我正在尝试将南添加到我在 Heroku 上的项目中。我按照以下步骤操作。
heroku run easy_install South
添加'south'在INSTALLED_APPS_settings.py
然后
heroku run ./manage.py syncdb
heroku run ./manage.py convert_to_south sheets
追溯
Running `./manage.py convert_to_south sheets` attached to terminal... up, run.2005
Creating migrations directory at '/app/sheets/migrations'...
Creating __init__.py in '/app/sheets/migrations'...
+ Added model sheets.Sheets
+ Added model sheets.UserSheets
+ Added M2M table for users on sheets.UserSheets
+ Added model sheets.SheetScribble
+ Added model sheets.SheetScribbleComment
+ Added model sheets.Tasks
+ Added model sheets.TaskComment
Created 0001_initial.py. You can now apply this migration with: ./manage.py migrate sheets
- Soft matched migration 0001 to 0001_initial.
Running migrations for sheets:
- Nothing to migrate.
- Loading initial data for sheets.
Installed 0 object(s) from 0 fixture(s)
App 'sheets' converted. Note that South assumed the application's models matched the database
(i.e. you haven't changed it since last syncdb); if you have, you should delete the sheets/migrations
directory, revert models.py so it matches the database, and try again.
然后当我尝试将我的第二个应用程序转换为南时，
heroku run ./manage.py convert_to_south scribbler
我收到这个错误
Running `./manage.py convert_to_south scribbler` attached to terminal... up, run.6046
Creating migrations directory at '/app/scribbler/migrations'...
Creating __init__.py in '/app/scribbler/migrations'...
+ Added model scribbler.ScribbleMedia
+ Added model scribbler.Scribble
+ Added model scribbler.Tag
+ Added M2M table for scribbles on scribbler.Tag
+ Added model scribbler.SharedScribble
+ Added M2M table for users_favored on scribbler.SharedScribble
+ Added model scribbler.ScribbleComment
+ Added model scribbler.Connections
+ Added unique constraint for ['following', 'followers'] on scribbler.Connections
+ Added model scribbler.UserProfile
+ Added model scribbler.Invitation
+ Added model scribbler.Notifications
Created 0001_initial.py. You can now apply this migration with: ./manage.py migrate scribbler

我不确定问题是什么。
