![]() I liked how in factoryboy, for a given Factory you could call a method attributes() and get a dict back, good for use with dataset.But whats great about mixer is it helps you be DRY because of how it can do so much on-the-fly. Django + Factory Boy: Use Trait to create other factory objects. However, it is sometimes useful to force a given value to the counter, for instance to ensure that tests are properly reproducible. Supporting anecdote - why I chose mixer.I was drawn to factoryboy initially. import uuid from factory.django import DjangoModelFactory from factory.faker import Faker from factory import Sequence class SectorFactory. It is possible with the default Python random iterator, but this generates a value on declaration time and so every factory object will have the same random value. A common pattern with factoryboy is to use a factory.Sequence declaration to provide varying values to attributes declared as unique. The app source directory contains all of the actual Python code and other resources. For example:Ä®rror TypeError: 'Fuzzåhoice' object does not support indexing Keep in mind that each piece of functionality is entirely optional. Getting the first item of the tuple is not possible. Type = åhoice(IceCreamProduct.PRODUCT_TYPES)Ä®rror TypeError: int() argument must be a string, a bytes-like object or a number, not 'tuple' For example:įactories class IceCreamProductFactory(): It can not take the first item of the chosen iterable. To generate a random value in Factory Boy for choices I would utilise åhoice, but this only chooses an iterable of 2 items. Detailed logging is available through the factory. Debugging factoryboy Debugging factoryboy can be rather complex due to the long chains of calls. Type = models.PositiveSmallIntegerField('Type', choices=PRODUCT_TYPES, default=0) factoryboy supports active Python versions as well as PyPå. Models class IceCreamProduct(models.Model): model_type having: model_a = SubFactory(ModelAFactory, type = factory.LazyAttribute(lambda o: '%d' % o.model_type))ĪttributeError: The parameter 'model_type' is unknown.When a field in a Django model has the option choices, see Django choices field option, it utilises an iterable containing iterables of 2 items to define which values are allowed. class PlacesFactory (DjangoModelFactory): class Meta: model Places site factory.SubFactory (SiteFactory) factory.

The subclassed Factory will inherit all declarations from its parent, and update them with its own declarations: class UserFactory(factory.Factory): class Meta: model base.

Once a base factory has been defined for a given class, alternate versions can be easily defined through subclassing. Type = models.PositiveSmallIntegerField(choices=TYPE_CHOICES) Released: Project description factoryboy integration with the pytest runner pytest-factoryboy makes it easy to combine factory approach to the test setup with the dependency injection, heart of the pytest fixtures.
