i have tried and tried a million times but it keeps saying indentation error, and if it is inline with the attributes it gives an error saying class meta is not an attribute of challenge. what should i do.
from peewee import *
db = SqliteDatabase('challenges.db')
class Challenge:
name = CharField(max_length=100)
language = CharField(max_length=100)
class Meta:
database = db

Treehouse Moderator 68,423 PointsLiana Moleni, you are correct in that, for your code, Meta is not an attribute of Challenge. This is because Challenge has no inherited classes, so is type object. The key missing part is inheriting from peewee.Model which provides the Meta attribute:
from peewee import *
db = SqliteDatabase('challenges.db')
class Challenge(Model): #<- added Model inheritance
name = CharField(max_length=100)
language = CharField(max_length=100)
class Meta: #<-- corrected indentation
database = db
So Kenneth Love's challenge is correct as written.

from peewee import *
db = SqliteDatabase('challenges.db')
class Challenge:
name = CharField(max_length=100)
language = CharField(max_length=100)
class _meta:
database = db
If you see the class nested is '_meta', but in the instructions and the video it was 'Meta'.

Treehouse Guest TeacherIt's not a bug, AFAICT, but just how Peewee exposes the Meta class for a model. Both Meta and _meta are allowed.
But, as per Python's conventions, you don't want to rely on methods/attributes/properties/etc that start with an underscore. That generally implies that the thing isn't guaranteed to work the exact same way forever. The Meta object, though, without having the underscore, is expected to be predictable from now on.
