------------------

*New:*

    - Add support for Django 3.2

*Bugfix:*

    - Do not override signals receivers registered in a :meth:`~factory.django.mute_signals` context.

    - :issue:`775`: Change the signature for :meth:`~factory.alchemy.SQLAlchemyModelFactory._save` and
      :meth:`~factory.alchemy.SQLAlchemyModelFactory._get_or_create` to avoid argument names clashes with a field named
      ``session``.


3.2.0 (2020-12-28)
------------------

*New:*

    - Add support for Django 3.1
    - Add support for Python 3.9

*Removed:*

    - Drop support for Django 1.11. This version `is not maintained anymore <https://www.djangoproject.com/download/#supported-versions>`__.
    - Drop support for Python 3.5. This version `is not maintained anymore <https://devguide.python.org/devcycle/#end-of-life-branches>`__.

*Deprecated:*

    - :func:`factory.use_strategy`. Use :attr:`factory.FactoryOptions.strategy` instead.
      The purpose of :func:`~factory.use_strategy` duplicates the factory option. Follow :pep:`20`: *There should be
      one-- and preferably only one --obvious way to do it.*

      :func:`~factory.use_strategy()` will be removed in the next major version.

*Bug fix:*

    - :issue:`785` :issue:`786` :issue:`787` :issue:`788` :issue:`790` :issue:`796`: Calls to :class:`factory.Faker`
      and :class:`factory.django.FileField` within a :class:`~factory.Trait` or :class:`~factory.Maybe` no longer lead to
      a ``KeyError`` crash.


3.1.0 (2020-10-02)
------------------

*New:*

    - Allow all types of declarations in :class:`factory.Faker` calls - enables references to other faker-defined attributes.


3.0.1 (2020-08-13)
------------------

*Bug fix:*

    - :issue:`769`: Fix ``import factory; factory.django.DjangoModelFactory`` and similar calls.

    - Fix :class:`~factory.fuzzy.FuzzyFloat` to return a 15 decimal digits precision float by default
    - :issue:`451`: Restore :class:`~factory.django.FileField` to a

*New:*

    - :issue:`397`: Allow a :class:`factory.Maybe` to contain a :class:`~factory.PostGenerationDeclaration`.
      This also applies to :class:`factory.Trait`, since they use a :class:`factory.Maybe` declaration internally.

.. _v2.9.2:

2.9.2 (2017-08-03)
------------------

*Bug fix:*

    - Fix declaration corruption bug when a factory defined `foo__bar__baz=1` and a caller
      provided a `foo__bar=x` parameter at call time: this got merged into the factory's base
      declarations.

.. _v2.9.1:

2.9.1 (2017-08-02)
------------------

*Bug fix:*

    - Fix packaging issues (see https://github.com/zestsoftware/zest.releaser/issues/212)
    - Don't crash when debugging PostGenerationDeclaration

.. _v2.9.0:

2.9.0 (2017-07-30)
------------------

This version brings massive changes to the core engine, thus reducing the number of
corner cases and weird behaviors.

*New:*

    - :issue:`275`: `factory.fuzzy` and `factory.faker` now use the same random seed.
    - Add :class:`factory.Maybe`, which chooses among two possible declarations based
      on another field's value (powers the :class:`~factory.Trait` feature).
    - :class:`~factory.PostGenerationMethodCall` only allows to pass one positional argument; use keyword arguments for
      extra parameters.

*Deprecation:*

    - `factory.fuzzy.get_random_state` is deprecated, `factory.random.get_random_state` should be used instead.
    - `factory.fuzzy.set_random_state` is deprecated, `factory.random.set_random_state` should be used instead.
    - `factory.fuzzy.reseed_random` is deprecated, `factory.random.reseed_random` should be used instead.

.. _v2.8.1:

2.8.1 (2016-12-17)
------------------

*Bug fix:*

    - Fix packaging issues.


.. _v2.8.0:

2.8.0 (2016-12-17)
------------------

*New:*

    - :issue:`240`: Call post-generation declarations in the order they were declared,
      thanks to `Oleg Pidsadnyi <https://github.com/olegpidsadnyi>`_.
    - :issue:`309`: Provide new options for SQLAlchemy session persistence

*Bug fix:*

    - :issue:`334`: Adjust for the package change in ``faker``


.. _v2.7.0:

2.7.0 (2016-04-19)
------------------

*New:*

    - :pr:`267`: Add :class:`factory.LazyFunction` to remove unneeded lambda parameters,
      thanks to `Hervé Cauwelier <https://github.com/bors-ltd>`_.
    - :issue:`251`: Add :ref:`parameterized factories <parameters>` and :class:`traits <factory.Trait>`
    - :pr:`256`, :pr:`292`: Improve error messages in corner cases

*Removed:*

	- :pr:`278`: Formally drop support for Python2.6

.. warning:: Version 2.7.0 moves all error classes to
             `factory.errors`. This breaks existing import statements
             for any error classes except those importing
             `FactoryError` directly from the `factory` module.

.. _v2.6.1:

2.6.1 (2016-02-10)
------------------

*New:*

    - :pr:`262`: Allow optional forced flush on SQLAlchemy, courtesy of `Minjung <https://github.com/Minjung>`_.

.. _v2.6.0:

2.6.0 (2015-10-20)
------------------

    - Add :attr:`factory.FactoryOptions.rename` to help handle conflicting names (:issue:`206`)
    - Add support for random-yet-realistic values through `fake-factory <https://pypi.org/project/fake-factory/>`_,
      through the :class:`factory.Faker` class.
    - :class:`factory.Iterator` no longer begins iteration of its argument at import time,
      thus allowing to pass in a lazy iterator such as a Django queryset
      (i.e ``factory.Iterator(models.MyThingy.objects.all())``).
    - Simplify imports for ORM layers, now available through a simple ``factory`` import,
      at ``factory.alchemy.SQLAlchemyModelFactory`` / ``factory.django.DjangoModelFactory`` / ``factory.mongoengine.MongoEngineFactory``.

*Bug fix:*

    - :issue:`201`: Properly handle custom Django managers when dealing with abstract Django models.
    - :issue:`212`: Fix :meth:`factory.django.mute_signals` to handle Django's signal caching
    - :issue:`228`: Don't load :func:`django.apps.apps.get_model()` until required
    - :pr:`219`: Stop using :meth:`mogo.model.Model.new()`, deprecated 4 years ago.

.. _v2.5.2:

------------------

*Bug fix:*

    - Add support for Django 1.7/1.8
    - Add support for mongoengine>=0.9.0 / pymongo>=2.1

    - Allow passing declarations (e.g :class:`~factory.Sequence`) as parameters to :class:`~factory.django.FileField`
      and :class:`~factory.django.ImageField`.

.. _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`).

*Bug fix:*

    - 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/FactoryBoy/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`` occurrences; the files containing other attributes to rename can be found with ``grep -R  FACTORY .``


.. _v2.4.1:

2.4.1 (2014-06-23)
------------------

*Bug fix:*

    - 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>`_ (:pr:`120`)

    - 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.ABSTRACT_FACTORY` to :attr:`~factory.FactoryOptions.abstract`
      * Rename :attr:`~factory.Factory.FACTORY_STRATEGY` to :attr:`~factory.FactoryOptions.strategy`

      * Rename :attr:`~factory.Factory.FACTORY_HIDDEN_ARGS` to :attr:`~factory.FactoryOptions.exclude`

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

      discovered by `mbertheau <https://github.com/mbertheau>`_ (:issue:`123`) and `strycore <https://github.com/strycore>`_ (:pr:`127`)

.. _v2.3.0:

2.3.0 (2013-12-25)

*New:*

    - The :class:`~factory.django.DjangoModelFactory` now supports the ``FACTORY_FOR = 'myapp.MyModel'``

    - Add :meth:`factory.debug()` helper for easier backtrace analysis
    - Adding factory support for mongoengine with :class:`~factory.mongoengine.MongoEngineFactory`.

.. _v2.1.2:

2.1.2 (2013-08-14)
------------------

*New:*

    - The :class:`~factory.Factory.ABSTRACT_FACTORY` keyword is now optional, and automatically set

    - Usage of :meth:`~factory.Factory.set_creation_function` and :meth:`~factory.Factory.set_building_function`
      are now deprecated

.. _changelog-1-3-0-upgrading:

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 automatic 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``
