IntegrityError: challenge.name may not be NULL

Why am I getting this error? I tried to set the name argument to a value but that didn't work either.

crud.py 
from models import Challenge

def create_challenge(name, language, steps=1):
  Challenge.create()

create_challenge('tiff', 'python')

It looks like there is a validation on either the model or the database when you create a new Challenge instance. Right now you're trying to create a challenge without parameters which means the challenge would not have a name, language or steps initialized with it causing that validation error.
