mysql - django 向 sql 插入一行

Question

我是 django 的新手。我想在 MySQL 数据库中插入一个新行，但是当我尝试执行以下操作时，它出错了。

from django.db import models
...
class Msg(models.Model):
    MsgId = BigIntegerField(length = 20)
    ToUserName = CharField(max_length = 45)
    FromUserName = CharField(max_length = 45)
    Content = TextField(max_length = 1024, blank = True)
...
db_entry = Msg(MsgId=received_MsgId, ToUserName=received_ToUserName,
               FromUserName=received_FromUserName, MsgType=received_MsgType,
               Content=received_Content)
db_entry.save()

以下是我的数据库中存在的表 all_massages，我如何向它添加新行，以及我需要做哪些额外的事情。

+--------------+---------------------+------+-----+---------+-------+
| Field        | Type                | Null | Key | Default | Extra |
+--------------+---------------------+------+-----+---------+-------+
| MsgId        | bigint(20) unsigned | NO   | PRI | NULL    |       |
| ToUserName   | varchar(45)         | NO   |     | NULL    |       |
| FromUserName | varchar(45)         | NO   |     | NULL    |       |
| Content      | text                | YES  |     | NULL    |       |

如果您更改了模式并执行了 syncdb ...它不会工作...所以删除现有表并执行 syncdb!!
