# Django REST framework 3.4
|
|
|
|
The 3.4 release is the first in a planned series that will be addressing schema
|
|
generation, hypermedia support, API clients, and finally realtime support.
|
|
|
|
---
|
|
|
|
## Funding
|
|
|
|
The 3.4 release has been made possible a recent [Mozilla grant][moss], and by our
|
|
[collaborative funding model][funding]. If you use REST framework commercially, and would
|
|
like to see this work continue, we strongly encourage you to invest in its
|
|
continued development by **[signing up for a paid plan][funding]**.
|
|
|
|
The initial aim is to provide a single full-time position on REST framework.
|
|
Right now we're over 60% of the way towards achieving that.
|
|
*Every single sign-up makes a significant impact.*

## Schemas & client libraries
|
|
|
|
REST framework 3.4 brings built-in support for generating API schemas.
|
|
|
|
We provide this support by using [Core API][core-api], a Document Object Model
|
|
for describing APIs.
|
|
|
|
Because Core API represents the API schema in an format-independent
|
|
manner, we're able to render the Core API `Document` object into many different
|
|
schema formats, by allowing the renderer class to determine how the internal
|
|
representation maps onto the external schema format.
|
|
|
|
This approach should also open the door to a range of auto-generated API
|
|
documentation options in the future, by rendering the `Document` object into
|
|
HTML documentation pages.
|
|
|
|
Alongside the built-in schema support, we're also now providing the following:
|
|
|
|
* A [command line tool][command-line-client] for interacting with APIs.
|
|
* A [Python client library][client-library] for interacting with APIs.
|
|
|
|
These API clients are dynamically driven, and able to interact with any API
|
|
that exposes a supported schema format.
|
|
|
|
Dynamically driven clients allow you to interact with an API at an application
|
|
layer interface, rather than a network layer interface, while still providing
|
|
the benefits of RESTful Web API design.
|
|
|
|
We're expecting to expand the range of languages that we provide client libraries
|
|
for over the coming months.
|
|
|
|
Further work on maturing the API schema support is also planned, including
|
|
documentation on supporting file upload and download, and improved support for
|
|
documentation generation and parameter annotation.
|
|
|
|
---
|
|
|
|
Current support for schema formats is as follows:
|
|
|
|
Name | Support | PyPI package
|
|
---------------------------------|-------------------------------------|--------------------------------
|
|
[Core JSON][core-json] | Schema generation & client support. | Built-in support in `coreapi`.
|
|
[Swagger / OpenAPI][swagger] | Schema generation & client support. | The `openapi-codec` package.
|
|
[JSON Hyper-Schema][hyperschema] | Currently client support only. | The `hyperschema-codec` package.
|
|
[API Blueprint][api-blueprint] | Not yet available. | Not yet available.
|
|
|
|
---
|
|
|
|
You can read more about any of this new functionality in the following:
|
|
|
|
* New tutorial section on [schemas & client libraries][tut-7].
|
|
* Documentation page on [schema generation][schema-generation].
|
|
* Topic page on [API clients][api-clients].
|
|
|
|
It is also worth noting that Marc Gibbons is currently working towards a 2.0 release of
|
|
the popular Django REST Swagger package, which will tie in with our new built-in support.
|
|

## Supported versions
|
|
|
|
The 3.4.0 release adds support for Django 1.10.
|
|
|
|
The following versions of Python and Django are now supported:
|
|
|
|
* Django versions 1.8, 1.9, and 1.10.
|
|
* Python versions 2.7, 3.2(\*), 3.3(\*), 3.4, 3.5.
|
|
|
|
(\*) Note that Python 3.2 and 3.3 are not supported from Django 1.9 onwards.

|
## Deprecations and changes
|
|
|
|
The 3.4 release includes very limited deprecation or behavioral changes, and
|
|
should present a straightforward upgrade.
|
|
|
|
### Use fields or exclude on serializer classes.
|
|
|
|
The following change in 3.3.0 is now escalated from "pending deprecation" to
|
|
"deprecated". Its usage will continue to function but will raise warnings:
|
|
|
|
`ModelSerializer` and `HyperlinkedModelSerializer` should include either a `fields`
|
|
option, or an `exclude` option. The `fields = '__all__'` shortcut may be used
|
|
to explicitly include all fields.
|
|
|
|
### Microsecond precision when returning time or datetime.
|
|
|
|
Using the default JSON renderer and directly returning a `datetime` or `time`
|
|
instance will now render with microsecond precision (6 digits), rather than
|
|
millisecond precision (3 digits). This makes the output format consistent with the
|
|
default string output of `serializers.DateTimeField` and `serializers.TimeField`.
|
|
|
|
This change *does not affect the default behavior when using serializers*,
|
|
which is to serialize `datetime` and `time` instances into strings with
|
|
microsecond precision.
|
|
|
|
The serializer behavior can be modified if needed, using the `DATETIME_FORMAT`
|
|
and `TIME_FORMAT` settings.
|
|
|
|
The renderer behavior can be modified by setting a custom `encoder_class`
|
|
attribute on a `JSONRenderer` subclass.
|
|
|
|
### Relational choices no longer displayed in OPTIONS requests.
|
|
|
|
Making an `OPTIONS` request to views that have a serializer choice field
|
|
will result in a list of the available choices being returned in the response.
|
|
|
|
In cases where there is a relational field, the previous behavior would be
|
|
to return a list of available instances to choose from for that relational field.
|
|
|
|
In order to minimise exposed information the behavior now is to *not* return
|
|
choices information for relational fields.
|
|
|
|
If you want to override this new behavior you'll need to [implement a custom
|
|
metadata class][metadata].
|
|
|
|
See [issue #3751][gh3751] for more information on this behavioral change.
