Using only Pagerfanta helpers with Symfony 2 and Twig - symfony

Question

I have an application that consumes a webservice. My app send request to webservice like this:
Request example:
https://mywebservice.com/interesting-route/?page=4&limit=30
So I receive just a slice of result, not the complete array, else I could use ArrayAdapter to paginate in my controller. I wanna use just the twig extension to generate DOM elements in my views.
Response example:
{
results:
[
{
title: 'Nice title',
body: 'Nice body'
},
...,
{
title: 'Nice title',
body: 'Nice body'
},
],
total: 1350,
limit: 30
]
What's the way, maybe using FixedAdapter?
Thanks

As you say, the FixedAdapter should do what you need here. Here's some sample controller code you could adapt:
public function someAction(Request $request)
{
$page = 1;
if ($request->get('page') !== null) {
$page = $request->get('page');
}
$totalResults = // call your webservice to get a total
$limit = 30;
$slice = $this->callMyWebserviceInterestingRoute($page, $limit);
$adapter = new FixedAdapter($totalResults, $slice);
$pagerfanta = new Pagerfanta($adapter);
$pagerfanta->setMaxPerPage($limit);
$pagerfanta->setCurrentPage($page);
return $this->render('default/pages.html.twig', [
'my_pager' => $pagerfanta,
]);
}
Hope this helps.
