[Fixed]-Django bulk create objects from QuerySet

✅

This is more efficient than your call because it uses bulk_create, which invokes just one SQL bulk create operation, as opposed to one create per object; also, it is much more elegant:

ModelB.objects.bulk_create([ ModelB(**q) for q in data ])

As to how this works, the double asterisk unpacks a dictionary (or dictionary-like object) into keyword arguments to a Python function.
