ChangeLog
=========


.. _v2.5.1:

2.5.1 (master)
--------------

*Bugfix:*

    - Respect custom managers in :class:`~factory.django.DjangoModelFactory` (see :issue:`192`)

.. _v2.5.0:

2.5.0 (2015-03-26)
------------------

*New:*

    - Add support for getting/setting :mod:`factory.fuzzy`'s random state (see :issue:`175`, :issue:`185`).
    - Support lazy evaluation of iterables in :class:`factory.fuzzy.FuzzyChoice` (see :issue:`184`).
    - Support non-default databases at the factory level (see :issue:`171`)
    - Make :class:`factory.django.FileField` and :class:`factory.django.ImageField` non-post_generation, i.e normal fields also available in ``save()`` (see :issue:`141`).

*Bugfix:*

    - Avoid issues when using :meth:`factory.django.mute_signals` on a base factory class (see :issue:`183`).
    - Fix limitations of :class:`factory.StubFactory`, that can now use :class:`factory.SubFactory` and co (see :issue:`131`).


*Deprecation:*

    - Remove deprecated features from :ref:`v2.4.0`
    - Remove the auto-magical sequence setup (based on the latest primary key value in the database) for Django and SQLAlchemy;
      this relates to issues :issue:`170`, :issue:`153`, :issue:`111`, :issue:`103`, :issue:`92`, :issue:`78`. See https://github.com/rbarrois/factory_boy/commit/13d310f for technical details.

.. warning:: Version 2.5.0 removes the 'auto-magical sequence setup' bug-and-feature.
             This could trigger some bugs when tests expected a non-zero sequence reference.

Upgrading
"""""""""

.. warning:: Version 2.5.0 removes features that were marked as deprecated in :ref:`v2.4.0 <v2.4.0>`.

All ``FACTORY_*``-style attributes are now declared in a ``class Meta:`` section:

.. code-block:: python

    # Old-style, deprecated
    class MyFactory(factory.Factory):
        FACTORY_FOR = models.MyModel
        FACTORY_HIDDEN_ARGS = ['a', 'b', 'c']

    # New-style
    class MyFactory(factory.Factory):
        class Meta:
            model = models.MyModel
            exclude = ['a', 'b', 'c']

A simple shell command to upgrade the code would be:

.. code-block:: sh

    # sed -i: inplace update
    # grep -l: only file names, not matching lines
    sed -i 's/FACTORY_FOR =/class Meta:\n        model =/' $(grep -l FACTORY_FOR $(find . -name '*.py'))

This takes care of all ``FACTORY_FOR`` occurences; the files containing other attributes to rename can be found with ``grep -R  FACTORY .``


.. _v2.4.1:

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).

.. _v2.4.0:

2.4.0 (2014-06-21)
------------------

*New:*

    - Add support for :attr:`factory.fuzzy.FuzzyInteger.step`, thanks to `ilya-pirogov <https://github.com/ilya-pirogov>`_ (:issue:`120`)
    - Add :meth:`~factory.django.mute_signals` decorator to temporarily disable some signals, thanks to `ilya-pirogov <https://github.com/ilya-pirogov>`_ (:issue:`122`)
    - Add :class:`~factory.fuzzy.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:`class Meta <factory.FactoryOptions>` attribute:

      For :class:`factory.Factory`:

      * Rename :attr:`~factory.Factory.FACTORY_FOR` to :attr:`~factory.FactoryOptions.model`

      * Rename :attr:`~factory.Factory.FACTORY_FOR` to :attr:`~factory.FactoryOptions.model`
      * Rename :attr:`~factory.Factory.ABSTRACT_FACTORY` to :attr:`~factory.FactoryOptions.abstract`
      * Rename :attr:`~factory.Factory.FACTORY_STRATEGY` to :attr:`~factory.FactoryOptions.strategy`
      * Rename :attr:`~factory.Factory.FACTORY_ARG_PARAMETERS` to :attr:`~factory.FactoryOptions.inline_args`
      * Rename :attr:`~factory.Factory.FACTORY_HIDDEN_ARGS` to :attr:`~factory.FactoryOptions.exclude`

      For :class:`factory.django.DjangoModelFactory`:

      * Rename :attr:`~factory.django.DjangoModelFactory.FACTORY_DJANGO_GET_OR_CREATE` to :attr:`~factory.django.DjangoOptions.django_get_or_create`

      For :class:`factory.alchemy.SQLAlchemyModelFactory`:

      * Rename :attr:`~factory.alchemy.SQLAlchemyModelFactory.FACTORY_SESSION` to :attr:`~factory.alchemy.SQLAlchemyOptions.sqlalchemy_session`

    - Don't crash when handling objects whose __repr__ is non-pure-ascii bytes on Py2,
      discovered by `mbertheau <https://github.com/mbertheau>`_ (:issue:`123`) and `strycore <https://github.com/strycore>`_ (:issue:`127`)

.. _v2.3.0:

2.3.0 (2013-12-25)

      If FactoryA inherits from FactoryB, and their associated classes share the same link,
      sequence counters will be shared (:issue:`93`)
    - Properly handle nested :class:`~factory.SubFactory` overrides

*New:*

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

    - Move :class:`~factory.django.DjangoModelFactory` and :class:`~factory.mogo.MogoFactory`
      to their own modules (:mod:`factory.django` and :mod:`factory.mogo`)
    - Add the :meth:`~factory.Factory.reset_sequence` classmethod to :class:`~factory.Factory`
      to ease resetting the sequence counter for a given factory.

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
  :class:`~factory.Factory`, instead of relying on automagic associated class
  discovery
- When using factory_boy for Django models, have each factory inherit from
  :class:`~factory.django.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 :meth:`~factory.Factory._build` method of ``SomeFactory``
- Replace ``factory.set_creation_function(SomeFactory, creation_function)`` with
  an override of the :meth:`~factory.Factory._create` method of ``SomeFactory``
