django-seed 0.2.2

Seed your Django project with fake data

---

Django-seed uses the faker library to generate test data for your Django models. This has been “hard-forked” from django_faker in order to support newer versions of Python and Django

Django-seed allows you to write code to generate models, and seed your database with one simple manage.py command!

Installation

To install django-seed, use pip:

pip install django-seed

Or to install from source:

python setup.py install

Configuration

Add it to your installed apps in settings.py:

INSTALLED_APPS = (
    ...
    'django_seed',
)

Usage

Note: When seeding models with Foreign Keys, you need to make sure that those models are seeded first. For example, if a model in app A has a foreign key to a model in app B, you must seed app B first.

Using with command

With django-seed, you can seed your database with test data from the command line using the manage.py seed command.

Ex: Seed 15 of each model for the app api:

$ python manage.py seed api --number=15

That’s it! Now you have 15 of each model seeded into your database.

Using with code

django-seed provides methods to easily seed test databases for your Django models. To seed your database with Model instances, import Seed, get a seeder instance, and use the add_entity method.

Ex: seeding 5 Game and 10 Player objects:

from django_seed import Seed

seeder = Seed.seeder()

from myapp.models import Game, Player
seeder.add_entity(Game, 5)
seeder.add_entity(Player, 10)

inserted_pks = seeder.execute()

The seeder uses the name and column type to populate the Model with relevant data. If django-seed misinterprets a column name, you can still specify a custom function to be used for populating a particular column, by adding a third argument to the add_entity() method:

seeder.add_entity(Player, 10, {
    'score':    lambda x: random.randint(0,1000),
    'nickname': lambda x: seeder.faker.email(),
})
seeder.execute()

Django-seed does not populate auto-incremented primary keys, instead seeder.execute() returns the list of inserted PKs, indexed by class:

print inserted_pks
{
    <class 'faker.django.tests.Player'>: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
    <class 'faker.django.tests.Game'>: [1, 2, 3, 4, 5]
}

You may specify a different locale by passing it in the constructor of the seeder. Defaults to settings.LANGUAGE_CODE

seeder = Seed.seeder(locale='sv_SE')
seeder.faker.city()  # 'Västerås'

Tests

To run django tests in a django environment, first make sure you have the packages from requirement-test.txt installed, then run the following:

$ python runtests.py

or if you have django_seed in INSTALLED_APPS:

$ python manage.py test django_seed
