Class Ramaze::Helper::Paginate::Paginator

Public Instance methods

Returns a new Paginator instance.

Note that the pagination relies on being inside a Ramaze request to gain necessary metadata about the page it resides on, you cannot use it outside of Ramaze yet.

The examples below are meant to be used within your controller or view.

Usage with Array:

    data = (1..100).to_a
    @pager = paginate(data, :limit => 30, :page => 2)
    @pager.navigation
    @pager.each{|e| puts(e) }

Usage with Sequel:

    data = Article.filter(:public => true)
    @pager = paginate(data, :limit => 5)
    @pager.navigation
    @pager.each{|e| puts(e)

Note that you must first extend Sequel with the pagination extension"

    Sequel.extension :pagination

@param [Sequel::Dataset|Array] dataset May be a Sequel dataset or an

 Array

@param [Hash] options A hash containing custom options that takes

 precedence to ``trait[:paginate].

@option options [Fixnum] :limit The number of elements used when you

 call #each on the paginator

 request, this is helpful if you want to use two or more independent
 paginations on the same page.
