Instead of rushing to a decision if and of how we continue to support "apps w/o migrations" I would argue that, since Django's test suite does infact create tables for apps w/o migrations, we could add a commandline flag (e.g. --run-syncdb or whatever) to the migrate command and warn the user if there are apps w/o migrations an the user doesn't supplied: https://github.com/django/django/blob/master/django/core/management/commands/migrate.py#L136

Do we know exactly what "support for apps without migrations" would consist of at this point? I have that half-done code for replicating syncdb with the autodetector stuck onto the migration executor, but it's not especially speedy and would need some work to make it a sensible speed before it goes forward. Alternately, we could modify the autodetector to have a "create only" mode that's more efficient or just write a new generator that is quick because it knows it's only making nonmigrated apps' migrations.

Is anyone sufficiently interested in continuing support for apps without migrations to commit to completing it by the alpha? If not, do you consider it a release blocker that I should spend time on?

This would even allow apps without migrations to depend on those with migrations. We have to consider though, that there are tens of apps and hundreds of models in our own test suite, and generating all migrations during start seems to be quite an expensive task. And I'm not even talking about the migration optimizer which probably needs to get a lot smarter if we take this road. syncdb, which leaves a developer with a database scheme that cannot be altered automatically, is something we should get rid of as soon as possible, especially since Django has a out-of-the-box migration system. /Markus On Sun, Jan 18, 2015 at 01:50:14PM -0800, Andrew Godwin wrote: >My main argument for removing them entirely was the dependency issues >between apps with and without migrations.
