Where do I set the domain for my Django Sites framework site, when I only have one?

If I understand correctly, Sites framework data is stored in the database, so if I want to store this permanently, I guess it’s appropriate in an initial_data fixture.

I fired up the Django shell, and did the following:

>>> from django.contrib.sites.models import Site
>>> one = Site.objects.all()[0]
>>> one.domain = 'myveryspecialdomain.com'
>>> one.name = 'My Special Site Name'
>>> one.save()

I then grabbed just this data at the command line:

python manage.py dumpdata sites

And pasted it into my pre-existing initial_data fixture.

The other answers suggest to manually update the site in the admin, shell, or your DB. That's a bad idea—it should be automatic.

You can create a migration that'll do this automatically when you run your migrations, so you can be assured it's always applied (such as when you deploy to production). This is also recommended in the documentation, but it doesn't list instructions.

First, run ./manage.py makemigrations --empty --name UPDATE_SITE_NAME myapp to create an empty migration. Then add the following code:

from django.db import migrations
from django.conf import settings


def update_site_name(apps, schema_editor):
    SiteModel = apps.get_model('sites', 'Site')
    domain = 'mydomain.com'

    SiteModel.objects.update_or_create(
        pk=settings.SITE_ID,
        defaults={'domain': domain,
                  'name': domain}
    )


class Migration(migrations.Migration):

    dependencies = [
        # Make sure the dependency that was here by default is also included here
        ('sites', '0002_alter_domain_unique'), # Required to reference `sites` in `apps.get_model()`
    ]

    operations = [
        migrations.RunPython(update_site_name),
    ]

Make sure you've set SITE_ID in your settings. Then run ./manage.py migrate to apply the changes :)

You can change it using django admin site.

Just go to 127.0.0.1:8000/admin/sites/
