devise how to redirect to different page (based on some parameter) after sign in?

问题描述

在我的应用程序中，我有两个不同的登录表单，两个控制器将通过Devise :: SessionsController签名，问题是成功登录（或失败）后，我需要重定向到特定于控制器的不同页面。我该怎么做我目前在我的Devise :: SessionsController中有这个，

  class SessionsController< Devise :: SessionsController 
 def create 
 resource = warden.authenticate！（：scope => resource_name，：recall =>＃{controller_path} #failure）
 return sign_in_and_redirect（resource_name ，资源）
 end 
 
 def sign_in_and_redirect（resource_or_scope，resource = nil）
 scope = Devise :: Mapping.find_scope！（resource_or_scope）
 resource || = resource_or_scope 
 sign_in（scope，resource）除非warden.user（scope）== resource 
 redirect_to dashboard_path 
 end 
 
 def failure 
 redirect_to index_path 
 end 
 end 
  

解决方案

在应用程序控制器

  before_filter：store_location 
 def store_location 
除非params [：controller] ==devise / sessions
 url = #calculate url这里基于您在
会话中传递的params [：token] ：user_return_to] = url 
 end 
 end 
 
 def stored_location_for（resource_or_scope）
会话[：user_return_to] ||超级
结束
 
 def after_sign_in_path_for（资源）
 stored_location_for（资源）|| root_path 
 end 
  

In my application, I have two different login forms from two controller which will both sign_in through the Devise::SessionsController, the problem is after successful sign in (or failure) I need to redirect to different pages that specific to the controller. How can I do this. I currently have this in my Devise::SessionsController, which

class SessionsController < Devise::SessionsController
    def create
        resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#failure")
        return sign_in_and_redirect(resource_name, resource)
      end

      def sign_in_and_redirect(resource_or_scope, resource=nil)
        scope = Devise::Mapping.find_scope!(resource_or_scope)
        resource ||= resource_or_scope
        sign_in(scope, resource) unless warden.user(scope) == resource
        redirect_to dashboard_path
      end

      def failure      
        redirect_to index_path
      end
end

解决方案

In application controller

  before_filter :store_location
  def store_location
    unless params[:controller] == "devise/sessions"
      url = #calculate the url here based on a params[:token] which you passed in
      session[:user_return_to] = url
    end
  end

  def stored_location_for(resource_or_scope)
    session[:user_return_to] || super
  end

  def after_sign_in_path_for(resource)
    stored_location_for(resource) || root_path
  end
