[django-migration-linter](https://github.com/3YOURMIND/django-migration-linter)

([PyPI package information](https://pypi.org/project/django-migration-linter/))

checks for backwards-incompatible changes in [Django ORM](/django-orm.html)

schema migrations and warns you about them. The purpose of the project is

to save time in older and larger projects by detecting field migrations

that will be a problem so you do not run into issues later, and make it

easier to enable continuous [deployment](/deployment.html) configurations

with database changes. There is a

[blog post on keeping Django database migrations backward compatible](https://medium.com/3yourmind/keeping-django-database-migrations-backward-compatible-727820260dbb)

that goes into further detail on the tool.
