Django：在模板中选择选项 [英] Django: Select option in template

问题描述

在我的Django模板中，我在下拉菜单中使用对象列表。我正在根据选择进行处理。

In my Django template, I am using the list of objects in a drop down menu. I am processing it based on the selection.

HTML模板：

<select id="org" name="org_list" onChange="redirectUrl()">
  <option  value="" selected="selected">---SELECT---</option>
  {% for org in organisation %}
   <option value="{{org.id}}">{{org.name|capfirst}}</option>
  {% endfor %}
</select>

问题是当我从下拉菜单中选择值时，我收到了内容属于选择。由于属性 selected =selected，它仅修复--- SELECT ---元素，除非我将 selected =selected

The problem is that when I am selecting the value from the drop down menu, I am getting the contents which belong to the selection. Since the attribute selected="selected" which only fixes to the "---SELECT---" element, unless I put the selected="selected" in

<option value="{{org.id}}" selected="selected">{{org.name|capfirst}}</option>

在这些组织中，最后一个迭代元素只能用drop下。但是我想要选择的元素显示在下拉菜单中。

In these organisation, the last iterated element is only being fixed with drop down. But I want the selected element to be displayed in the drop down menu.

我如何解决这个问题？

推荐答案

您将要将当前选定的组织传递到视图中，也许是 current_org ，以便您在迭代时您可以与当前的组织进行比较，以确定是否选择它，如：

You'll want to pass the currently selected org into the view, maybe as current_org so that when you're iterating through the orgs you can compare with the current one to determine whether or not to select it, like:

{% for org in organisation %}
   <option value="{{org.id}}"
       {% if org == current_org %}selected="selected"{% endif %}>
       {{org.name|capfirst}}
   </option>
{% endfor %}
