具有CanCanAdapter的ActiveAdmin导致仪表板上的无限重定向 [英] ActiveAdmin with CanCanAdapter causing infinite redirect on dashboard

问题描述

在ActiveAdmin 0.6.0中使用CanCan适配器时。我有资源在工作，授权正在工作。但是，当我进入 / admin 的根ActiveAdmin页面时，它将重定向到 / admin 并永远继续下去。

When using the CanCan adapter in ActiveAdmin 0.6.0. I have a resource working and authorization is working. However, when I go to /admin, the root ActiveAdmin page, it redirects to /admin and continues this forever.

推荐答案

如果用户无权访问页面，则ActiveAdmin将重定向到仪表板。如果用户无权访问仪表板，则会导致无限重定向。

If the user does not have access to a page, ActiveAdmin redirects to the Dashboard. If the user doesn't have access to the dashboard, this results in an infinite redirect.

解决方案是使用户能够读取仪表板页面。将其放置在能力模型对象中：

Solution is to give the user the ability to read the dashboard page. Place this in the ability model object:

can :read, ActiveAdmin::Page, :name => "Dashboard"

在授权适配器文档，但无限重定向似乎是由ActiveAdmin中的错误。它既没有引发CanCan :: AccessDenied，也没有向用户显示消息。至少，它应该在开发中显示一条消息，以帮助解决此问题。但是目前还没有。

This is mentioned in the authorization adapter documentation, but the infinite redirect seems to be caused by a bug in ActiveAdmin. It is neither raising a CanCan::AccessDenied, nor displaying an message to the user. At the least, it should display a message in development to help troubleshoot this issue. But it does not currently.
