Django模板，如何使一个下拉框与预先定义的值被选中？ [英] Django template, how to make a dropdown box with the predefined value selected?

问题描述

我正在尝试创建一个下拉列表框，其中所选值等于从模板值传递的值，但没有成功。任何人都可以看看，告诉我我做错了什么。

I am trying to create a drop down list box with the selected value equal to a value passed from the template values, but with no success. Can anyone take a look and show me what I am doing wrong.

     <select name="movie">
       {% for movie in movies %}
    {% ifequal movie.id selected_movie.id %}
     <option value="{{movie.key}}" selected="true">Movie {{movie.id}}: {{movie.name}}</option>
     {% endifequal %}
     {% ifnotequal movie.id selected_movie.id %}
     <option value="{{movie.key}}">Movie {{movie.id}}: {{movie.name}}</option>
     {% endifnotequal %}
       {% endfor %}
     </select>

在此示例中，将从模板值传递电影和selected_movie。
请咨询！

In this example, movies and selected_movie are passed from the template values. Please advice!

推荐答案

您的代码适用于django 1.0.2和firefox 3.5。

Your code works for me with django 1.0.2 and firefox 3.5.

您可以使用{％else％}而不是{％ifnotequal％}并设置selected =selected。希望它有帮助。

You can use {% else %} instead of {% ifnotequal %} and set selected="selected". Hope it helps.

<select name="movie">
    {% for movie in movies %}
        {% ifequal movie.id selected_movie.id %}
            <option value="{{movie.key}}" selected="selected">Movie {{movie.id}}: {{movie.name}}</option>
        {% else %}
            <option value="{{movie.key}}">Movie {{movie.id}}: {{movie.name}}</option>
        {% endifequal %}
    {% endfor %}
</select>
