How to handle migrations
Changes to the data model need to be handled through migrations. We use aerich to manage the migration files. Both our CLI and our web service are configured in such a way that migrations are run transparently when the package is updated. If you want to test that the update doesn't corrupt your data, we suggest trying the update in a test database.
To create a new migration file, use aerich CLI. It will take care of generating the file. If further code is necessary, add it to the new migration file.
Since we support two database (sqlite and postgres) that have slightly different dialects and since aerich doesn't really support this scenario, it is necessary to generate migrations separately and place the migrations files in the respective folders.
Aerich picks up the migrations according to the scheme of the db in the configuration.
Currently the consistency of the migrations for the different databases is not tested so please pay extra care when committing a change and request special review.
Aerich configuration is specified in the pyproject.toml file. Since it doesn't support multiple databases, we have two configuration files that allow to run aerich on different databases if you enter their respective migration folders. You can find them in mobilizon_reshare/migrations.
