![]() Gitignore the migrations, if You have separate DBs for Development, Staging and Production environment. So in short, if you care about your production data, please check your migrations into version control. They are significant changes to your production system, and there are lots of things that can go wrong with them. Third, migrations should be included in code review. It's not always possible to automatically generate them with. Second, migrations often contain custom, handwritten code. You can create a separate backup of the migrations applied to each production database, but this seems unnecessarily cumbersome. If you deploy changes to production and want to migrate the database, you need a description of the current state. Given that some people here suggested that you shouldn't commit your migrations to version control, I'd like to expand on the reasons why you actually should do so.įirst, you need a record of the migrations applied to your production systems. Of course this only works when there is no conflict between the head migrations, in which case you will have to resolve the problem manually. Which will introduce a new migration that depends on all current head migrations. Often this can be done automatically with the command. One way of resolving this situation is to introduce a merge_migration. if to different developers introduced a migration concurrently. ![]() When merging version control branches, you still may encounter a situation where you have multiple migrations based on the same parent migration, e.g. If you follow this process, you shouldn't be getting any merge conflicts in the migration files. You should be making them once on your development machine and then running the same migrations on your colleagues’ machines, your staging machines, and eventually your production machines. The migration files for each app live in a “migrations” directory inside of that app, and are designed to be committed to, and distributed as part of, its codebase. Quoting from the Django migrations documentation: ![]()
