class::dbi::pager
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.
