Re: IntegrityError at /add/ PRIMARY KEY must be unique

Not quite sure, but it seems like the save() method is being called twice so it is trying to create insert an entry with a primary key that already exists.

After adding data to database I have error (data is added correctly but displays an error):

Exception Type: IntegrityError at /add/  Exception Value: PRIMARY KEY must be unique

def add(request):  	if request.user.is_authenticated():  		user = request.user     		b = Product.objects.get(id=3)     		e = b.basket_set.create(name='basket_name', owner=user)      	e.save(force_insert=True)  	  	return render_to_response('basket.html')

How to fix it?
