==========
|
|
||||||
|
|
||||||
To install:
|
|
||||||
|
|
||||||
script/plugin install svn://errtheblog.com/svn/plugins/classic_pagination
|
|
||||||
|
|
||||||
This code was extracted from Rails trunk after the release 1.2.3.
|
|
||||||
WARNING: this code is dead. It is unmaintained, untested and full of cruft.
|
|
||||||
|
|
||||||
There is a much better pagination plugin called will_paginate.
|
|
||||||
Install it like this and glance through the README:
|
|
||||||
|
|
||||||
script/plugin install svn://errtheblog.com/svn/plugins/will_paginate
|
|
||||||
|
|
||||||
It doesn't have the same API, but is in fact much nicer. You can
|
|
||||||
have both plugins installed until you change your controller/view code that
|
|
||||||
handles pagination. Then, simply uninstall classic_pagination.

# === Action Pack pagination for Active Record collections
|
|
||||||
#
|
|
||||||
# The Pagination module aids in the process of paging large collections of
|
|
||||||
# Active Record objects. It offers macro-style automatic fetching of your
|
|
||||||
# model for multiple views, or explicit fetching for single actions. And if
|
|
||||||
# the magic isn't flexible enough for your needs, you can create your own
|
|
||||||
# paginators with a minimal amount of code.
|
|
||||||
#
|
|
||||||
# The Pagination module can handle as much or as little as you wish. In the
|
|
||||||
# controller, have it automatically query your model for pagination; or,
|
|
||||||
# if you prefer, create Paginator objects yourself.
|
|
||||||
#
|
|
||||||
# Pagination is included automatically for all controllers.
|
|
||||||
#
|
|
||||||
# For help rendering pagination links, see
|
|
||||||
# ActionView::Helpers::PaginationHelper.
|
|
||||||
#
|
|
||||||
# ==== Automatic pagination for every action in a controller

#
|
|
||||||
# # ...
|
|
||||||
# end
|
|
||||||
#
|
|
||||||
# Each action in this controller now has access to a <tt>@people</tt>
|
|
||||||
# instance variable, which is an ordered collection of model objects for the
|
|
||||||
# current page (at most 20, sorted by last name and first name), and a
|
|
||||||
# <tt>@person_pages</tt> Paginator instance. The current page is determined
|
|
||||||
# by the <tt>params[:page]</tt> variable.
