You'll need to be running Django 1.5, and it's worth keeping in mind that Django's Python 3 support is currently [considered experimental][django-python-3]. + +Django 1.6's Python 3 support is expected to be officially labeled as 'production-ready'. + +If you want to start ensuring that your own projects are Python 3 ready, we can highly recommend Django's [Porting to Python 3][porting-python-3] documentation. + +## Deprecation policy + +We've now introduced an official deprecation policy, which is in line with [Django's deprecation policy][django-deprecation-policy]. This policy will make it easy for you to continue to track the latest, greatest version of REST framework. + +The timeline for deprecation works as follows: + +* Version 2.2 introduces some API changes as detailed in the release notes. It remains fully backwards compatible with 2.1, but will raise `PendingDeprecationWarning` warnings if you use bits API that are due to be deprecated. These warnings are silent by default, but can be explicitly enabled when you're ready to start migrating any required changes. For example if you start running your tests using `python -Wd manage.py test`, you'll be warned of any API changes you need to make. + +* Version 2.3 will escalate these warnings to `DeprecationWarning`, which is loud by default. + +* Version 2.4 will remove the deprecated bits of API entirely. + +Note that in line with Django's policy, any parts of the framework not mentioned in the documentation should generally be considered private API, and may be subject to change. + +## Community + +As of the 2.2 merge, we've also hit an impressive milestone. The number of committers listed in [the credits][credits], is now at over **one hundred individuals**. Each name on that list represents at least one merged pull request, however large or small. + +Our [mailing list][mailing-list] and #restframework IRC channel are also very active, and we've got a really impressive rate of development both on REST framework itself, and on third party packages such as the great [django-rest-framework-docs][django-rest-framework-docs] package from [Marc Gibbons][marcgibbons]. + +## API changes + +The 2.2 release makes a few changes to the serializer fields API, in order to make it more consistent, simple, and easier to use. + +### Cleaner to-many related fields + +The `ManyRelatedField()` style is being deprecated in favor of a new `RelatedField(many=True)` syntax. + +For example, if a user is associated with multiple questions, which we want to represent using a primary key relationship, we might use something like the following: + + class UserSerializer(serializers.HyperlinkedModelSerializer): + questions = serializers.PrimaryKeyRelatedField(many=True) + + class Meta: + fields = ('username', 'questions') + +The new syntax is cleaner and more obvious, and the change will also make the documentation cleaner, simplify the internal API, and make writing custom relational fields easier. + +The change also applies to serializers. If you have a nested serializer, you should start using `many=True` for to-many relationships. For example, a serializer representation of an Album that can contain many Tracks might look something like this: + + class TrackSerializer(serializer.ModelSerializer): + class Meta: + model = Track + fields = ('name', 'duration') + + class AlbumSerializer(serializer.ModelSerializer): + tracks = TrackSerializer(many=True) + + class Meta: + model = Album + fields = ('album_name', 'artist', 'tracks') + +Additionally, the change also applies when serializing or deserializing data. For example to serialize a queryset of models you should now use the `many=True` flag. + + serializer = SnippetSerializer(Snippet.objects.all(), many=True) + serializer.data + +This more explicit behavior on serializing and deserializing data [makes integration with non-ORM backends such as MongoDB easier][564], as instances to be serialized can include the `__iter__` method, without incorrectly triggering list-based serialization, or requiring workarounds. + +The implicit to-many behavior on serializers, and the `ManyRelatedField` style classes will continue to function, but will raise a `PendingDeprecationWarning`, which can be made visible using the `-Wd` flag. + +### Cleaner optional relationships + +Serializer relationships for nullable Foreign Keys will change from using the current `null=True` flag, to instead using `required=False`. + +This is in line both with the rest of the serializer fields API, and with Django's `Form` and `ModelForm` API. + +Using `required` throughout the serializers API means you won't need to consider if a particular field should take `blank` or `null` arguments instead of `required`, and also means there will be more consistent behavior for how fields are treated when they are not present in the incoming data. + +The `null=True` argument will continue to function, and will imply `required=False`, but will raise a `PendingDeprecationWarning`. + +### Cleaner CharField syntax + +The `CharField` API previously took an optional `blank=True` argument, which was intended to differentiate between null CharField input, and blank CharField input. + +In keeping with Django's CharField API, REST framework's `CharField` will only ever return the empty string, for missing or `None` inputs. The `blank` flag will no longer be in use, and you should instead just use the `required=` flag. + +The `blank` keyword argument will continue to function, but will raise a `PendingDeprecationWarning`. + +[xordoquy]: https://github.com/xordoquy +[django-python-3]: https://docs.djangoproject.com/en/dev/faq/install/#can-i-use-django-with-python-3 +[porting-python-3]: https://docs.djangoproject.com/en/dev/topics/python3/ +[django-deprecation-policy]: https://docs.djangoproject.com/en/dev/internals/release-process/#internal-release-deprecation-policy +[credits]: http://django-rest-framework.org/topics/credits.html +[mailing-list]: https://groups.google.com/forum/?fromgroups#!forum/django-rest-framework +[django-rest-framework-docs]: https://github.com/marcgibbons/django-rest-framework-docs +[marcgibbons]: https://github.com/marcgibbons/ +[issues]: https://github.com/tomchristie/django-rest-framework/issues +[564]: https://github.com/tomchristie/django-rest-framework/issues/564 diff --git a/docs/topics/credits.md b/docs/topics/credits.md index a67a81690..ebca44916 100644 --- a/docs/topics/credits.md +++ b/docs/topics/credits.md @@ -101,6 +101,7 @@ The following people have helped make REST framework great. * Michał Jaworski - [swistakm] * Andrea de Marco - [z4r] * Fernando Rocha - [fernandogrd] +* Xavier Ordoquy - [xordoquy] Many thanks to everyone who's contributed to the project. @@ -237,3 +238,4 @@ You can also contact [@_tomchristie][twitter] directly on twitter.
