将根目录重定向到 /admin

Question

我有一个非常奇怪的问题，有一段时间我可以正常工作，但现在总是失败。

我希望 /admin 后缀成为我的应用程序的根页面。

我试过了：

root to: redirect('/admin')
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)

这个：

  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  get '/', to: redirect('/admin')

还有这个（没有运气）：

  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  root to: 'admin/dashboard#index'

我认为最后一个选项是 sn-p 昨天工作，但我不确定。

你建议怎么做？有什么想法吗？

你几乎做对了！

您将根路径设置为：root to: redirect('/admin')

这样，您还必须明确声明要路由到的路由，如下所示：match '/admin', to: 'admin/dashboard#index', via: :get

这样，你的根路径每次调用时都会自动调用后面的路由和控制器。

澄清一下，您的设置将如下所示：

TestActiveAdmin::Application.routes.draw do 
  root to: redirect('/admin')
  match '/admin', to: 'admin/dashboard#index', via: :get

  ActiveAdmin.routes(self)

  devise_for :admin_users, ActiveAdmin::Devise.config

  ...
end

然后您可以在 Rails 控制台中验证：rake routes | grep root

您应该会看到如下内容： root /admin {:controller => 'admin/dashboard, :action => 'index'
