在heroku上推送我的代码后没有发生迁移…?

Question

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事。你们可以通过错误看出这样的模型并不存在。但我正试图使迁移我的heroku运行python manage.py makemigrations&strong>它通过我追溯。我的代码在本地工作得很好，但在服务器端这正在发生。请帮帮我。

如果需要更多的代码，然后在注释会话中告诉我。我将用这些信息更新我的问题。

Answer 1

不应该在heroku上运行makemigrations。迁移应该添加到您的repo中，然后您的部署计划使用这些迁移文件在DB上执行迁移。

Heroku在执行python manage.py migrate时出现了release相。如果迁移失败，使用它们的新代码将不会被部署。

如果你不想添加这个阶段，因为你不喜欢它-没有问题。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。

如果heroku仍然抱怨，对heroku也重复这些步骤。

但是这个想法是在heroku上你只运行

• python manage.py migrate(release相如果可能)
• gunicorn something something(webdyno)
