有没有办法在 Django 中同时循环两个列表? [英] is there a way to loop over two lists simultaneously in django?

问题描述

我有两个长度相同的列表对象，我想渲染互补数据，有没有办法同时渲染两个对象，即.

{% for i,j in table, total %}{{ 一世 }}{{ j }}{% 结束为 %}

或类似的东西?

解决方案

如果两个列表的长度相同，您可以在视图中返回 zipped_data = zip(table, total) 作为模板上下文，它产生一个二值元组的列表.

示例:

<预><代码>>>>lst1 = ['a', 'b', 'c']>>>lst2 = [1, 2, 3]>>>zip(lst1, lst2)[('a', 1), ('b', 2), ('c', 3)]

在你的模板中，你可以这样写:

{% for i, j in zipped_data %}{{ i }}, {{ j }}{% 结束为 %}

另外，看看 Django 的关于 for 模板标签的文档 这里.它提到了使用它的所有可能性，包括很好的例子.

I have two list objects of the same length with complementary data i want to render is there a way to render both at the same time ie.

{% for i,j in table, total %} 
 {{ i }} 
 {{ j }}
{% endfor %} 

or something similar?

解决方案

If both lists are of the same length, you can return zipped_data = zip(table, total) as template context in your view, which produces a list of 2-valued tuples.

Example:

>>> lst1 = ['a', 'b', 'c']
>>> lst2 = [1, 2, 3]
>>> zip(lst1, lst2)
[('a', 1), ('b', 2), ('c', 3)]

In your template, you can then write:

{% for i, j in zipped_data %}
    {{ i }}, {{ j }}
{% endfor %}

Also, take a look at Django's documentation about the for template tag here. It mentions all possibilities that you have for using it including nice examples.
