有两种方法：
要直接删除它：
SomeModel.objects.filter(id=id).delete()
要从实例中删除它：
instance = SomeModel.objects.get(id=id)
instance.delete()
There are a couple of ways:
To delete it directly:
SomeModel.objects.filter(id=id).delete()
To delete it from an instance:
instance = SomeModel.objects.get(id=id)
instance.delete()

MyModel.objects.get(pk=1).delete()
如果具有指定主键的对象不存在，这将引发异常，因为它首先会尝试检索指定的对象。
MyModel.objects.filter(pk=1).delete()
如果具有指定主键的对象不存在，并且不会直接产生查询，则不会引发异常
DELETE FROM my_models where id=1
MyModel.objects.get(pk=1).delete()
this will raise exception if the object with specified primary key doesn’t exist because at first it tries to retrieve the specified object.
MyModel.objects.filter(pk=1).delete()
this wont raise exception if the object with specified primary key doesn’t exist and it directly produces the query
DELETE FROM my_models where id=1

如果要删除一项
wishlist = Wishlist.objects.get(id = 20)
wishlist.delete()
例如，如果要删除收藏夹中的所有项目
Wishlist.objects.all().delete()
If you want to delete one item
wishlist = Wishlist.objects.get(id = 20)
wishlist.delete()
If you want to delete all items in Wishlist for example
Wishlist.objects.all().delete()

如果要删除一个实例，请编写代码
delet= Account.objects.get(id= 5)
delet.delete()
如果要删除所有实例，请编写代码
delet= Account.objects.all()
delete.delete()
if you want to delete one instance then write the code
entry= Account.objects.get(id= 5)
entry.delete()
if you want to delete all instance then write the code
entries= Account.objects.all()
entries.delete()
