相关疑难解决方法(0)

我正试图开始南方.我有一个现有的数据库,我添加了South(syncdb,schemamigration --initial).

然后,我更新models.py了添加字段并运行./manage.py schemamigration myapp --auto.它似乎找到了该领域并说我可以应用它./manage.py migrate myapp.但是,这样做会给出错误:

django.db.utils.DatabaseError: table "myapp_tablename" already exists

tablename是第一个列出的表models.py.

我正在运行Django 1.2,South 0.7

我正在尝试应用迁移,但我收到错误:

django.db.utils.OperationalError:(1050,"表'customers_customer'已经存在")

我通过发出以下命令得到这个:

python manage.py migrate

我的客户表已经存在,那么我该如何让迁移知道这一点,而不是出错,并对我的模型进行修改？

我在本地环境中用本地数据库运行它没有问题.当我将数据库指向生产并在migrate上面运行时,我得到了这个错误.

使用django 1.9.所以我试图迁移我的数据库但是我遇到了这个错误.我花了很多时间来解决这个问题并且没有成功.如果有必要,我可以上传更多代码.这是错误:
