更改新的和编辑的路由答案

【问题标题】：Change routing of new and edit更改新的和编辑的路由

【问题描述】：

我为“帖子”设置了脚手架，并希望使用 ActiveAdmin 来编辑和创建新的。

在我的 routes.rb 文件中，我有这样的帖子设置：

resources :posts

我希望当有人转到“/posts/new”时被重定向到“/admin/posts/new” 编辑也是一样。从 '/posts/:id/edit' 到 '/admin/posts/:id/edit'

如何在更改新路线和编辑路线时保持其他路线不变？

编辑

这是我的“rake 路线”

【解决方案1】：

试试这样的

# config/routes.rb
resources :posts, except: [:new, edit] do
  get 'new' => redirect("/admin/posts/new"), :on => :collection
  get 'edit' => redirect("/admin/posts/:id/edit"), :on => :member
end

PS 请将您的$ rake routes 添加到您的问题中，以使我的代码示例更清晰。

当我将重定向 :id 更改为 %{id} 时，编辑部分运行良好......但我无法让“新”部分正常工作。我不断收到：“ActiveRecord::RecordNotFound in PostsController#show 找不到 id=new 的帖子”....所以我只选择了 Ugis 的答案。谢谢。

【解决方案2】：

get "/posts/new" => redirect("/admin/posts/new")
get "/posts/:id/edit" => redirect("/admin/posts/:id/edit")
resources :posts

【讨论】：

谢谢！新的部分工作得很好。您只需将编辑部分更改为：get "/posts/:id/edit" => redirect("/admin/posts/%{id}/edit")。重定向的“:id”部分必须像这样“%{id}”

【解决方案3】：

也许你可以 redirect_to 在编辑和新方法中。
