Django(25)删除记录

删除有两种方法
1，模型类对象.delete

student = Student.objects.get(id=13)
student.delete()

2，模型类.objects.filter().delete()

Student.objects.filter(id=14).delete() 

# 1. 先查询到数据模型对象。通过模型对象进行删除
student = Student.objects.filter(pk=13).first()
student.delete()

# 2. 直接删除
ret = Student.objects.filter(pk=100).delete()
print(ret)
# 务必写上条件，否则变成了清空表了。ret = Student.objects.filter().delete()
