I recently came across the need to let admins create/edit specific objects from Django admin with an inline formset (nested forms).

In Rails, this can be accomplished by simply doing this.

accepts_nested_attributes_for :model

Things are a little bit different in Django. As opposed to Rails, Django provides an admin interface by default but getting the same to work in a nested way isn’t very obvious.

class Provider(models.Model):
	name  = models.CharField(max_length=100)
 	slug  = models.CharField(max_length=100, null=True, blank=True)
 	url = models.CharField(max_length=255, null=True, blank=True)
 	image_url = models.CharField(max_length=255, null=True, blank=True)

class ProviderConfig(models.Model):
	provider = models.ForeignKey(Provider)
	...# regular django model fields

The problem statement is simple, I need to show and create ProviderConfig together with the Provider. I boiled a fresh pot of brew and started digging. A couple of hours later I was finally able to wrap my head around this.
