will_paginate on AJAX

Do you want will_paginate with AJAX functionality ?

  1. Remove will_paginate plugin if you have it (/vendor/plugins/) /or backup it.
  2. in command line: gem sources -a
  3. in command line: gem install mislav-will_paginate
Now in config/environment.rb put after Initializer do |config|

require 'will_paginate'
Next step, create new helper: remote_link_renderer.rb .. and copy&paste inside:

class RemoteLinkRenderer < WillPaginate::LinkRenderer
def prepare(collection, options, template)
@remote = options.delete(:remote) || {}
def page_link(page, text, attributes = {})
@template.link_to_remote(text, {:url => url_for(page), :method => :get}.merge(@remote))
#replace :method => :post if you need POST action

Now, to ajaxize put:
<%= will_paginate :collection, :renderer => "RemoteLinkRenderer",:remote => {:with => "something_you_want", :update => "dom_id_element"} %>

And you are happy-ajax-paginator !
<%= will_paginate @events, :renderer => "RemoteLinkRenderer",:remote => {, :update => "events_container", :loading => visual_effect(:appear, "loader"),:complete =>visual_effect(:fade,"loader" ) } %>
will call /events?page=x with AJAX request..
in my EventController:

respond_to do |format|
format.html { }
format.js { render :partial => "events" }
format.xml { render :xml => @events.to_xml }

Thats all !!

acts_as_taggable_on_steroids + Globalize

Okay, situation is:

Parties involved: Rails 2.0.2, Globalize plugin, acts_as_taggable_on_steroids, ME.
(clickables) :)

Having model Event that translates :name, :body, :description with Globalize plugin.
Also Event are acts_as_taggable with acts_at_taggable_on_steroids ...

Ok for now, model works well, translated well, adding/removing/editing tags as well !

The problem is raise when we trying to @tags = Event.tag_cloud
we got :select option not allowed on translatable models (DISTINCT * FROM events .... !! THAT IS BADD !!!

Open /ventor/plugin/acts_as_tabbable_on_steroids/lib/acts_as_taggable.rb

LINE: 66
def find_tagged_with(*args)
options = find_options_for_find_tagged_with(*args)
options.blank? ? [] : find(:all, options)


def find_tagged_with(*args)
options = find_options_for_find_tagged_with(*args)
options.blank? ? [] : untranslated_find(:all, options)

Restart server and you're done !

p.s. More info about great acts_as_taggable_on_steroid plugin is here.
