Pagem ↑

Rails gem pagination helper that works off of scopes (named) to facilitate data retrieval and display.

Install ↑

Use the bundler gem (sudo gem install bundler)
Add the following to your Gemfile

  gem "pagem", :git => "git://github.com/mdsol/pagem.git"

Testing ↑

rvm use  ruby-1.9.3-p125
bundle install
bundle exec rspec spec/*

Usage ↑

=== Controller
  In your controller, create an instance of the helper.  Pass your scope and the params hash as arguments.

    @pager = Pagem.new(@study.subjects, params)

  Retrieve the paged scope from the Pagem instance.

    @subjects = @pager.paged_scope

=== View

  In your view, use the paged scope to display the data as you would for any data set.
  Then, render the pagination controls at the bottom.

  <%= @pager %>

  The pagem class can work with remote forms (AJAX) as well.

  <%= @pager.render(:is_remote => true) %>
