PageNumber

Utility methods for pagination page and per page that make sure you'll always have a valid number.

Use them your controllers (recommended) or model or anywhere where you process page info.

Usage

PageNumber provides two methods:

• page(n)/__page__(n)
• per_page(n)/__per_page__(n) (defaults to 10)

To use, include or extend the PageNumber module:

require "page_number"

class BaseController
  include PageNumber
end

class SubController < BaseController
  def index
    User.all(:page => page(params[:page]), :per_page => per_page(params[:per_page]))
  end
end

To have better control over how page and per_page work you can define one or more of the following methods:

class BaseController
  include PageNumber

  # These are all optional
  protected

  def page_sizes
    [ 25, 50, 100 ]
  end

  def default_per_page
    20
  end

  def max_page_number
    # who knows!?
  end
