Question

我正在尝试创建一个名为Snapshot的新资源，以整合可能应该是他们自己的资源的一些操作，而不是使ProjectsController混乱。我确定我已经正确设置了所有内容，但Rails并不认识这条路线。

这里是我的routes.rb的相关摘录：

resources :projects do
  resources :snapshots, only: [:create, :update]
end

当我rake routes运行时，它显示正常：

project_snapshots POST     /projects/:project_id/snapshots(.:format)                                          snapshots#create
 project_snapshot PATCH    /projects/:project_id/snapshots/:id(.:format)                                      snapshots#update
                  PUT      /projects/:project_id/snapshots/:id(.:format)                                      snapshots#update

但是在rails控制台中，我并不高兴：

r = Rails.application.routes
=> #<ActionDispatch::Routing::RouteSet:0x007faa06b5b730>

r.recognize_path "/projects/1234/snapshots"
ActionController::RoutingError: No route matches "/projects/1234/snapshots"
    from /Users/merus/.rbenv/versions/2.2.5/lib/ruby/gems/2.2.0/gems/actionpack-4.2.0/lib/action_dispatch/routing/route_set.rb:840:in `recognize_path'

    from bin/rails:4:in `require'
    from bin/rails:4:in `<main>'

我尝试过更换资源＆＃39;与资源＆＃39;以防万一不起作用;没有骰子。这里有什么问题？

recogn_path默认为＆＃34; GET＆＃34;对于HTTP方法。您还没有使用GET方法定义快照的任何路由。尝试在传入的环境中指定HTTP方法：

r.recognize_path "/projects/1234/snapshots", method: "POST"

Rails路由未找到，但存在于rake路由中
