Can't update database

[Martin Owens]

The process for getting a fresh branch and working on a bug is extremely hard. The process is multi-joined, required a lot of downloading of external data and code and doesn't fit well into the ground-control workflow even with the scripts I've attempted to allow esier development.

Chief among the problems is the inability to update the database with a new schema without throwing away the entire database and starting from scratch.

What exactly are you suggesting? What does "update the database with a new schema" exactly mean?

[Martin Owens (doctormo)]

Someone adds a new table or a new field and the database fails to incorporate these changes, causing breakage in development workflow.

@Martin, Unless i'm mistaken, every schema change since initial deployment has been accompanied with a south migration method.

What i cannot establish is why a contributer cannot create their own migration, which they would need to do before merge anyway?

[Martin Owens (doctormo)]

Dave: That sounds great, how can these migrations be run? or are they run on syncdb?

[Daniel Holbach (dholbach)]

./manage.py migrate

[Dave Walker (davewalker)]

Just for info, if you look at the last line of syncdb - it does advise of this:

I'm going to mark this as invalid. If there are any problems, please feel free to reopen the bug.
