如何遍历jinja中的列表列表 [英] how to iterate over a list of list in jinja

问题描述

我有一个列表列表，如:

I have a list of list like :

    [[elem0, elem1, elem2], [elem3, elem4, elem5], [elem6, elem7, elem8], ...]

我编写了以下模板文件:

I wrote the follow template file :

    {% for result in results %}
        <tr>
            <td>result[0]</td>
            <td>result[1]</td>
            <td>result[2]</td>
        </tr>
    {% endfor %}

但是它没有用，我能想到的是嵌套使用.还有另一种方法可以访问Jinja列表中的元素吗?

But it didn't work, What i can think is use nested for. Is there another method to access the element in the list in jinja?

推荐答案

您仍然需要在括号内输出循环变量.

You still need to output the loop variables inside braces.

{% for result in results %}
            <tr>
                <td>{{ result[0] }}</td>
                <td>{{ result[1] }}</td>
                <td>{{ result[2] }}</td>
            </tr>
{% endfor %}

另外，考虑嵌套的for循环:

Also, consider a nested for loop:

{% for result in results %}
  {% for elem in result %}
    <td>{{elem}}</td>
  {% endfor %}
{% endfor %}
