Django South - 表已经存在 [英] Django South - table already exists

问题描述

我正在努力开始南方。我有一个现有的数据库，我添加了南（ syncdb ， schemamigration --initial ）。

然后，我更新了 models.py 添加一个字段并运行 ./ manage.py schemamigration myapp - 自动。似乎找到了这个字段，并说我可以用 ./ manage.py migrate myapp 应用这个字段。但是，这样做会出错：

  django.db.utils.DatabaseError：表myapp_tablename已经存在
  

tablename 是 models.py 。

我正在运行Django 1.2，South 0.7

解决方案

由于您已经在数据库中创建了表，您只需要运行初始迁移作为假的

  ./ manage.py migrate myapp --fake 
  

确保模式模型与数据库中表格的模式相同。

I am trying to get started with South. I had an existing database and I added South (syncdb, schemamigration --initial).

Then, I updated models.py to add a field and ran ./manage.py schemamigration myapp --auto. It seemed to find the field and said I could apply this with ./manage.py migrate myapp. But, doing that gave the error:

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

tablename is the first table listed in models.py.

I am running Django 1.2, South 0.7

解决方案

since you already have the tables created in the database, you just need to run the initial migration as fake

./manage.py migrate myapp --fake

make sure that the schema of models is same as schema of tables in database.
