Jinja中的字符串串联 [英] String concatenation in Jinja

问题描述

我只想遍历现有列表，并用逗号分隔字符串.
像这样:my_string = 'stuff, stuff, stuff, stuff'

I just want to loop through an existing list and make a comma delimited string out of it.
Something like this: my_string = 'stuff, stuff, stuff, stuff'

我已经了解了loop.last，我只需要知道如何在我的代码下将第三行写到WORK.

I already know about loop.last, I just need to know how to make the third line in my code below WORK.

{% set my_string = '' %}
{% for stuff in stuffs %}
{% set my_string = my_string + stuff + ', '%}
{% endfor%}

推荐答案

如果stuffs是字符串列表，则可以使用:

If stuffs is a list of strings, just this would work:

{{ stuffs|join(", ") }}
