How can I use the current Site as the default in a Django form using the Sites Framework?

Question

I'm using the Sites Framework and want to save the current site as the default site value for one of my models.

Model:

class MyModel(models.Model):
    site = models.ForeignKey(
        Site, 
        on_delete=models.CASCADE, 
        default=Site.objects.get_current())  # THIS IS WHAT I WANT TO DO (DOESN'T WORK)
    ...other fields...

Is there a way to automatically save the current Site object as the site attribute of MyModel anytime I save a MyModel instance? Or would I need to do this manually by overriding either the form's or the model's save method, (or similar override)?

What you mean doesn't work? – Aamir Rind Sep 19 '17 at 20:16 — Aamir Rind, Sep 19 '17 at 20:16

You can set the default site.

models.py

def get_current_site():
    return Site.objects.get_current().id


class MyModel(models.Model):
    site = models.ForeignKey(
        Site,
        on_delete=models.CASCADE,
        default=get_current_site)

This will only work if you have created a site in your database and also set the SITE_ID in settings.py
