Django ManyToMany Query交集

Question

我有以下模型结构：

class Person(model.Models):
    groups = models.ManyToManyField(Group)

class Group(model.Models):
    pass

class Event(model.Models):
    groups = models.ManyToManyField(Group)

我现在要做的是获取包含特定Event所在的Group的所有Person。我该怎么做？

Answer 1

这应该有效：

Event.objects.filter(groups__person=person)
