如何打破“for loop”在Django模板

问题描述：

我有这个代码

    {% for account in object_list %}
        <tr>
        {% for field, value in book.get_fields %}
              <th>{{ field.verbose_name }}</th> 
        {% endfor %}
        </tr>
    {{ break }}
    {% endfor %}

我想在第一次迭代后打破for循环。破解不起作用

I want to break the for loop after first iteration. break is not working

答

Django模板系统中没有 break 。 Django模板系统未使用 python 编程，但拥有自己的语言。

There is no break in Django template system. Django template system is not programmed with python but with its own language.

根据您需要做什么，您可能会发现这个问题有用。否则，只需在 RequestContext 上的特殊字段上唯一的帐户 打印 HTML 。

Depending on what you need to do, you might find this question useful. Otherwise, just put the one and only account you are trying to print on HTML on a special field on your RequestContext.
