Django，JSONField，非空列表过滤器

Question

我有一个 jsonfield

foo = JSONField(default=list)

我想过滤查询集，以便 foo 有一些数据（不是空列表）

我试过了

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

MyModel.objects.exclude(foo=[]))

Answer 2

您应该能够通过使用Q对象否定相等性来测试不平等性。

from django.db.models import Q

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