ChangeLog

2.4.1 (2014-06-23)

Bugfix:

• Fix overriding deeply inherited attributes (set in one factory, overridden in a subclass, used in a sub-sub-class).

2.4.0 (2014-06-21)

New:

• Add support for factory.fuzzy.FuzzyInteger.step, thanks to ilya-pirogov (issue #120)
• Add mute_signals() decorator to temporarily disable some signals, thanks to ilya-pirogov (issue #122)
• Add FuzzyFloat (issue #124)
• Declare target model and other non-declaration fields in a class Meta section.

Deprecation:

• Use of FACTORY_FOR and other FACTORY class-level attributes is deprecated and will be removed in 2.5. Those attributes should now declared within the class Meta attribute:

  For factory.Factory:

  • Rename FACTORY_FOR to model
  • Rename FACTORY_FOR to model
  • Rename ABSTRACT_FACTORY to abstract
  • Rename FACTORY_STRATEGY to strategy
  • Rename FACTORY_ARG_PARAMETERS to inline_args
  • Rename FACTORY_HIDDEN_ARGS to exclude

  For factory.django.DjangoModelFactory:

  • Rename FACTORY_DJANGO_GET_OR_CREATE to django_get_or_create

  For factory.alchemy.SQLAlchemyModelFactory:

  • Rename FACTORY_SESSION to sqlalchemy_session

2.3.1 (2014-01-22)

Bugfix:

• Fix badly written assert containing state-changing code, spotted by chsigi (issue #126)
• Don’t crash when handling objects whose __repr__ is non-pure-ascii bytes on Py2, discovered by mbertheau (issue #123) and strycore (issue #127)

2.3.0 (2013-12-25)

New:

• Add FuzzyText, thanks to jdufresne (issue #97)
• Add FuzzyDecimal, thanks to thedrow (issue #94)
• Add support for EmbeddedDocument, thanks to imiric (issue #100)

2.2.1 (2013-09-24)

Bugfix:

• Fixed sequence counter for DjangoModelFactory when a factory inherits from another factory relating to an abstract model.

2.2.0 (2013-09-24)

Bugfix:

• Removed duplicated SQLAlchemyModelFactory lurking in factory (issue #83)
• Properly handle sequences within object inheritance chains. If FactoryA inherits from FactoryB, and their associated classes share the same link, sequence counters will be shared (issue #93)
• Properly handle nested SubFactory overrides

New:

• The DjangoModelFactory now supports the FACTORY_FOR = 'myapp.MyModel' syntax, making it easier to shove all factories in a single module (issue #66).
• Add factory.debug() helper for easier backtrace analysis
• Adding factory support for mongoengine with MongoEngineFactory.

2.1.2 (2013-08-14)

New:

• The ABSTRACT_FACTORY keyword is now optional, and automatically set to True if neither the Factory subclass nor its parent declare the FACTORY_FOR attribute (issue #74)

2.1.1 (2013-07-02)

Bugfix:

• Properly retrieve the color keyword argument passed to ImageField

2.1.0 (2013-06-26)

New:

• Add FuzzyDate thanks to saulshanabrook
• Add FuzzyDateTime and FuzzyNaiveDateTime.
• Add a factory_parent attribute to the LazyStub passed to LazyAttribute, in order to access fields defined in wrapping factories.
• Move DjangoModelFactory and MogoFactory to their own modules (factory.django and factory.mogo)
• Add the reset_sequence() classmethod to Factory to ease resetting the sequence counter for a given factory.
• Add debug messages to factory logger.
• Add a reset() method to Iterator (issue #63)
• Add support for the SQLAlchemy ORM through SQLAlchemyModelFactory (issue #64, thanks to Romain Commandé)
• Add factory.django.FileField and factory.django.ImageField hooks for related Django model fields (issue #52)

Bugfix

• Properly handle non-integer pks in DjangoModelFactory (issue #57).
• Disable RelatedFactory generation when a specific value was passed (issue #62, thanks to Gabe Koscky)

Deprecation:

• Rename RelatedFactory‘s name argument to factory_related_name (See issue #58)

2.0.2 (2013-04-16)

New:

• When FACTORY_DJANGO_GET_OR_CREATE is empty, use Model.objects.create() instead of Model.objects.get_or_create.

2.0.1 (2013-04-16)

New:

• Don’t push defaults to get_or_create when FACTORY_DJANGO_GET_OR_CREATE is not set.

2.0.0 (2013-04-15)

New:

• Allow overriding the base factory class for make_factory() and friends.
• Add support for Python3 (Thanks to kmike and nkryptic)
• The default type for Sequence is now int
• Fields listed in FACTORY_HIDDEN_ARGS won’t be passed to the associated class’ constructor
• Add support for get_or_create in DjangoModelFactory, through FACTORY_DJANGO_GET_OR_CREATE.
• Add support for fuzzy attribute definitions.
• The Sequence counter can be overridden when calling a generating function
• Add Dict and List declarations (Closes issue #18).

Removed:

• Remove associated class discovery
• Remove InfiniteIterator and infinite_iterator()
• Remove CircularSubFactory
• Remove extract_prefix kwarg to post-generation hooks.
• Stop defaulting to Django’s Foo.objects.create() when “creating” instances
• Remove STRATEGY_*
• Remove set_building_function() / set_creation_function()

1.3.0 (2013-03-11)

Warning

This version deprecates many magic or unexplicit features that will be removed in v2.0.0.

Please read the Upgrading section, then run your tests with python -W default to see all remaining warnings.

New

• Global:

  • Rewrite the whole documentation
  • Provide a dedicated MogoFactory subclass of Factory

• The Factory class:

  • Better creation/building customization hooks at factory.Factory._build() and factory.Factory.create()
  • Add support for passing non-kwarg parameters to a Factory wrapped class through FACTORY_ARG_PARAMETERS.
  • Keep the FACTORY_FOR attribute in Factory classes

• Declarations:

  • Allow SubFactory to solve circular dependencies between factories
  • Enhance SelfAttribute to handle “container” attribute fetching
  • Add a getter to Iterator declarations
  • A Iterator may be prevented from cycling by setting its cycle argument to False
  • Allow overriding default arguments in a PostGenerationMethodCall when generating an instance of the factory
  • An object created by a DjangoModelFactory will be saved again after PostGeneration hooks execution

Pending deprecation

The following features have been deprecated and will be removed in an upcoming release.

• Declarations:

  • InfiniteIterator is deprecated in favor of Iterator
  • CircularSubFactory is deprecated in favor of SubFactory
  • The extract_prefix argument to post_generation() is now deprecated

• Factory:

  • Usage of set_creation_function() and set_building_function() are now deprecated
  • Implicit associated class discovery is no longer supported, you must set the FACTORY_FOR attribute on all Factory subclasses

Upgrading

This version deprecates a few magic or undocumented features. All warnings will turn into errors starting from v2.0.0.

In order to upgrade client code, apply the following rules:

• Add a FACTORY_FOR attribute pointing to the target class to each Factory, instead of relying on automagic associated class discovery
• When using factory_boy for Django models, have each factory inherit from DjangoModelFactory
• Replace factory.CircularSubFactory('some.module', 'Symbol') with factory.SubFactory('some.module.Symbol')
• Replace factory.InfiniteIterator(iterable) with factory.Iterator(iterable)
• Replace @factory.post_generation() with @factory.post_generation
• Replace factory.set_building_function(SomeFactory, building_function) with an override of the _build() method of SomeFactory
• Replace factory.set_creation_function(SomeFactory, creation_function) with an override of the _create() method of SomeFactory
