Ruby on Rails - 为自定义视图创建路由

Question

我觉得我已经很接近了，所以我会直奔主题。我创建了一个新的视图文件 (app/views/subjects/screening.html.erb)。这会将新文件放在我用作模板的 edit.html.erb 旁边。我的 edit.html.erb 文件按预期工作，这真的很奇怪，因为我已经为我的新文件复制了逻辑/路由/等，但我没有得到相同的结果。

这令人沮丧。 MVC 很刻薄。

所以这里是页面的链接：

主题/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 %>

“编辑”链接有效，生成此 URL 'localhost:3000/subjects/{:id}/edit'。并且“scr”的链接没有，产生 'localhost:3000/screening.{:id}'。

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'

我是否必须声明一些额外的东西，因为我是手动添加的？任何帮助将不胜感激。谢谢。

Answer 1

我会建议这样的嵌套路由：

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

这应该允许：

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

我可能对命名有点不满意。请务必检查您的路线（rake routes 在 shell 中）。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'

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