I don't understand what's wrong with this code. It asks me to add the Meta class to Relationship, but doesn't work.

"Finally, add the class Meta to the Relationship model. The database should point to DATABASE. You also need to add indexes to the model to make it unique. The index should be a tuple with a tuple of the two foreign key fields and True."

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='')

    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')
    created_at = DateTimeField(default=datetime.datetime.now)

    class Meta:
        indexes = (("from_user", "to_user"), True)
        database = DATABASE

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()

Haha, I found out what was happening. If anyone sees this question and having a hard time, add a comma after True and closed parentheses.

class Meta: indexes = ( (("from_user", "to_user"), True), ) database = DATABASE
