Django while循环 [英] Django while loop

问题描述

我想知道在django中有没有办法做一个循环（我认为这是我以后的）？

I wonder if there's any way to do a while loop in django (I think that's what I'm after)?

我要做的是一个嵌套的ul / li列表。

What I'm trying to do is a nestled ul/li list.

该列表由for循环中的for循环生成。但是由于第二个for循环中的某些元素有更多的子节点，我想要遍历它们，等等，直到所有子节点被迭代出来。到目前为止我发现的唯一办法就是要有另一个循环。但这似乎不是通用的和相当重复的。而且我需要知道孩子们有多少级别。

The list is generated by a for loop in a for loop. But since some elements in the second for loop has more child's I want to iterate or them to and so on until all child nodes are iterated out. Only way I found so far is to have another for loop. But this seems not to generic and quite repetitive. And I need to know how many "levels" of child's there are.

这是现在的样子：

<ul>
    {% for item in items %}
        <li>
            {{ item.name }}
            {% if item.childs %}
                <ul>
                    {% for child in item.childs %}
                        <li>{{ child.name }}</li>
                    {% endfor %}
                 </ul>
            {% endif %}
        </li>
    {% endfor %}
</ul>

还是有更智能的方式将数据发送到模板？
可以使用某种for / while循环吗？

Or is there a smarter way to send the data to the template? Can one do this with some kind of for/while loop?

推荐答案

将列表转成包含标签，然后包含它。

Turn the list into an inclusion tag, then include it in itself.
