Management commands. You can write custom management commands, and you
can programatically invoke other management commands:
from django.core.management.base import NoArgsCommand
from django.core import management
class Command(NoArgsCommand):
help = 'Meta command which calls other commands'
def handle_noargs(self, **options):
management.call_command('loaddata', './apps/addresses/fixtures/cities.json')

Re: Script to call loaddata on multiple fixtures
Thanks, Dennis.
Some of the fixtures are order dependent.
I will have to do some more research on how to use glob.glob() and
spawn.
For now, just adding the list of python loaddata commands to a shell
script seem to work great.
Thanks again for the info!

Re: Script to call loaddata on multiple fixtures
That worked great. I haven't done much shell scripting, but it was easier than I thought. Thanks, Shawn!

Re: Script to call loaddata on multiple fixtures
Why not just put all those manage.py commands in a shell script and run that? -- You received this message because you are subscribed to the Google Groups "Django users" group.
