Responses for collections in the API are paginated. This means that while a collection may contain tens or hundreds of thousands of objects, in each web request, only a limited number of results are returned for API performance reasons.
When you get back the result for a collection you will see something like:
{'count': 25, 'next': 'http://testserver/api/v1/some_resource?page=2', 'previous': None, 'results': [ ... ] }
To get the next page, simply request the page given by the ‘next’ sequential URL.
To request more items per page, pass the page size query string:
http://<Tower server name>/api/v1/some_resource?page_size=50
The serializer is quite efficient, but you should probably not request page sizes beyond a couple of hundred.
The user interface uses smaller values to avoid the user having to do a lot of scrolling.
