I am getting this Error message. I'm not sure what's wrong.
import datetime
from flask.ext.bcrypt import generate_password_hash
from flask.ext.login import UserMixin
from peewee import *
DATABASE = SqliteDatabase(':memory:')
class User(UserMixin, Model):
email = CharField(unique=True)
password = CharField(max_length=100)
join_date = DateTimeField(default=datetime.datetime.now)
bio = CharField(default='')
class Relationship(Model):
from_user = ForeignKeyField(User, related_name='relationships')
to_user = ForeignKeyField(User, related_name='related_to')
class Meta:
database = DATABASE
@classmethod
def new(cls, email, password):
cls.create(
email=email,
password=generate_password_hash(password)
)
class LunchOrder(Model):
order = TextField()
date = DateField()
user = ForeignKeyField(User, related_name="orders")
def initialize():
DATABASE.connect()
DATABASE.create_tables([User, LunchOrder], safe=True)
DATABASE.close()

36,427 PointsI'm not sure if this is your material issue, but I spot one problem with the code right off the bat. Python is very unforgiving about improper indentation since that's how code blocks are designated (and not with curly braces like in JavaScript).
So this part of your code:
class Relationship(Model):
from_user = ForeignKeyField(User, related_name='relationships')
to_user = ForeignKeyField(User, related_name='related_to')
should be changed to:
class Relationship(Model):
from_user = ForeignKeyField(User, related_name='relationships')
to_user = ForeignKeyField(User, related_name='related_to')
Keep in mind that all indentation in Python is precisely 4 spaces (of the child/nested code relative to the parent/nesting code).
Please let me know of that was the problem.
I hope that helps. Happy coding!

36,427 PointsSorry, I missed a bit of the directions for (objective of) the challenge.
The Relationship class/Model should be declared OUTSIDE the User class/model
This passes:
from flask.ext.bcrypt import generate_password_hash
from flask.ext.login import UserMixin
from peewee import *
DATABASE = SqliteDatabase(':memory:')
class User(UserMixin, Model):
email = CharField(unique=True)
password = CharField(max_length=100)
join_date = DateTimeField(default=datetime.datetime.now)
bio = CharField(default='')
class Meta:
database = DATABASE
@classmethod
def new(cls, email, password):
cls.create(
email=email,
password=generate_password_hash(password)
)
class Relationship(Model):
from_user = ForeignKeyField(User, related_name='relationships')
to_user = ForeignKeyField(User, related_name='related_to')
class LunchOrder(Model):
order = TextField()
date = DateField()
user = ForeignKeyField(User, related_name="orders")
def initialize():
DATABASE.connect()
DATABASE.create_tables([User, LunchOrder], safe=True)
DATABASE.close()
Notice that there are always two blank lines between class declarations - its best-practice syntax.
I hope that helps. Happy coding!
