Ah, thanks for the heads up!

Unfortunately, syncdb will install the latest SQL for all installed
applications (as far as I am aware). Is there a way just to install the
schema for a specific application? I guess I could call sqlall and run
each supplied statement, but that's pretty much just reimplementing
install ;-)

The reason I need to do this is because keeping track of the revision a
model is at and working out which migrations need to be run gets quite
complex. For this initial version of the migrator I am doing all SQL
through the migrations. Of course, the django management can be used to
generate those initial migrations...

I have some documentation up at

http://www.asmwc.com/dbmigration/

(this is changing literally minute by minute as I produce it!)

Perhaps what I need to do is keep a revision number in each model's Meta
class. Then when I roll out a model to a server the migrator can check
to see if it has been installed before. If not, it can use django to
generate the sql and install it. If it has been installed before it can
see what revision was installed previously and run the migrations that
are flagged with the intermediate revision numbers...
