Pagination in readRelatedResource

[stfnndrsn]

I can't figure out an way of doing pagination of a related resource.

EloquentController#readRelatedResource

        return $this
            ->reply()
            ->content($model->{$key});

I would gladly help out and update the functionality

Hi! Yes, I need to do some work on the related resources stuff so it is all taken care off out of the box, but haven't got round to that yet.

In the meantime the following should work if you're on the 0.5.x-dev branch:

$paging = app(CloudCreativity\JsonApi\Contracts\Pagination\PaginatorInterface::class);
$page = app(CloudCreativity\LaravelJsonApi\Pagination\Page::class);

/** If the client has requested a page... */
if ($paging->getCurrentPage()) {
    $data = $model->{$key}()->paginate($paging->getPerPage());
} /** Client has not request a page */
else {
    $data = $model->{$key};
}

$page->setData($data);

return $this->reply()->content($page);

Let me know how you get on and obviously I can help more if you're still stuck. I'll probably be able to land proper related resource handling in 0.6 as I'm going to be tagging 0.5 very soon.

Actually, slight correction. The page object will only accept a Laravel paginator in its setData method, so it should be this:

$paging = app(CloudCreativity\JsonApi\Contracts\Pagination\PaginatorInterface::class);
$page = app(CloudCreativity\LaravelJsonApi\Pagination\Page::class);

/** If the client has requested a page... */
if ($paging->getCurrentPage()) {
    $data = $model->{$key}()->paginate($paging->getPerPage());
    $data = $page->setData($data);
} /** Client has not request a page */
else {
    $data = $model->{$key};
}

return $this->reply()->content($data);

On the 1.0 dev branch you can now paginate related resources.
