# Django REST framework 3.6
|
|
|
|
The 3.6 release adds two major new features to REST framework.
|
|
|
|
1. Built-in interactive API documentation support.
|
|
2. A new JavaScript client library.
|
|
|
|
|
|
|

## Funding
|
|
|
|
The 3.6 release would not have been possible without our [backing from Mozilla](mozilla-grant.md) to the project, and 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]**.

## Interactive API documentation
|
|
|
|
REST framework's new API documentation supports a number of features:
|
|
|
|
* Live API interaction.
|
|
* Support for various authentication schemes.
|
|
* Code snippets for the Python, JavaScript, and Command Line clients.
|
|
|
|
The `coreapi` library is required as a dependancy for the API docs. Make sure
|
|
to install the latest version (2.3.0 or above). The `pygments` and `markdown`
|
|
libraries are optional but recommended.
|
|
|
|
To install the API documentation, you'll need to include it in your projects URLconf:
|
|
|
|
from rest_framework.documentation import include_docs_urls
|
|
|
|
API_TITLE = 'API title'
|
|
API_DESCRIPTION = '...'
|
|
|
|
urlpatterns = [
|
|
...
|
|
url(r'^docs/', include_docs_urls(title=API_TITLE, description=API_DESCRIPTION))
|
|
]
|
|
|
|
Once installed you should see something a little like this:
|
|
|
|
|
|
|
|
We'll likely be making further refinements to the API documentation over the
|
|
coming weeks. Keep in mind that this is a new feature, and please do give
|
|
us feedback if you run into any issues or limitations.
|
|
|
|
For more information on documenting your API endpoints see the ["Documenting your API"][api-docs] section.
|
|

|
## JavaScript client library
|
|
|
|
The JavaScript client library allows you to load an API schema, and then interact
|
|
with that API at an application layer interface, rather than constructing fetch
|
|
requests explicitly.
|
|
|
|
Here's a brief example that demonstrates:
|
|
|
|
* Loading the client library and schema.
|
|
* Instantiating an authenticated client.
|
|
* Making an API request using the client.
|
|
|
|
**index.html**
|
|
|
|
<html>
|
|
<head>
|
|
<script src="/static/rest_framework/js/coreapi-0.1.0.js"></script>
|
|
<script src="/docs/schema.js"></script>
|
|
<script>
|
|
const coreapi = window.coreapi
|
|
const schema = window.schema
|
|
|
|
// Instantiate a client...
|
|
let auth = coreapi.auth.TokenAuthentication({scheme: 'JWT', token: 'xxx'})
|
|
let client = coreapi.Client({auth: auth})
|
|
|
|
// Make an API request...
|
|
client.action(schema, ['projects', 'list']).then(function(result) {
|
|
alert(result)
|
|
})
|
|
</script>
|
|
</head>
|
|
</html>
|
|
|
|
The JavaScript client library supports various authentication schemes, and can be
|
|
used by your project itself, or as an external client interacting with your API.
|
|
|
|
The client is not limited to usage with REST framework APIs, although it does
|
|
currently only support loading CoreJSON API schemas. Support for Swagger and
|
|
other API schemas is planned.
|
|
|
|
For more details see the [JavaScript client library documentation][js-docs].
|
|
|
|
## Authentication classes for the Python client library
|
|
|
|
Previous authentication support in the Python client library was limited to
|
|
allowing users to provide explicit header values.
|
|
|
|
We now have better support for handling the details of authentication, with
|
|
the introduction of the `BasicAuthentication`, `TokenAuthentication`, and
|
|
`SessionAuthentication` schemes.
|
|
|
|
You can include the authentication scheme when instantiating a new client.
|
|
|
|
auth = coreapi.auth.TokenAuthentication(scheme='JWT', token='xxx-xxx-xxx')
|
|
client = coreapi.Client(auth=auth)
|
|
|
|
For more information see the [Python client library documentation][py-docs].

## Deprecations
|
|
|
|
### Updating coreapi
|
|
|
|
If you're using REST framework's schema generation, or want to use the API docs,
|
|
then you'll need to update to the latest version of coreapi. (2.3.0)
|
|
|
|
### Generating schemas from Router
|
|
|
|
The 3.5 "pending deprecation" of router arguments for generating a schema view, such as `schema_title`, `schema_url` and `schema_renderers`, have now been escalated to a
|
|
"deprecated" warning.
|
|
|
|
Instead of using `DefaultRouter(schema_title='Example API')`, you should use the `get_schema_view()` function, and include the view explicitly in your URL conf.
|
|
|
|
### DjangoFilterBackend
|
|
|
|
The 3.5 "pending deprecation" warning of the built-in `DjangoFilterBackend` has now
|
|
been escalated to a "deprecated" warning.
|
|
|
|
You should change your imports and REST framework filter settings as follows:
|
|
|
|
* `rest_framework.filters.DjangoFilterBackend` becomes `django_filters.rest_framework.DjangoFilterBackend`.
|
|
* `rest_framework.filters.FilterSet` becomes `django_filters.rest_framework.FilterSet`.
|
|
|

|
## What's next
|
|
|
|
There are likely to be a number of refinements to the API documentation and
|
|
JavaScript client library over the coming weeks, which could include some of the following:
|
|
|
|
* Support for private API docs, requiring login.
|
|
* File upload and download support in the JavaScript client & API docs.
|
|
* Comprehensive documentation for the JavaScript client library.
|
|
* Automatically including authentication details in the API doc code snippets.
|
|
* Adding authentication support in the command line client.
|
|
* Support for loading Swagger and other schemas in the JavaScript client.
|
|
* Improved support for documenting parameter schemas and response schemas.
|
|
* Refining the API documentation interaction modal.
|
|
|
|
Once work on those refinements is complete, we'll be starting feature work
|
|
on realtime support, for the 3.7 release.
