# 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.

## API documentation
|
||||
## Interactive API documentation
|
||||
|
||||
...
|
||||
REST framework's new API documentation supports a number of features:
|
||||
|
||||
## JavaScript Client
|
||||
* Live API interaction.
|
||||
* Support for various authentication schemes.
|
||||
* Code snippets for the Python, JavaScript, and Command Line clients.
|
||||
|
||||
...
|
||||
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:
|
||||
|
||||
**TODO: Image**
|
||||
|
||||
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.

||||

||||

||||
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
|
||||
|
||||
...
|
||||
### DjangoFilterBackend
|
||||
|
||||
The functionality of the built-in `DjangoFilterBackend` is now completely
|
||||
included by the `django-filter` package.
|
||||
|
||||
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`.
|
||||
|
||||
The existing imports will continue to work but are now pending deprecation.
|
||||

||||

|
||||
|
||||
## 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.

Now that we have our schema `Document`, we can now start to interact with the API:
|

## Authentication
|
||||
|
||||
Typically you'll also want to provide some authentication credentials when
|
||||
instantiating the client.
|
||||
|
||||
#### Token authentication
|
||||
|
||||
The `TokenAuthentication` class can be used to support REST framework's built-in
|
||||
`TokenAuthentication`, as well as OAuth and JWT schemes.
|
||||
|
||||
auth = coreapi.auth.TokenAuthentication(
|
||||
scheme='JWT'
|
||||
token='<token>'
|
||||
)
|
||||
client = coreapi.Client(auth=auth)
|
||||
|
||||
When using TokenAuthentication you'll probably need to implement a login flow
|
||||
using the CoreAPI client.
|
||||
|
||||
A suggested pattern for this would be to initially make an unauthenticated client
|
||||
request to an "obtain token" endpoint
|
||||
|
||||
For example, using the "Django REST framework JWT" package
|
||||
|
||||
client = coreapi.Client()
|
||||
schema = client.get('https://api.example.org/')
|
||||
|
||||
action = ['api-token-auth', 'obtain-token']
|
||||
params = {username: "example", email: "example@example.com"}
|
||||
result = client.action(schema, action, params)
|
||||
|
||||
auth = coreapi.auth.TokenAuthentication(
|
||||
scheme='JWT',
|
||||
token=result['token']
|
||||
)
|
||||
client = coreapi.Client(auth=auth)
|
||||
|
||||
#### Basic authentication
|
||||
|
||||
The `BasicAuthentication` class can be used to support HTTP Basic Authentication.
|
||||
|
||||
auth = coreapi.auth.BasicAuthentication(
|
||||
username='<username>',
|
||||
password='<password>'
|
||||
)
|
||||
client = coreapi.Client(auth=auth)
|
||||
|
||||
## Interacting with the API
|
||||
|
||||
Now that we have a client and have fetched our schema `Document`, we can now
|
||||
start to interact with the API:
|
||||
|
||||
users = client.action(schema, ['users', 'list'])

## Instantiating a client
|
||||
|
||||
In order to interact with the API you'll need a client instance.
|
||||
|
||||
var client = coreapi.Client()
|
||||
|
||||
Header authentication
|
||||
Typically you'll also want to provide some authentication credentials when

var auth = coreapi.auth.HeaderAuthentication({
|
||||
value: 'JWT <token>'
|
||||
})
|
||||
var client = coreapi.Client({auth: auth})
|
||||
#### Session authentication
|
||||
|
||||
Basic authentication
|
||||
The `SessionAuthentication` class allows session cookies to provide the user
|
||||
authentication. You'll want to provide a standard HTML login flow, to allow
|
||||
the user to login, and then instantiate a client using session authentication:
|
||||
|
||||
var auth = coreapi.auth.BasicAuthentication({
|
||||
userName: '<username>',
|
||||
password: '<password>'
|
||||
})
|
||||
var client = coreapi.Client({auth: auth})
|
||||
|
||||
Session authentication
|
||||
|
||||
// https://docs.djangoproject.com/en/dev/ref/csrf/#ajax
|
||||
let auth = coreapi.auth.SessionAuthentication({
|
||||
csrfHeader: 'X-CSRFToken',
|
||||
csrfToken: getCookie('csrftoken')
|
||||
csrfCookieName: 'csrftoken',
|
||||
csrfHeaderName: 'X-CSRFToken'
|
||||
})
|
||||
let client = coreapi.Client({auth: auth})
|
||||
|
||||
## Using the client
|
||||
The authentication scheme will handle including a CSRF header in any outgoing
|
||||
requests for unsafe HTTP methods.

||||
|
||||
Making requests
|
||||
#### Token authentication
|
||||
|
||||
let action = ["users", "list"]
|
||||
client.action(schema, action).then(function(result) {
|
||||
// Return value is in 'result'
|
||||
The `TokenAuthentication` class can be used to support REST framework's built-in
|
||||
`TokenAuthentication`, as well as OAuth and JWT schemes.
|
||||
|
||||
let auth = coreapi.auth.TokenAuthentication({
|
||||
scheme: 'JWT'
|
||||
token: '<token>'
|
||||
})
|
||||
let client = coreapi.Client({auth: auth})
|
||||
|
||||
Including parameters
|
||||
When using TokenAuthentication you'll probably need to implement a login flow
|
||||
using the CoreAPI client.
|
||||
|
||||
let action = ["users", "create"]
|
||||
let params = {username: "example", email: "example@example.com"}
|
||||

||||

|
||||
})
