Programmatically using Django's loaddata

Question

I'd like to call the equivalent of manage.py loaddata from a Django view. I'd like to be able to specify where to load the data from and which application to load it into.

Any ideas?

Each django-admin.py (manage.py) command, as seen in the documentation, you can call from your code with:

from django.core.management import call_command

call_command('loaddata', 'myapp')

Where first param is the command name, all other position params are the same as command line position params and all keyword params are options.

you can also add option "verbosity=0" for supression console output: call_command('loaddata', 'fixture_name.json', verbosity=0) – Refurbish

Docs here: docs.djangoproject.com/en/1.8/ref/django-admin/… – Unsought

Please notice that it is not suitable to use loaddata command directly in a data migration, because it internally loads the most up-to-date model definitions and uses them to deserialize historical data in a fixture. That's incorrect behavior. Solution here: https://mcmap.net/q/204333/-loading-initial-data-with-django-1-7-and-data-migrations – Intermix

Also notice that you should use the app_label keyword argument to specify where to load the fixture, e.g. call_command('loaddata', 'initial_data.json', app_label='myapp'). Otherwise, it will load fixtures with the same name from all installed apps. – Intermix
