<h1 id="format-suffixes">Format suffixes</h1>
|
|
<blockquote>
|
|
<p>Section 6.2.1 does not say that content negotiation should be
|
|
used all the time.</p>
|
|
<p>— Roy Fielding, <a href="http://tech.groups.yahoo.com/group/rest-discuss/message/5857">REST discuss mailing list</a></p>
|
|
</blockquote>
|
|
<p>A common pattern for Web APIs is to use filename extensions on URLs to provide an endpoint for a given media type. For example, 'http://example.com/api/users.json' to serve a JSON representation. </p>
|
|
<p>Adding format-suffix patterns to each individual entry in the URLconf for your API is error-prone and non-DRY, so REST framework provides a shortcut to adding these patterns to your URLConf.</p>
|
|
<h2 id="format_suffix_patterns">format_suffix_patterns</h2>
|
|
<p><strong>Signature</strong>: format_suffix_patterns(urlpatterns, suffix_required=False, allowed=None)</p>
|
|
<p>Returns a URL pattern list which includes format suffix patterns appended to each of the URL patterns provided.</p>
|
|
<p>Arguments:</p>
|
|
<ul>
|
|
<li><strong>urlpatterns</strong>: Required. A URL pattern list.</li>
|
|
<li><strong>suffix_required</strong>: Optional. A boolean indicating if suffixes in the URLs should be optional or mandatory. Defaults to <code>False</code>, meaning that suffixes are optional by default.</li>
|
|
<li><strong>allowed</strong>: Optional. A list or tuple of valid format suffixes. If not provided, a wildcard format suffix pattern will be used. </li>
|
|
</ul>
|
|
<p>Example:</p>
|
|
<pre class="prettyprint lang-py"><code>from rest_framework.urlpatterns import format_suffix_patterns
|
|
|
|
urlpatterns = patterns('blog.views',
|
|
url(r'^/$', 'api_root'),
|
|
url(r'^comments/$', 'comment_list'),
|
|
url(r'^comments/(?P<pk>[0-9]+)/$', 'comment_detail')
|
|
)
|
|
|
|
urlpatterns = format_suffix_patterns(urlpatterns, allowed=['json', 'html'])
|
|
</code></pre>
|
|
<p>When using <code>format_suffix_patterns</code>, you must make sure to add the <code>'format'</code> keyword argument to the corresponding views. For example:</p>
|
|
<pre class="prettyprint lang-py"><code>@api_view(('GET', 'POST'))
|
|
def comment_list(request, format=None):
|
|
# do stuff...
|
|
</code></pre>
|
|
<p>Or with class based views:</p>
|
|
<pre class="prettyprint lang-py"><code>class CommentList(APIView):
|
|
def get(self, request, format=None):
|
|
# do stuff...
|
|
|
|
def post(self, request, format=None):
|
|
# do stuff...
|
|
</code></pre>
|
|
<p>The name of the kwarg used may be modified by using the <code>FORMAT_SUFFIX_KWARG</code> setting.</p>
|
|
<p>Also note that <code>format_suffix_patterns</code> does not support descending into <code>include</code> URL patterns.</p>
|
|
<hr />
|
|
<h2 id="accept-headers-vs-format-suffixes">Accept headers vs. format suffixes</h2>
|
|
<p>There seems to be a view among some of the Web community that filename extensions are not a RESTful pattern, and that <code>HTTP Accept</code> headers should always be used instead.</p>
|
|
<p>It is actually a misconception. For example, take the following quote from Roy Fielding discussing the relative merits of query parameter media-type indicators vs. file extension media-type indicators: </p>
|
|
<p>“That's why I always prefer extensions. Neither choice has anything to do with REST.” — Roy Fielding, <a href="http://tech.groups.yahoo.com/group/rest-discuss/message/14844">REST discuss mailing list</a></p>
|
|
<p>The quote does not mention Accept headers, but it does make it clear that format suffixes should be considered an acceptable pattern.</p>
