Python Build a Social Network with Flask How to Win Friends Related Users

Anyone with an idea on where i'm getting wrong

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"..

models.py
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='')
    user = ForeignKeyField(
        rel_model=User,
        related_name='new'
    )

    content = TextField()


    class Meta:
        database = DATABASE
        order_by('timestamps')

class Relationship(Model):
    from_user = ForeignKeyField(User, related_name='relationships')
    to_user = ForeignKeyField(User, related_name='new')

    @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()

You were on the right track. A typo fixes Task 2. Also, unrelated classmethod should be removed.

class Relationship(Model):
    from_user = ForeignKeyField(User, related_name='relationships')  # Task 1 correct
    to_user = ForeignKeyField(User, related_name='related_to')  # changed related_name to 'related_to' fixes Task 2

    # This block should not be included in this class.
    # @classmethod
    # def new(cls, email, password):
    #     cls.create(
    #         email=email,
    #         password=generate_password_hash(password)
    #     )

Post back if you need more help. Good Luck on Task 3!
