Re: Migrations with multiple databases

Hi Andrea,

If you have models that are entirely unrelated in different databases
you could use different values for INSTALLED_APPS to limit the apps
Django sees or by settings the values in the MIGRATION_MODULES dict to
None to tell Django that those apps don't have migrations.

Cheers,

/Markus
