+## Query parameter formats
+
+An alternative to the format suffixes is to include the requested format in a query parameter. REST framework provides this option by default, and it is used in the browsable API to switch between differing available representations.
+
+To select a representation using its short format, use the `format` query parameter. For example: `http://example.com/organizations/?format=csv`.
+
+The name of this query parameter can be modified using the `URL_FORMAT_OVERRIDE` setting. Set the value to `None` to disable this behavior.

## Accept headers vs. format suffixes
There seems to be a view among some of the Web community that filename extensions are not a RESTful pattern, and that `HTTP Accept` headers should always be used instead.

> — [RESTful Web Services][cite], Leonard Richardson & Sam Ruby.
+In order to allow the browsable API to function, there are a couple of browser enhancements that REST framework needs to provide.
+
+As of version 3.3.0 onwards these are enabled with javascript, using the [ajax-form][ajax-form] library.
+
## Browser based PUT, DELETE, etc...
-REST framework supports browser-based `PUT`, `DELETE` and other methods, by
-overloading `POST` requests using a hidden form field.
+The [AJAX form library][ajax-form] supports browser-based `PUT`, `DELETE` and other methods on HTML forms.
-Note that this is the same strategy as is used in [Ruby on Rails][rails].
+After including the library, use the `data-method` attribute on the form, like so:
-For example, given the following form:
-
-
-`request.method` would return `"DELETE"`.
-
-## HTTP header based method overriding
-
-REST framework also supports method overriding via the semi-standard `X-HTTP-Method-Override` header. This can be useful if you are working with non-form content such as JSON and are working with an older web server and/or hosting provider that doesn't recognise particular HTTP methods such as `PATCH`. For example [Amazon Web Services ELB][aws_elb].
-
-To use it, make a `POST` request, setting the `X-HTTP-Method-Override` header.
-
-For example, making a `PATCH` request via `POST` in jQuery:
-
- $.ajax({
- url: '/myresource/',
- method: 'POST',
- headers: {'X-HTTP-Method-Override': 'PATCH'},
- ...
- });
+Note that prior to 3.3.0, this support was server-side rather than javascript based. The method overloading style (as used in [Ruby on Rails][rails]) is no longer supported due to subtle issues that it introduces in request parsing.
## Browser based submission of non-form content
-Browser-based submission of content types other than form are supported by
-using form fields named `_content` and `_content_type`:
+Browser-based submission of content types such as JSON are supported by the [AJAX form library][ajax-form], using form fields with `data-override='content-type'` and `data-override='content'` attributes.
-For example, given the following form:
+For example:
-
+
-`request.content_type` would return `"application/json"`, and
-`request.stream` would return `"{'count': 1}"`
-
-## URL based accept headers
-
-REST framework can take `?accept=application/json` style URL parameters,
-which allow the `Accept` header to be overridden.
-
-This can be useful for testing the API from a web browser, where you don't
-have any control over what is sent in the `Accept` header.
+Note that prior to 3.3.0, this support was server-side rather than javascript based.
## URL based format suffixes
@@ -63,8 +41,37 @@ REST framework can take `?format=json` style URL parameters, which can be a
useful shortcut for determining which content type should be returned from
the view.
-This is a more concise than using the `accept` override, but it also gives
-you less control. (For example you can't specify any media type parameters)
+This behavior is controlled using the `URL_FORMAT_OVERRIDE` setting.
+
+## HTTP header based method overriding
+
+Prior to version 3.3.0 the semi extension header `X-HTTP-Method-Override` was supported for overriding the request method. This behavior is no longer in core, but can be adding if needed using middleware.
+
+For example:
+
+ METHOD_OVERRIDE_HEADER = 'HTTP_X_HTTP_METHOD_OVERRIDE'
+
+ class MethodOverrideMiddleware(object):
+ def process_view(self, request, callback, callback_args, callback_kwargs):
+ if request.method != 'POST':
+ return
+ if METHOD_OVERRIDE_HEADER not in request.META:
+ return
+ request.method = request.META[METHOD_OVERRIDE_HEADER]
+
+## URL based accept headers
+
+Until version 3.3.0 REST framework included built-in support for `?accept=application/json` style URL parameters, which would allow the `Accept` header to be overridden.
+
+Since the introduction of the content negotiation API this behavior is no longer included in core, but may be added using a custom content negotiation class, if needed.
+
+For example:
+
+ class AcceptQueryParamOverride()
+ def get_accept_list(self, request):
+ header = request.META.get('HTTP_ACCEPT', '*/*')
+ header = request.query_params.get('_accept', header)
+ return [token.strip() for token in header.split(',')]
