我试图使用命令更新我的数据库
python manage.py makemigrations
之后，删除Django项目中所有迁移文件，因为当我尝试对数据库进行更改时，这些更改不适用
这是我的模型
class ciudades(models.Model):
ciudad_nombre = models.CharField(max_length=50)
estado = models.CharField(max_length=50)
def __str__(self):
return self.name
class Meta:
db_table = 'ciudades'
verbose_name ='Ciudad'
verbose_name_plural = 'Ciudades'
这是我得到的错误
