该类Customer有一个类的外键User。我想返回此信息，但我不想在用户名、名字等之前显示 user__。data = {"customers": list(p.values("id", "user__username", "user__first_name", "user__last_name", "user__email", "phone", "address", "balance"))}我怎样才能得到这样的东西：{"customers": [ { "id": 12, "username": "leon2", "first_name": "lee", "last_name": "michalson", "email": "
[email protected]", "phone": "042-22334455", "address": "Tehran, No.1", "balance": 20000 }]}

使用注释：
from django.db.models import F
for field in ('username', 'first_name', 'last_name', 'email'):
p = p.annotate(**{field: F('user__' + field)})
data = {"customers": list(p.values("id", "username", "first_name",
"last_name", "email", "phone",
"address", "balance"))}
