Hi,

I have recently returned to a Django project after a few years and I'm a little rusty on ManyToMany fields.

Here's my very simple models:

class Studio(models.Model):
    name = models.CharField(max_length=255, unique=True)

class StudioGroup(models.Model):
    description = models.CharField(max_length=255, unique=True)
    studio = models.ManyToManyField(Studio)

So a bunch of Studio(), which can be in multiple StudioGroups()

Given a single instance of a Studio(), I would like a single list of all other studios in all other groups.

so if Group1 is A,B,C and Group2 is A,D,E

I would like to return B,C,D,E for A.

My current solution is entirely in Python (which works), but I'd like a more Django-esque solultion of possible!

Thank you,
