Another option would be inheriting from the pagination class, with fewer changes on the view class: from rest_framework.pagination import LimitOffsetPagination class EventNewsItems(APIView, LimitOffsetPagination): def get(self, request, pk, format=None): event = Event.objects.get(pk=pk) news = event.get_news_items().all() results = self.paginate_queryset(news, request, view=self) serializer = NewsItemSerializer(results, many=True) return self.get_paginated_response(serializer.data)
Building on Dan’s answer here is my solution for this problem, with which I was struggling myself until just now. (this JS works on iOS Webkit, no guarantees for android, but please let me know the results) var desiredHeight; var desiredWidth; var bodyID = document.getElementsByTagName(‘body’)[0]; totalHeight = bodyID.offsetHeight; pageCount = Math.floor(totalHeight/desiredHeight) + 1; bodyID.style.padding = … Read more
Building off of Nicola’s answer, you can use the fnDrawCallback() callback and the oSettings object to hide the table pagination after it’s been drawn. With oSettings, you don’t need to know anything about the table settings (records per page, selectors specific to the table, etc.) The following checks to see if the per-page display length … Read more
Lets first understand why offset pagination fails for large data sets with an example. Clients provide two parameters limit for number of results and offset and for page offset. For example, with offset = 40, limit = 20, we can tell the database to return the next 20 items, skipping the first 40. Drawbacks: Using … Read more
Nope. Use: return $this->getEntityManager() ->createQuery(‘…’) ->setMaxResults(5) ->setFirstResult(10) ->getResult();
There is a Page implementation for that: final Page<Something> page = new PageImpl<>(theListOfSomething);
Below code should do it. I am using in my own project and tested for most cases. usage: Pageable pageable = new OffsetBasedPageRequest(offset, limit); return this.dataServices.findAllInclusive(pageable); and the source code: import org.apache.commons.lang3.builder.EqualsBuilder; import org.apache.commons.lang3.builder.HashCodeBuilder; import org.apache.commons.lang3.builder.ToStringBuilder; import org.springframework.data.domain.AbstractPageRequest; import org.springframework.data.domain.Pageable; import org.springframework.data.domain.Sort; import java.io.Serializable; /** * Created by Ergin **/ public class OffsetBasedPageRequest implements Pageable, … Read more
Good question! “How many is too many?” – that, of course, depends on your data size and performance requirements. I, personally, feel uncomfortable when I skip more than 500-1000 records. The actual answer depends on your requirements. Here’s what modern sites do (or, at least, some of them). First, navbar looks like this: 1 2 … Read more
In Laravel 5.3+ use $users->links(‘view.name’) In Laravel 5.0 – 5.2 instead of $users->render() use @include(‘pagination.default’, [‘paginator’ => $users]) views/pagination/default.blade.php @if ($paginator->lastPage() > 1) <ul class=”pagination”> <li class=”{{ ($paginator->currentPage() == 1) ? ‘ disabled’ : ” }}”> <a href=”https://stackoverflow.com/questions/28240777/{{ $paginator->url(1) }}”>Previous</a> </li> @for ($i = 1; $i <= $paginator->lastPage(); $i++) <li class=”{{ ($paginator->currentPage() == $i) ? … Read more
