Activeadmin不注销，当我点击“注销”

问题描述：

我下面从有关安装activeadmin的railscast的说明。在安装时，我得到了两个错误 -Activeadmin不注销，当我点击“注销”

1）args作为sign_in数量无效 - 所以我改名为我sign_in方法sign_in_user并修复了这个问题。

然后

2）args作为signed_in的无效数？ - 所以我重新命名了我的signed_in？方法is_signed_in？并解决了这个问题。

现在一切似乎只是当我点击注销按钮activeadmin工作，它说：“登出成功”，但注销按钮仍然在右上角，并没有记录我出去。

我加了这两样东西，每建议我active_admin.rb文件从人有类似问题：

config.logout_link_path = :destroy_admin_user_session_path

和

config.logout_link_method = :delete

但仍没有运气。这里是我的耙路线：

我在想什么？谢谢！

一旦你改变了它的配置文件，你有没有“重启”你的rails应用程序？
你的routes.rb是什么样的？我想知道你是否有2个devise_for语句，例如
```
devise_for :admin_users, ActiveAdmin::Devise.config 
#... other routes 
devise_for :users 
```
如果是这样，请删除其中的1个。

确保如果注销链接看起来象下面这样：

<a href="https://*.com/users/sign_out" data-confirm="Are you sure？" data-method="delete" rel="nofollow">Logout</a>

答

我有，你都面临着同样的问题。我不能在你的代码中看到，你有sign_in和signed_in？方法，但我怀疑你可能会把它们放在SessionsHelper类或类似的地方，并且那个帮助器就像这样包含在ApplicationController中？

class ApplicationController < ActionController::Base 
    protect_from_forgery 
    include SessionsHelper 
...

看来ActiveAdmin也实现了这些方法，并覆盖它们在SessionsHelper沉船它。你走在正确的道路上，差不多在那里！还有一个方法，你可能需要重命名，然后你做：

SIGN_OUT

重命名一个过，那么你应该能够既登录和退出，就像以前一样。祝你好运！

答

我在我的SessionsHelper改变我SIGN_OUT方法的名称解决它。

def sign_out_user 
    current_user.update_attribute(:remember_token, 
           Adult.digest(Adult.new_remember_token)) 
    cookies.delete(:remember_token) 
    self.current_user = nil 
end

然后我不得不改变我SessionsController破坏方法来匹配

def destroy 
    sign_out_user ###CHANGE HERE 
    redirect_to root_url 
end

此外，如果您使用的是你的意见的任何地方的方法。您需要更改它，以便它与新的方法名称相匹配。

答

对于设计的用户：

在/config/initializers/active_admin.rb

ActiveAdmin.setup do |config| 
    config.logout_link_path = :destroy_user_session_path 
    config.logout_link_method = :delete

测试更改之前重新启动服务器。
