Is boolean logic possible in django templates?
提问by willcritchlow
I want to do something like:
我想做类似的事情：
{% if ("view_video" in video_perms) OR purchase_override %}
Is that possible?
那可能吗？
采纳答案by Spacedman
Django docs on boolean operators
Gives you:
给你：
{% if user in users %}
If users is a QuerySet, this will appear if user is an
instance that belongs to the QuerySet.
{% endif %}
and
和
{% if a == b or c == d and e %}
Be aware that andhas a higher order of precedence than or, and that parentheses are not possible. If required use nested blocks.
请注意，and的优先级高于or，并且括号是不可能的。如果需要，使用嵌套块。
