django-fakery 0.0.2

A model instances generator for Django

An easy-to-use implementation of Creation Methods for Django, backed by Faker.

django_fakery will try to guess the field’s value based on the field’s name and type.

QuickStart

from django_fakery.factory import factory

factory.make('auth.User', quantity=4)

Lazies

You can refer to the created instance’s own field by using Lazy objects.

For example, if you’d like to create user with email as username, and have them always match, you could do:

from django_fakery.lazy import Lazy

factory.make(
    'auth.User',
    username=Lazy('email')
)

Blueprints

from django_fakery.blueprint import Blueprint

user = Blueprint('auth.User')

user.make(quantity=10)

If you want to ensure uniqueness when generating multiple objects, you can use a lambda function.

In this example, n is the iteration number, and f is an instance of faker:

user = Blueprint(
    'auth.User',
    fields={
        'username': lambda n, f: 'user_%s' % n,
    }
)

For convenience, when the value is a string, you can simply pass a formatting string:

user = Blueprint(
    'auth.User',
    fields={
        'username': 'user_%(n)s',
    }
)

Blueprints can refer other blueprints:

pizza = Blueprint(
    'food.Pizza',
    fields={
        'chef': user,
    }
)

Seeding the faker

from django_fakery.factory import Factory

factory = Factory()

factory.seed(1234)

factory.make('auth.User', fields={
    'username': 'regularuser'
}, seed=1234, quantity=4)

from django_fakery.factory import factory

factory.make('auth.User', fields={
    'username': 'regularuser'
}, seed=1234, quantity=4)
