仅显示所需的参数

问题描述

我按照本教程(没有脚手架)创建了一个应用.

I created an app following this tutorial (without scaffolding).

创建一个项目后，我可以单击它，它显示了一大堆参数.例如此处: http://s15.postimage.org/j6at9koiz/parameters.png .

After I create an item I can click on it and it shows me a big list of parameters. Like here: http://s15.postimage.org/j6at9koiz/parameters.png .

执行该操作的代码是

<% if (todos && todos.length) { %>
  <% for (var i in todos) { %>
  <div class="row todo-item">
    <div class="span8">
        <h3><%- linkTo(todos[i].title, todoPath(todos[i].id)) %></h3>
    </div>
    <div class="span4"><h3><i class="icon-list-alt"></i><%= todos[i].status; %></h3></div>
  </div>
  <% } %>
<% } %>

更具体地说，下面一行是显示带有标题的链接的链接，这些链接将我带到每个项目的参数列表:

To be more specific, the following line is the one which displays the links with the titles which take me to the list of the parameters for each item:

<%- linkTo(todos[i].title, todoPath(todos[i].id)) %>

我可以做些什么以仅显示某些参数，而不显示现在显示的整个列表吗?

Can I do something to display only some of the parameters and not the entire list which is displayed now?

谢谢！

推荐答案

您需要添加待办事项资源的视图文件.如果您使用的是脚手架，则geddy会默认创建它们.但是否则，您必须在app/views/todos中添加待办事项的视图文件.

You need to add view files for todo resource. If you're scaffolding, then geddy creates them by default. But otherwise, you have to add view files for todo in app/views/todos.

查看文件

• _form.html.ejs
  • 修改/新表格
  • _form.html.ejs
    • edit/new form
    • 新资源视图
    • /todos/add
    • 修改视图
    • /todos/:id/edit
    • 索引视图
    • /todos
    • 显示个人资源
    • /todos/:id

    您可以手动编辑它们.要更改单个待办事项在/todos/:id路线上的显示方式，请编辑show.html.ejs

    You can edit them manually. For changing how a individual todo item should appear on /todos/:id route, edit show.html.ejs

    <div class="hero-unit">
      <%- linkTo('Edit this todo', editTodoPath(params.id), {class: 'btn pull-right'}); %>
      <h3>Params</h3>
      <ul>
        <li>todo.title</li>
        <li>todo.property1</li>
        <li>todo.property2</li>
      </ul>
    </div>
