在Heroku上运行迁移时,我总是收到ValueError。 我的django应用程序在本地没有问题。从我所能看到的情况来看,我认为问题出在这个模型上,但我找不到它会是什么。特别是因为运行makemigrations并迁移本地工作就好了。Heroku Django ValueError:无效文字为int()以10为底:' - '

的错误,我得到:(注:仅在Heroku上运行时:heroku run python manage.py migrate

我改变0012_auto_20170808_1312.py文件,有行时整数提交了默认为 “ - ”。我删了它。但我仍然不知道为什么在当地这不是问题?

您是否在本地使用与heroku相同的数据库? –

是的我使用相同的数据库 –

我最好的猜测是,当你在本地运行时,默认值是别的东西,无论是在makemigrations期间用户输入还是文件不同。 ValueError有效,如果DBMS相同,则应在同一迁移文件上本地提出。 –
