[Answer]-How can I change an OneToOne field in django Custom User?

✅

It’s because the channel field on your CustomUser model has primary_key=True.

This means when you do:

In [96]: u.channel = c2

In [97]: u.save()

…you have changed the primary key of u, therefore when you save it is creating a new user, but with the same username as the original one, hence the IntegrityError.

I think you need to do it like this instead:

u = CustomUser.objects.get(username='django')
u.delete()
u.channel = c2
u.save()
