ruby - 尝试查看“已发送”消息时，没有路由匹配 {:action=>"show", :controller=>"users"}

Question

我快到了，我正在尝试找出 simple_private_messages 插件的其余部分。有谁知道我该如何解决这个问题？

这是我的 rake 路由输出

delete_selected_user_messages POST       /users/:user_id/messages/delete_select
ed(.:format)    messages#delete_selected
                 user_messages GET        /users/:user_id/messages(.:format)
                messages#index
                               POST       /users/:user_id/messages(.:format)
                messages#create
              new_user_message GET        /users/:user_id/messages/new(.:format)
                messages#new
             edit_user_message GET        /users/:user_id/messages/:id/edit(.:fo
rmat)           messages#edit
                  user_message GET        /users/:user_id/messages/:id(.:format)
                messages#show
                               PUT        /users/:user_id/messages/:id(.:format)
                messages#update
                               DELETE     /users/:user_id/messages/:id(.:format)
                messages#destroy
                         users GET        /users(.:format)
                users#index
                               POST       /users(.:format)
                users#create
                      new_user GET        /users/new(.:format)
                users#new
                     edit_user GET        /users/:id/edit(.:format)
                users#edit
                          user GET        /users/:id(.:format)
                users#show
                               PUT        /users/:id(.:format)
                users#update
                               DELETE     /users/:id(.:format)
                users#destroy

这是我的 routes.db

  resources :users do
             resources :messages do
               collection do
                 post :delete_selected
               end
             end
           end



  ActiveAdmin.routes(self)

  devise_for :admin_users, ActiveAdmin::Devise.config

  resources :users do
    member do
      get :following, :followers
    end
  end
  resources :sessions, only: [:new, :create, :destroy]
  resources :microposts, only: [:create, :destroy]
  resources :relationships, only: [:create, :destroy]
  resources :microposts do
  resources :comments

end
  root to: 'static_pages#home'

这是我的 _sent.html.erb

<h2>Sent</h2>
<table>
    <tr>
        <th>Delete?</th>
        <th>Subject</th>
        <th>To</th>
        <th>Sent</th>
    </tr>
    <% if @messages.size == 0 %>
        <tr>
            <td colspan="4">
                No messages
            </td>
        </tr>
    <% else %>
        <% for message in @messages %>
            <tr>
                <td><%= check_box_tag "delete[]", message.id %></td>
                <td><%= link_to h(message.subject), user_message_path(@user, message) %></td>
            <td><%= link_to h(message.recipient_id), user_path(message.recipient) %></td>
              <td><%=h message.created_at.to_s(:long) %></td>
            </tr>
        <% end %>
        <tr>
            <td colspan="4">
                <%= submit_tag "Delete" %>
            </td>
        </tr>
    <% end %>
</table>
<%= link_to "Inbox", user_messages_path(@user)%>

我正在尝试使此链接正常工作 (localhost:3000/users/2/messages?mailbox=sent) 但我收到此错误消息

Routing Error

No route matches {:action=>"show", :controller=>"users"}

您的错误最可能的原因是这一行

user_path(message.recipient)

有一条消息，收件人为零。检查数据库是否有这样的记录。
