## 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:
<form action="/news-items/5" method="POST">
<input type="hidden" name="_method" value="DELETE">
<form action="/" data-method="PUT">
<input name='foo'/>
...
</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:
<form action="/news-items/5" method="PUT">
<input type="hidden" name="_content_type" value="application/json">
<input name="_content" value="{'count': 1}">
</form>
<form action="/">
<input data-override='content-type' value='application/json' type='hidden'/>
<textarea data-override='content'>{}</textarea>
<input type="submit"/>
</form>
`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(',')]
## Doesn't HTML5 support PUT and DELETE forms?
