How deeply does Django in Action cover paginator?

Explains construction, query-parameter handling, boundary checks, page retrieval, and template navigation without deeper implementation internals.

Paginator

As explained in Django in Action

Paginator is a Django utility class that divides an iterable or query result into page-sized subsets and provides access to those pages.

A Paginator divides a large iterable or QuerySet into smaller pages. This avoids information overload for users and prevents one query from returning an unlimited number of objects. section 4.6.3

A typical paginated view follows a short request-to-template flow:

Create a Paginator from the object listing and a per-page limit. section 4.6.3
Read the page number from request.GET, using page 1 when it is absent. section 4.6.3

Paginating musicians

A musicians view orders all musicians by last name, creates Paginator(all_musicians, 2), reads ?page= from the URL, and renders two musicians at a time. The template uses has_previous, has_next, previous_page_number, and next_page_number to show Prev and Next links.
