# Pagination

Django provides high-level and low-level ways to help you manage paginated data – that is, data that’s split across several pages, with “Previous/Next” links.

## The `Paginator` class

Under the hood, all methods of pagination use the `Paginator` class. It does all the heavy lifting of actually splitting a `QuerySet` into `Page` objects.

## Example

Give `Paginator` a list of objects, plus the number of items you’d like to have on each page, and it gives you methods for accessing the items for each page:

    >>> from django.core.paginator import Paginator
    >>> objects = ["john", "paul", "george", "ringo"]
    >>> p = Paginator(objects, 2)

    >>> p.count
    4
    >>> p.num_pages
    2
    >>> type(p.page_range)
    <class 'range'>
    >>> p.page_range
    range(1, 3)

    >>> page1 = p.page(1)
    >>> page1
    <Page 1 of 2>
    >>> page1.object_list
    ['john', 'paul']

    >>> page2 = p.page(2)
    >>> page2.object_list
    ['george', 'ringo']
    >>> page2.has_next()
    False
    >>> page2.has_previous()
    True
    >>> page2.has_other_pages()
    True
    >>> page2.next_page_number()
    Traceback (most recent call last):
    ...
    EmptyPage: That page contains no results
    >>> page2.previous_page_number()
    1
    >>> page2.start_index()  # The 1-based index of the first item on this page
    3
    >>> page2.end_index()  # The 1-based index of the last item on this page
    4

    >>> p.page(0)
    Traceback (most recent call last):
    ...
    EmptyPage: That page number is less than 1
    >>> p.page(3)
    Traceback (most recent call last):
    ...
    EmptyPage: That page contains no results

Note

Note that you can give `Paginator` a list/tuple, a Django `QuerySet`, or any other object with a `count()` or `__len__()` method. When determining the number of objects contained in the passed object, `Paginator` will first try calling `count()`, then fallback to using `len()` if the passed object has no `count()` method. This allows objects such as Django’s `QuerySet` to use a more efficient `count()` method when available.

## Paginating a `ListView`

`django.views.generic.list.ListView` provides a builtin way to paginate the displayed list. You can do this by adding a `paginate_by` attribute to your view class, for example:

    from django.views.generic import ListView

    from myapp.models import Contact

    class ContactListView(ListView):
        paginate_by = 2
        model = Contact

This limits the number of objects per page and adds a `paginator` and `page_obj` to the `context`. To allow your users to navigate between pages, add links to the next and previous page, in your template like this:

    {% for contact in page_obj %}
        {# Each "contact" is a Contact model object. #}
        {{ contact.full_name|upper }}<br>
        ...
    {% endfor %}

    <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>

## Using `Paginator` in a view function

Here’s an example using `Paginator` in a view function to paginate a queryset:

    from django.core.paginator import Paginator
    from django.shortcuts import render

    from myapp.models import Contact

    def listing(request):
        contact_list = Contact.objects.all()
        paginator = Paginator(contact_list, 25)  # Show 25 contacts per page.

        page_number = request.GET.get("page")
        page_obj = paginator.get_page(page_number)
        return render(request, "list.html", {"page_obj": page_obj})

In the template `list.html`, you can include navigation between pages in the same way as in the template for the `ListView` above.
