Question

我觉得我真的很亲密，所以我会明白这一点。我创建了一个新的视图文件（app / views / subjects / screening.html.erb）。这会将新文件放在edit.html.erb旁边，我将其用作模板。我的edit.html.erb文件按预期工作，这非常奇怪，因为我已经为我的新文件复制了逻辑/路由/等等，而且我没有得到相同的结果。

这令人沮丧。 MVC是卑鄙的。

所以这是指向页面的链接：

受试者/ index.html.erb

  <% @subjects.each do |sub| %>
    <tr>
      <td><%= link_to "edit", edit_subject_path(sub) %></td>
      <td><%= link_to "scr", screening_path(sub) %></td>
      <td><%= sub.subject_id %></td>
      <td><%= sub.study_site == 1? "Seattle" : sub.study_site == 2? "Portland" : "nil"%></td>
      <td><%= sub.treatment_group %></td>
    </tr> 
  <% end %>

如果“编辑”链接有效，则生成此网址“localhost：3000 / subjects / {：id} / edit”。并且“scr”的链接没有，生成'localhost：3000 / screening。{：id}'。

的routes.rb

  resources :users
  resources :sessions, only: [:new, :create, :destroy]
  # resources :subjects, only: [:new, :create, :destroy]
  resources :subjects



  match '/signup', to: 'users#new'
  match '/signin', to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', via: :delete
  match '/edit', to: 'users#edit'

  root to: 'static_pages#home'

  match '/help', to: 'static_pages#help'
  match '/about', to: 'static_pages#about'
  match '/contact', to: 'static_pages#contact'

  match '/subjects', to: 'subjects#show'
  match '/newsubject', to: 'subjects#new'
  match '/subjects', to: 'subjects#index'
  match '/showsubject', to: 'subjects#show'
  match '/editsubject', to: 'subjects#edit'
  match '/screening', to: 'subjects#screening'

我是否必须申报额外的东西，因为我手动添加了它？任何帮助将不胜感激。感谢。

我会建议像这样的嵌套路线：

resources :subjects do 
  match '/screening', to: 'subjects#screening', as: :screening
end

应该允许：

link_to "scr", subject_screening_path(sub)
#> /subjects/1/screening

我的命名可能有点偏差。请务必检查您的路线（shell中的rake routes）。另外，删除：

  match '/subjects', to: 'subjects#show'
  match '/newsubject', to: 'subjects#new'
  match '/subjects', to: 'subjects#index'
  match '/showsubject', to: 'subjects#show'
  match '/editsubject', to: 'subjects#edit'
  match '/screening', to: 'subjects#screening'

这些路线是使用resources :subjects自动生成的，但默认情况下它们的路径不同。
