Building The Model

First we’ll build the model that will handle the credential data of the registering users.

[models.py]

import datetime 

from flask.ext.login import UserMixin
from peewee import *

DATABASE = SqliteDatabase('social.db')

class User(UserMixin, Model):
	username = CharField(unique=True)
	email = CharField(unique=True)
	password = CharField(max_length=100)
	joined_at = DateTimeField(default=datetime.datetime.now)
	is_admin = BooleanField(default=False)

	class Meta:
		database = DATABASE
		order_by = ('-joined_at',)

order_by = (‘-joined_at’,)
Orders registered users when listing them by the order of their joining date, new first descending to old.

Flask-Login

To use this great package, you first need to install it.

pip install flask-login

flask-login
A package that handles user sessions. For now we’re only going to use one of its functionalities: UserMixin.

UserMixin
Provides us with a few properties about the user’s login status that we will make use of later, and they are:
is_authenticated, is_active, is_anonymous, get_id()

from flask.ext.login import UserMixin
Imports UserMixin from the flask-login package, which in the Flask echo-system as all packages is installed to this ext module, which stands for External Area.

class User( UserMixin, Model ):
UserMixins must be inherited first, then the Model.
