django-seed 0.1.1

Seed your Django project with fake data

Django-seed uses the faker library to generate test data for your Django models. This has been forked from django_faker because it is no longer in development and does not have support for Python 3

Not only will this version allow you to write code to generate models, it will allow you to seed your database with one simple manage.py command!

Installation

To install django-seed you can use pip:

pip install django-seed

Configuration

In django application settings.py:

INSTALLED_APPS = (
    ...
    'django_seed',
)

Usage

Using with command

One improvement that django-seed has over django-faker is the ability to seed your database from the command line. Using the manage.py seed command, you can do this automagically.

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, create a Seed 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, addming a third argument to add_entity():

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 autoincremented primary keys, instead django_seed.seeder.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]
}

Tests

Run django tests in a django environment:

$ python runtests.py

or if you have django_seed in INSTALLED_APPS:

$ python manage.py test django_seed
