The PaginationScope library is a pagination library of the NamedScope era.

The difference to the last version is only a small bug fix. So you can keep using it if you don't mind.

That's all. But I shall use this opportunity to write some document for the helper method of the library.

SYNOPSIS:

   1  paginate <scope>[, <options>]

The scope is a pagination scope object. The options is a hash including several parameters as follows.

• :newer The label string for the link to a newer page.
• :older The label string for the link to an older page.
• :left The number of pages which appears on the left side.
• :right The number of pages which appears on the right side.
• :window The width of pages which surrounds the current page.

I made a new pagination library for the NamedScope era. You can use will_paginate for ordinary case. It must be better than the young PaginationScope library. But if you want to paginate with complicated chained named_scopes, this is suitable.

Usage

At first, include the module into your model class.

   1  class Post
   2    include PaginationScope

By this, the scope named "paginate" is made.

And then, in the controller of which you want to use pagination, you can get the scope for pagination like this.

   1  class PostsController < ApplicationController
   2    def index
   3      @posts = Post.not_deleted.paginate(params[:page], 10)

Finally, the pagination links are generated by calling the view helper, like this.

   1  <%= paginate @posts %>

Have fun!
