Returning URIs as Resource Id's from your Web APIs
|
|
==================================================
|
|
|
|
As a rule, it's probably better practice to return absolute URIs from you web APIs, e.g. "http://example.com/foobar", rather than returning relative URIs, e.g. "/foobar".
|
|
|
|
The advantages of doing so are:
|
|
|
|
* It's more explicit.
|
|
* It leaves less work for your API clients.
|
|
* There's no ambiguity about the meaning of the string when it's found in representations such as JSON that do not have a native URI type.
|
|
* It allows us to easily do things like markup HTML representations with hyperlinks.
|
|
|
|
Django REST framework provides two utility functions to make it simpler to return absolute URIs from your Web API.
|
|
|
|
There's no requirement for you to use them, but if you do then the self-describing API will be able to automatically hyperlink its output for you, which makes browsing the API much easier.

reverse(viewname, request, ...)
|
|
-------------------------------
|
|
|
|
The :py:func:`~reverse.reverse` function has the same behavior as `django.core.urlresolvers.reverse`_, except that it takes a request object and returns a fully qualified URL, using the request to determine the host and port::
|
|
|
|
from djangorestframework.reverse import reverse
|
|
from djangorestframework.views import View
|
|
|
|
class MyView(View):
|
|
def get(self, request):
|
|
context = {
|
|
'url': reverse('year-summary', request, args=[1945])
|
|
}
|
|
|
|
return Response(context)
|
|
|
|
reverse_lazy(viewname, request, ...)
|
|
------------------------------------
|
|
|
|
The :py:func:`~reverse.reverse_lazy` function has the same behavior as `django.core.urlresolvers.reverse_lazy`_, except that it takes a request object and returns a fully qualified URL, using the request to determine the host and port.
