管理器Manager
管理器是Django的模型进行数据库的查询操作的接口
from django.db import models
# 添加一个UserInfo管理类
# 这是继承models.Manager类
class UserInfoManage(models.Manager):
"""管理类"""
def get_queryset(self):
return super(UserInfoManage, self).get_queryset().filter(is_delete=False)
def create(self, user_name, password, email):
m = UserInfo()
m.user_name = user_name
m.password = password
m.email = email
m.save()
return m
def update(self):
pass
class UserInfo(models.Model):
"""这是一个用户信息的类"""
user_name = models.CharField(max_length=20)
password = models.CharField(max_length=40)
email = models.CharField(max_length=20)
address = models.CharField(max_length=30, default='')
recipient = models.CharField(max_length=20, default='')
post_code = models.CharField(max_length=6, default='')
phone = models.CharField(max_length=11, default='')
is_delete = models.BooleanField(default=False)
# 添加一个属性来调用UserInfoManage()
manage = UserInfoManage()
在视图中调用时UserInfo.manage.create(user_name, password, email)就可以创建一个新的数据
