# you'll need activerecord to use ActiveRecordPager
module Pagify
# active_record paginator was provided for convenience,
# it wraps Paginator for you, and you can just pass the model class to it.
# you don't have to care about the fetcher and counter.
# additionally, you can pass other options to rails paginator,
# they would be used in find options. e.g.,
# ActiveRecordPaginator.new Model, :order => 'created_at DESC'
# would invoke Model.find :all, :offset => ?, :limit => ?, order => 'created_at DESC'
class ActiveRecordPager < BasicPager
include PageAcceptStringOrBlank
# the model class that you passed in this paginator
attr_reader :model
def initialize model_class, opts = {}
@model = model_class
query_opts = reject_pager_opts(opts)
super(opts.merge(
:fetcher => lambda{ |offset, per_page|
model.find(:all, query_opts.merge(:offset => offset, :limit => per_page))
},
:counter => lambda{
model.count(query_opts)
}))
end
