Add a new model named Relationship. It should have a ForeignKeyField, related to User. The field should be named from_user with a related_name of "relationships".
i have been stuck here for days can someone kindly assist me with the full code .
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 Meta:
database = DATABASE
class Relationship(Model):
from_user = ForeignKeyField(User, related_name='relationships')
to_user = ForeignKeyField(User, related_name='related_to')
created_at = DateTimeField(default=datetime.datetime.now)
class Meta:
database = DATABASE
indexes = (
(('from_user','to_user'), True),
)
@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()

Treehouse TeacherThe relationship model should go outside the User class. Right now it is in the middle making the classmethod now relate to the relationship instead of the user class.
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 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")
class Relationship(Model):
from_user = ForeignKeyField(User, related_name="relationships")
def initialize():
DATABASE.connect()
DATABASE.create_tables([User, LunchOrder], safe=True)
DATABASE.close()
