Re: Migrations During Development

Hi Timothy,

Assuming as an example that 0002_<>.py is the migration that you have already applied to production server, this is the scheme I follow:

• Make sure you have your local db up to date i.e. all the model changes have been applied to database.
• Fake a reversal to the last migration already applied to prod. In this case: manage.py migrate --fake <app_name> 0002
• delete all the migration files after 0002
• run makemigrations: manage.py makemigrations 
• Fake application of the new single migration: manage.py migrate --fake <app>

Now you have a single migration representing all the db changes since the last deploy. Hope this helps.

Regards,

Abhaya

During development I am creating several migrations. It seems unnecessary to keep these since they only exist on my dev machine.  

Any data that I have created can be thrown away too.

Is it safe to delete these migrations  (and the database) before deploying to the next stage for testing by users?
