我的模型定义如下，当我运行 python manage.py sql 应用程序时，它什么都没有。我的应用程序名称是应用程序。当我将模型的内容更改为教程 https://docs.djangoproject.com/en/1.5/intro/tutorial01/ 时，它出现了正确的 sql 语句，所以它必须在下面的模型中出现错误，任何人都可以指出它出去？

class Applicationinfo(models.Model):
    applicationinfo_id = models.BigIntegerField(primary_key=True, db_column='ApplicationInfo_id') # Field name made lowercase.
    mainproduct = models.CharField(max_length=300, db_column='MainProduct') # Field name made lowercase.

    mainproductownermail = models.CharField(max_length=96, db_column='MainProductOwnerMail', blank=True) # Field name made lowercase.
    applicationreason = models.CharField(max_length=500, db_column='ApplicationReason', blank=True)
    filetype = models.BooleanField(db_column='FileType')
    applicationstatus = models.IntegerField(db_column='ApplicationStatus')

    class Meta:
        db_table = 'applicationinfo'
        app_label = 'backupcenter1'

app_label设置为'backupcenter1'，删除它。

app_label = 'backupcenter1'这意味着，据 Django 所知，这个模型不属于你的application应用程序，而是属于backupcenter1应用程序。因此，为什么它没有出现在application应用程序的 SQL 输出中。

另外，请注意这application是一个糟糕的应用程序名称，您可能想要更改它。
