Django，JSONField，过滤非空列表

Question

我有一个jsonfield

foo = JSONField(default=list)

我想过滤查询集，以便foo包含一些数据（不是空列表）

我已经尝试过

MyModel.objects.filter(foo__ne=[])  # doesn't seem to work
MyModel.objects.filter(foo__gt=[])  # seems to work but can't be sure if it's the right approach

Answer 1

您应该能够通过使用Q对象取反相等来测试不平等。

from django.db.models import Q

MyModel.objects.filter(~Q(foo=[]))
