Question

在我的rails项目中，我运行rake routes并获得以下输出：

 Prefix Verb   URI Pattern                                              Controller#Action

                       PATCH  /obelisk/callflows/:callflow_id/nodes/:id(.:format)      obelisk/nodes#update
                       PUT    /obelisk/callflows/:callflow_id/nodes/:id(.:format)      obelisk/nodes#update
                       DELETE /obelisk/callflows/:callflow_id/nodes/:id(.:format)      obelisk/nodes#destroy

                       POST   /obelisk/callflows(.:format)                             obelisk/callflows#create
  new_obelisk_callflow GET    /obelisk/callflows/new(.:format)                         obelisk/callflows#new

      obelisk_callflow GET    /obelisk/callflows/:id(.:format)                         obelisk/callflows#show
                       PATCH  /obelisk/callflows/:id(.:format)                         obelisk/callflows#update
                       PUT    /obelisk/callflows/:id(.:format)                         obelisk/callflows#update
                       DELETE /obelisk/callflows/:id(.:format)                         obelisk/callflows#destroy

我有一个html.slim文件，用于显示所有呼叫流程（即方尖碑/ nodes＃index）。在此文件中，我想添加一个按钮以显示每个调用流的节点（即，将该按钮连接到obelisk_callflow_nodes GET /obelisk/callflows/:callflow_id/nodes）

我尝试了= link_to 'Nodes', obelisk_callflow_nodes_path(callflow_id: c.id), method: :get, class: 'btn btn-primary'，其中c是一个调用流对象。我检查了c是否是我想要的，因为我已经正确渲染了c.name。但是，出现以下错误：

undefined method obelisk_callflow_nodes_path'for＃<＃：0x00007fb3d5abebc8>`

我检查了我的Obelisk :: NodesController是否具有索引方法

Answer 1

我更改了路由，以便不再使用namespace obelisk，因此路由不会以/ obelisk /开头。这样可以解决问题。我知道这可能不是最好的解决方案，但在这种情况下，它已达到我的项目目的。

html slim link_to未定义方法错误
