Class::DBI::Pager(3pm)					User Contributed Perl Documentation				    Class::DBI::Pager(3pm)

NAME
Class::DBI::Pager - Pager utility for Class::DBI SYNOPSIS
package CD; use base qw(Class::DBI); __PACKAGE__->set_db(...); use Class::DBI::Pager; # just use it # then, in client code! package main; use CD; my $pager = CD->pager(20, 1); # ($items_per_page, $current_page) my @disks = $pager->retrieve_all; DESCRIPTION
Class::DBI::Pager is a plugin for Class::DBI, which glues Data::Page with Class::DBI. This module reduces your work a lot, for example when you have to do something like: * retrieve objects from a database * display objects with 20 items per page In addition, your work will be reduced more, when you use Template-Toolkit as your templating engine. See "EXAMPLE" for details. EXAMPLE
# Controller: (MVC's C) my $query = CGI->new; my $template = Template->new; my $pager = Film->pager(20, $query->param('page') || 1); my $movies = $pager->retrieve_all; $template->process($input, { movies => $movies, pager => $pager, }); # View: (MVC's V) Matched [% pager.total_entries %] items. [% WHILE (movie = movies.next) %] Title: [% movie.title | html %] [% END %] ### navigation like: [1] [2] [3] [% FOREACH num = [pager.first_page .. pager.last_page] %] [% IF num == pager.current_page %][[% num %]] [% ELSE %]<a href="display?page=[% num %]">[[% num %]]</a>[% END %] [% END %] ### navigation like: prev 20 | next 20 [% IF pager.previous_page %] <a href="display?page=[% pager.previous_page %]"> prev [% pager.entries_per_page %]</a> | [% END %] [% IF pager.next_page %] <a href="display?page=[% pager.next_page %]"> next [% pager.entries_per_page %]</a> [% END %] NOTE
/ TODO This modules internally retrieves itertors, then creates "Data::Page" object for paging utility. Using SQL clauses "LIMIT" and/or "OFFSET" with "DBIx::Pager" might be more memory efficient. AUTHOR
