probably this isn't the right way to do the PartSerializer

[hcientist]

So i added a field to the model and serializer, but I think I done bad because when trying to migrate from scratch (brand new db) i get the following which seems to come from teleband/musics/migrations/0016_seed_pieces_later.py (perhaps due to the PartCreateSerializer or its create function?):

Traceback (most recent call last):

The above exception was the direct cause of the following exception:
