我想计算状态为 2 的保单数量，并按日期和 health_facilities 进行筛选。

尝试做：
policies = (Policy.objects.filter(status=2)
.filter(start_date__gte=date_from
.filter(expiry_date__lte=date_to).count()
这将返回属于该过滤器类别的
countPolicyquerysetcountquerysetPolicy你的问题不清楚。
如果您想获取特定医疗机构的所有保险单的数量（按日期和状态筛选），您可以这样做：
from django.db.models import Q
count = InsureePolicy.objects.filter(
Q(insuree__health_facility=health_facility) &
Q(policy__status=2) &
Q(start_date__gte=date_from) &
Q(expiry_date__lte=date_to)
).count()
这将返回特定医疗机构拥有多少份保险单，其中父保单的状态为 2 并按日期过滤。
编辑：
但是，如果您想查看特定医疗机构有多少种不同的类型政策，您可以执行以下操作：
count = Policy.objects.filter(
Q(insuree_policies__insuree__health_facility=health_facility)
Q(status=2) &
Q(start_date__gte=date_from) &
Q(expiry_date__lte=date_to)
