Django provides a few classes that help you manage paginated data – that is, data that’s split across several pages, with “Previous/Next” links. These classes live in django/core/paginator.py.
For examples, see the Pagination topic guide.
A paginator acts like a sequence of
Page when using
iterating it directly.
Required. A list, tuple,
QuerySet, or other sliceable object with a
__len__() method. For consistent pagination,
QuerySets should be ordered, e.g. with an
order_by() clause or with a default
ordering on the model.
Performance issues paginating large
If you’re using a
QuerySet with a very large number of items,
requesting high page numbers might be slow on some databases, because
OFFSET query needs to count the number of
OFFSET records which takes longer as the page number gets higher.
Required. The maximum number of items to include on a page, not including
orphans (see the
orphans optional argument below).
Optional. Use this when you don’t want to have a last page with very few
items. If the last page would normally have a number of items less than or
orphans, then those items will be added to the previous page
(which becomes the last page) instead of leaving the items on a page by
themselves. For example, with 23 items,
there will be two pages; the first page with 10 items and the second
(and last) page with 13 items.
orphans defaults to zero, which means
pages are never combined and the last page may have one item.
Optional. Whether or not the first page is allowed to be empty. If
object_list is empty, then an
EmptyPage error will
Page object with the given 1-based index, while also
handling out of range and invalid page numbers.
If the page isn’t a number, it returns the first page. If the page number is negative or greater than the number of pages, it returns the last page.
EmptyPage exception only if you specify
Paginator(..., allow_empty_first_page=False) and the
The number of pages to include on each side of the current page number is
determined by the
on_each_side argument which defaults to 3.
The number of pages to include at the beginning and end of page range is
determined by the
on_ends argument which defaults to 2.
For example, with the default values for
if the current page is 10 and there are 50 pages, the page range will be
[1, 2, '…', 7, 8, 9, 10, 11, 12, 13, '…', 49, 50]. This will result in
pages 7, 8, and 9 to the left of and 11, 12, and 13 to the right of the
current page as well as pages 1 and 2 at the start and 49 and 50 at the
InvalidPage if the given page number doesn’t exist.
A translatable string used as a substitute for elided page numbers in the
page range returned by
get_elided_page_range(). Default is
The total number of objects, across all pages.
When determining the number of objects contained in
Paginator will first try calling
object_list has no
count() method, then
fall back to using
len(object_list). This allows objects, such as
QuerySet, to use a more efficient
count() method when
The total number of pages.
A 1-based range iterator of page numbers, e.g. yielding
[1, 2, 3, 4].
A page acts like a sequence of
Page.object_list when using
len() or iterating it directly.
True if there’s a next page.
True if there’s a previous page.
True if there’s a next or previous page.
Returns the next page number. Raises
InvalidPage if next page
Returns the previous page number. Raises
InvalidPage if previous
page doesn’t exist.
Returns the 1-based index of the first object on the page, relative to all
of the objects in the paginator’s list. For example, when paginating a list
of 5 objects with 2 objects per page, the second page’s
start_index() would return
The list of objects on this page.
The 1-based page number for this page.
A base class for exceptions raised when a paginator is passed an invalid page number.
Paginator.page() method raises an exception if the requested page is
invalid (i.e. not an integer) or contains no objects. Generally, it’s enough
to catch the
InvalidPage exception, but if you’d like more granularity,
you can catch either of the following exceptions:
Both of the exceptions are subclasses of
InvalidPage, so you can handle
them both with
