django1.1版本中根据外键约束的字段获取相关字段模型类的方法是field_object.rel.model
-- models.py
class UserInfo(models.Model):
'''
用户表
'''
name = models.CharField(verbose_name="姓名", max_length=12)
gender_choices = (
(1, "男"),
(0, "女")
)
gender = models.IntegerField(verbose_name="性别", choices=gender_choices, default=1)
age = models.CharField(verbose_name="年龄", max_length=3)
email = models.EmailField(verbose_name="邮箱")
depart = models.ForeignKey(to=Depart, verbose_name="所属部门", on_delete=models.CASCADE)
class Meta:
db_table = "db_user_info"
def __str__(self):
return self.name
class Depart(models.Model):
'''
部门表
'''
title = models.CharField(verbose_name="部门名称", max_length=12)
class Meta:
db_table = "db_depart"
def __str__(self):
return self.title
-- views.py
from app01.models import UserInfo
from django.shortcuts import Httpresponse
def test(request):
# 根据字段名拿到字段对象
depart_object = UserInfoUserInfo._meta.get_field("depart")
# 根据字段对象获取相关模型类
depart_model = depart_object.rel.model
queryset = depart_model .objects.all()
print(queryset)
return Httpresponse("ok")
django3.2版本中根据外键约束的字段获取相关字段模型类的方法是field.related_model
-- models.py文件同上
-- views.py
from app01.models import UserInfo
from django.shortcuts import Httpresponse
def test(request):
# 根据字段名拿到字段对象
depart_object = UserInfoUserInfo._meta.get_field("depart")
# 根据字段对象获取相关模型类
depart_model = depart_object.related_model
queryset = depart_model.objects.all()
print(queryset)
return Httpresponse("ok")
