Rails 3 - html.erb中的表

Question

我想在视图中查看来自不同数据库表的数据,如下图所示:

我熟悉的HTML标签<table>,<td>和<tr>,但我在与一列多个查询的麻烦.

<table>
  <tr>
    <th>Skills &nbsp; &nbsp; &nbsp;</th>
    <th>Expected-qualifications</th>
    <th>Current-qualifications</th>
  </tr>

   <% @employee.position.skills.each do |skill| %><% @employee.position.expected_qualifications.each do |expected_qualification| %><% @employee.current_qualifications.each do |current_qualification| %>
  <tr>
    <td><%= skill.kategorien %></td>
    <td><%= expected_qualification.sollqualifikation %></td>
    <td><%= current_qualification.istqualifikation %></td>
  </tr>
  <% end %><% end %><% end %>

</table>

此代码如下所示:

如您所见,技能,预期资格和当前资格重复.

我的问题:如何在表格中排序代码,以便它看起来像我想要的那样？

Answer 1

试试zip:

<% @employee.position.skills.zip(@employee.position.expected_qualifications,@employee.current_qualifications).each |skill expected_qualification current_qualification| %>
<tr>
  <td><%= skill.kategorien %></td>
  <td><%= expected_qualification.sollqualifikation %></td>
  <td><%= current_qualification.istqualifikation %></td>
</tr>
<% end %>
