Changelog

Sourced from factory-boy's changelog.

3.3.0 (2023-07-19)

New:

- :issue:`366`: Add :class:`factory.django.Password` to generate Django :class:`~django.contrib.auth.models.User`
  passwords.
- :issue:`304`: Add :attr:`~factory.alchemy.SQLAlchemyOptions.sqlalchemy_session_factory` to dynamically
  create sessions for use by the :class:`~factory.alchemy.SQLAlchemyModelFactory`.
- Add support for Django 4.0
- Add support for Django 4.1
- Add support for Python 3.10
- Add support for Python 3.11

Bugfix:

- Make :meth:`~factory.django.mute_signals` mute signals during post-generation.

: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.

Deprecated:

- :class:`~factory.django.DjangoModelFactory` will stop issuing a second call to
  :meth:`~django.db.models.Model.save` on the created instance when :ref:`post-generation-hooks` return a value.
To help with the transition, :class:factory.django.DjangoModelFactory._after_postgeneration raises a
:class:DeprecationWarning when calling :meth:~django.db.models.Model.save. Inspect your
:class:~factory.django.DjangoModelFactory subclasses:


If the :meth:~django.db.models.Model.save call is not needed after :class:~factory.PostGeneration, set
:attr:factory.django.DjangoOptions.skip_postgeneration_save to True in the factory meta.


Otherwise, the instance has been modified by :class:~factory.PostGeneration hooks and needs to be
:meth:~django.db.models.Model.save\ d. Either:

call :meth:django.db.models.Model.save in the :class:~factory.PostGeneration hook that modifies the
instance, or
override :class:~factory.django.DjangoModelFactory._after_postgeneration to
:meth:~django.db.models.Model.save the instance.

Removed:

- Drop support for Django 2.2
- Drop support for Django 3.0
- Drop support for Django 3.1
- Drop support for Python 3.6

3.2.1 (2021-10-26)
