Question

我的数据库中有一个简单的插入问题（如本post中所述）。我问了一个新问题，因为问题有点不同。

我的模型和sql表是相同的，我尝试插入一行指定了一个字段，它返回一个错误，说它不知道另一个字段..

我的sql表如下所示：

FeuilleTemps | CREATE TABLE `FeuilleTemps` (
  `f_id` int(11) NOT NULL AUTO_INCREMENT,
  `f_id_user` int(11) DEFAULT NULL,
  `f_date` date DEFAULT NULL,
  `f_id_proj` int(11) DEFAULT NULL,
  `f_comment` longtext,
  `f_id_task` int(11) DEFAULT NULL,
  `f_unite` int(11) DEFAULT NULL,
  `f_absent` int(11) DEFAULT NULL,
  PRIMARY KEY (`f_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |

然后我打电话给inspectdb --database ='myDb'＆gt; models.py

在models.py中我有这个：

class Feuilletemps(models.Model):
    f_id = models.IntegerField(primary_key=True)
    f_id_user = models.IntegerField(null=True, blank=True)
    f_date = models.DateField(null=True, blank=True)
    f_id_proj = models.IntegerField(null=True, blank=True)
    f_comment = models.TextField(blank=True)
    f_id_task = models.IntegerField(null=True, blank=True)
    f_unite = models.IntegerField(null=True, blank=True)
    f_absent = models.IntegerField(null=True, blank=True)
    class Meta:
        db_table = u'FeuilleTemps'

然后我尝试进行以下插入查询：

f = Feuilletemps(f_id_user=1085)
f.save()

它给了我这个错误：

OperationalError: (1054, "Unknown column 'f_id_proj' in 'field list'")

Answer 1

好的，我终于明白了。我需要打电话

f.save(using='myDb')

语法的这种变化有点令人困惑，因为我通常使用类似

的东西

Feuilletemps.objects.using('myDb').get(f_id=1)

Django - OperationalError：（1054，“字段列表'中的未知列'xx'”）
