当然可以,具体可以参考 官方文档
这里举几个例子:
{% if athlete_list and coach_list %}
Both athletes and coaches are available.
{% endif %}
{% if not athlete_list %}
There are no athletes.
{% endif %}
{% if athlete_list or coach_list %}
There are some athletes or some coaches.
{% endif %}
{% if not athlete_list or coach_list %}
There are no athletes or there are some coaches (OK, so
writing English translations of boolean logic sounds
stupid; it's not our fault).
{% endif %}
{% if athlete_list and not coach_list %}
There are some athletes and absolutely no coaches.
{% endif %}
and和or也可以一起使用,但是, and比or具有更高的优先级,比如:
{% if athlete_list and coach_list or cheerleader_list %}
将被解析为:
if (athlete_list and coach_list) or cheerleader_list
