设计如何添加登录检查自定义会话控制器？ [英] Devise how to add signed in check in custom session controller?

问题描述

我正在尝试使用Devise的控制器帮助程序signed_in？检查用户是否已经sign_in，如果是，那么我想重定向到一个特定的页面。

我已经尝试过这个，但是signed_in？方法总是返回true，我该如何使这项工作？

  class SessionsController< Devise :: SessionsController 
 def new 
 redirect_to root_url 
 end 
 
 def create 
如果signed_in？（resource_name）
 redirect_to其中_-_ want_to_url 
 else 
 resource = warden.authenticate！（：scope => resource_name，：recall =>＃{controller_path} #failure）
 
 return sign_in_and_redirect（resource_name，resource ）
 end 
 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 
 return render：json => {：success => true，：redirect => stored_location_for（scope）|| after_sign_in_path_for（resource）} 
 end 
 
 def failure 
 return render：json => {：success => false} 
 end 
 
 end 
  

解决方案

您是否尝试过如果user_signed_in？

现在，我真的不知道你是什么尝试完成，但我不会在控制器中定义我的路由。我会这样做：

 ＃config / routes.rb 
认证：user do 
 root：to => where_I_want_to_url 
 end 
 root：to => 'welcome＃index'
  

I am trying to use Devise's controller helper method signed_in? to check if a user already signed_in, if yes then I want to redirect to a specific page.

I have tried this, but the signed_in? method always return true, how can I make this work?

class SessionsController < Devise::SessionsController
  def new
    redirect_to root_url 
  end

  def create
    if signed_in?(resource_name)
      redirect_to where_-_want_to_url
    else  
      resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#failure")

      return sign_in_and_redirect(resource_name, resource)
    end
  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
    return render :json => {:success => true, :redirect => stored_location_for(scope) || after_sign_in_path_for(resource)}
  end

  def failure      
    return render :json => { :success => false }
  end

end

解决方案

Have you tried if user_signed_in?

Now, I'm really not sure what you are trying to accomplish but I wouldn't define my routing like that in the controller. I'd do something like this:

# config/routes.rb
authenticated :user do
  root :to => where_I_want_to_url
end
root :to => 'welcome#index'
