django heroku makemigrations忽略了模型的更改 [英] django heroku makemigrations ignoring changes in models

问题描述

我从models.py中删除了两个模型，当我运行makemigrations并在本地迁移时，一切都很好.在Heroku上运行makemigrations时，收到以下消息，其中Building和BuildingInstance是我删除的模型:

I deleted two models from models.py, and when I run makemigrations and migrate locally, everything is fine. When I run makemigrations on Heroku, I get the following message, where Building and BuildingInstance are the models I deleted:

Migrations for 'hello':
0002_building_buildinginstance.py:
- Create model Building
- Create model BuildingInstance

运行迁移时，我得到:

Running migrations:
No migrations to apply.
Your models have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

我遵循了这里.我该如何解决这个问题?

I followed the steps here and also tried squashing the migrations locally and on Heroku as suggested here. How can I fix this problem?

推荐答案

正如我在这里多次写的那样，您一定不要在Heroku上运行makemigrations.在本地运行它，提交结果，然后在Heroku上运行迁移.

As I have written many times here, you must not run makemigrations on Heroku. Run it locally, commit the result, and then​ run migrate on Heroku.
