使用Django和Heroku的南方麻烦

Question

我有一个现有的Django项目,我刚刚添加到南方.

• 我在本地运行syncdb.
• 我在manage.py schemamigration app_name当地跑
• 我在manage.py migrate app_name --fake当地跑
• 我承诺并推送到heroku主人
• 我在heroku上运行了syncdb
• 我跑manage.py schemamigration app_name了heroku
• 我跑manage.py migrate app_name了heroku

然后我收到这个:

$ heroku run python notecard/manage.py migrate notecards
Running python notecard/manage.py migrate notecards attached to terminal... up, run.1
Running migrations for notecards:
 - Migrating forwards to 0005_initial.

我有3个型号.部分,学期和记录卡.我在Notecards模型中添加了一个字段,我无法在Heroku上添加它.

谢谢.

您必须伪造创建表的迁移,然后照常运行其他迁移.

manage.py migrate app_name 000X --fake
manage.py migrate app_name 

000X是您创建表的迁移数.
