在 heroku 上推送我的代码后没有进行迁移...？

Question

好吧，已经 12 个小时了，我仍然无法正确部署我的项目。我只是不知道发生了什么错误。你们可以看到这样的模型不存在的错误。但我试图让我的 heroku run python manage.py makemigrations 迁移，它通过我这个回溯。我的代码在本地运行良好，但在服务器端却发生了这种情况。请帮帮我。

如果需要更多代码，请在评论会话中告诉我。我会用这些信息更新我的问题。

你不应该在 heroku 上运行 makemigrations。迁移应该添加到您的存储库中，然后您的部署计划使用这些迁移文件在数据库上执行迁移。

Heroku 有一个release 阶段，此时应该执行python manage.py migrate。如果迁移失败，将不会部署使用它们的新代码。

如果您不想添加此阶段，因为您不喜欢它 - 没问题。只是不要运行makemigrations。

如果由于某种原因，您无法在本地创建迁移，请注释掉此表单，运行 makemigrations，运行 migrate 并取消注释此代码。

如果 heroku 仍然抱怨，请在 heroku 上重复这些步骤 ^。

但想法是你只在 heroku 上运行

• python manage.py migrate（如果可能，release 阶段）
• gunicorn something something (web dyno)
