Question

拥有完成任务的模型和待办事项。在视图中有链接，当点击链接时，它必须将任务从待办事项更改为完成。这是我的路线

get 'tasks/:id', to: 'tasks#change_to_done', as: 'change_to_done'

我的观点

<% unless task.done %>
        <td><%= check_box_tag "cb_tasks[]", task.id %></td>
        <td><%= link_to task.title, task %></td>
        <td><%= link_to 'Edit', edit_task_path(task.id) %></td>
        <td><%= link_to 'Done', change_to_done_path(task.id) %></td>
        <td><%= link_to 'Destroy', task, method: :delete, data: {confirm: 'Are you sure?'} %></td>
      <% end %>

和我的控制器

  def change_to_done
    @task = Task.find(params[:id])
    @task.done = true
    @task.save
  end

单击重定向到显示路径的链接

Started GET "/tasks/32" for 127.0.0.1 at 2017-12-26 11:59:06 +0200
Processing by TasksController#show as HTML
  Parameters: {"id"=>"32"}

  Rendered tasks/show.html.erb within layouts/application (0.7ms)
Completed 200 OK in 57ms (Views: 55.0ms | ActiveRecord: 0.1ms)

怎么了？我只需要将字段状态从false更改为true。

Answer 1

Rails路由按照指定的顺序进行匹配，因此如果您的resources :tasks高于get 'task/:id'，则资源行的show action路线将在获取之前进行匹配线。

尝试更改端点，例如：

get 'change_to_done/:id', to: 'tasks#change_to_done', as: 'change_to_done'

Answer 2

您的路线文件中可能包含resources :tasks。 Rails解决了这个问题，忽略了get 'tasks/:id', to: 'tasks#change_to_done', as: 'change_to_done'这条路线。您应该指定确切的操作get 'tasks/:id/change_to_done', to: 'tasks#change_to_done', as: 'change_to_done'

为什么错误重定向？
