We have a large number of migrations in our application now, and as a
result it can take 20 mins to create a test DB.
To make this faster I am settings MIGRATION_MODULES in my settings as
follows:
{{{
MIGRATION_MODULES = {}
for app in INSTALLED_APPS:
if app.startswith('django.contrib.'):
app=app.replace('django.contrib.', '')
MIGRATION_MODULES[app] = None
}}}
I've found that this breaks the --keepdb option as it Django wants to run
sync_db internally every time.
The workaround I found is to modify django.db.backends.creation.py (lines
64 to 70) from
{{{
call_command(
'migrate',
verbosity=max(verbosity - 1, 0),
interactive=False,
database=self.connection.alias,
run_syncdb=true,
)
}}}
To
{{{
call_command(
'migrate',
verbosity=max(verbosity - 1, 0),
interactive=False,
database=self.connection.alias,
run_syncdb=not keepdb,
)
}}}
