How to add Pagination in Django Project?

Pagination is essential when you have a large set of data and you want to present it to the user in smaller chunks. Django provides built-in support for pagination through its Paginator and Page classes.

Here's a step-by-step guide on how to add pagination in a Django project:

  1. Setup:

    Make sure you have Django installed.

  2. Using Paginator in Views:

    First, you need to use the Paginator class in your views.

    from django.core.paginator import Paginator from django.shortcuts import render def list_view(request): all_items = MyModel.objects.all() # Get all items from the database paginator = Paginator(all_items, 10) # Show 10 items per page page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) return render(request, 'template_name.html', {'page_obj': page_obj})

  3. Updating Templates:

    In your template, you can loop over the items in the current page and also provide navigation for pagination.

    <!-- Display the items --> {% for item in page_obj %} <!-- Display item here --> {% endfor %} <!-- Pagination Controls --> <div class="pagination"> <span class="step-links"> {% if page_obj.has_previous %} <a href="?page=1">&laquo; first</a> <a href="?page={{ page_obj.previous_page_number }}">previous</a> {% endif %} <span class="current"> Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}. </span> {% if page_obj.has_next %} <a href="?page={{ page_obj.next_page_number }}">next</a> <a href="?page={{ page_obj.paginator.num_pages }}">last &raquo;</a> {% endif %} </span> </div>

  4. Styling (Optional):

    You can add some CSS to style the pagination controls to make them more user-friendly. This depends on your specific application and its design requirements.

  5. Using Class-Based Views:

    If you prefer class-based views, Django provides ListView that can handle pagination for you. Just set the paginate_by attribute.

    from django.views.generic import ListView class PaginatedView(ListView): model = MyModel template_name = 'template_name.html' paginate_by = 10

    With this, the items for the current page are available as object_list in the template, and the page object is available as page_obj.

By following these steps, you can easily add pagination to your Django project and improve the user experience by not overwhelming them with too much data at once.
