"""

This example demonstrates displaying search results using pagination.
|
||
|
|
|
||
|
|
Named capture groups (?P<name>...) will be passed along as additional keyword
|
||
|
|
arguments to the wrapped function. You can apply two routes to the same view in
|
||
|
|
order to make the page number optional in the URL.
|
||
|
|
|
||
|
|
Try to think outside of the box when you design your UX. Will users need to
|
||
|
|
navigate forward/backward through the results, or only forward? Should the
|
||
|
|
number or results returned per-page be controllable?
