理想情况下，您要做的是创建一个模板获取的列表:

Ideally what you would do is create a list that the template gets as such:

l = [s.name for s in sections]

在模板中，使用:

{% if 'Social' in l %}

您正试图在模板中加入比预期更多的逻辑.模板应该尽量少用逻辑，而逻辑应该在填充模板的代码中.

You're trying to put more logic into a template than they are meant to have. Templates should use as little logic as possible, while the logic should be in the code that fills the template.
