When i'm trying to do simple get() it raises error:
Traceback (most recent call last):

It happened after i changed some of properties in model, and i can't
make migration.
Also why get() function checking required option of property? I had
some old data with None values in properties, witch in new version had
been checked as required. When i'm trying to access objects with such
properties with Null values i get error that this property required,
by i'm just trying to get, not put!
