django-simple-factory 0.0.2

A simple factory for Django Applications

Django Simple Factory

A simple factory implementation built upon Faker.

Installation

pip install django-simple-factory

Usage

To use factories, create a factories.py inside of a Django app. Then subclass the django_simple_factory.factories.Factory class. To define the model generation, override the definition method.

from django_simple_factory.factories import Factory
from posts import models

class PostFactory(Factory):
    model = models.Post

    def definition(self):
        return {
            "title": self.faker.word(),
            "content": self.faker.text(),
        }

class CommentFactory(Factory):
    model = "comments.Comment" # You can provide a model string

    def definition(self):
        return {
            "content": self.faker.text(),
            "post": PostFactory() # You can provide either a factory instance or a factory string (e.g)
        }

To use these models, instaniate the factories, then call either make or create.

post_factory = PostFactory()
post_factory.make() # Does not persist
post_factory.create() # Does Persist

To enable easier testing, a FactoryTestMixin has been included that enables rich definition of factories.

from django_simple_factory.mixins import FactoryTestMixin
from django.test import TestCase
from posts import models

class PostTest(FactoryTestMixin, TestCase):
    factories = ["posts.PostFactory"]

    def test_post_creation(self):
        post = self.factories[models.Post].create()
        ...

API

django_simple_factory.factories.Factory

The primary class of the package, factories allow for simple and easy testing of Django models.

Method	Description
configure_faker	A hook that enables the configuration of the factory's faker instance. Each factory contains its own separate faker instance.
get_factory	A class method that enables the discovery of a Factory (e.g. Factory.get_factory("posts.PostFactory")). The string passed in mimics the models access. To access a factory via string it should be of the form <app_name>.<factory_name>.
make	Make is one of the primary methods for creating an model. make does not persist the model, rather it just gives an instance. To override the generated values, provide keyword arguments to the method. If you want to override related object creation, provide a keyword argument with a dictionary (e.g. post_factory.make(user={"email": "[e-mail]"}))
create	Create is very much like make, except it does persist the model.
