Ajax based drag drop and sortable tree for Rails

My friend sur wrote and shares his code for Ajax based drag drop sortable tree for rails. He is also trying to pluginize this, and soon it will be publicly available. Find more detail here.

Uploading files using AJAX

There is no way to upload files using AJAX. How Gmail does it then? Well, the answer is using <iframe>. Here is a post that describe this technique in detail. Infact we are using this technique from months, obviously inspired by Gmail. ;-)

update: Technically speaking, it’s not Ajax. Just an iframe hack. You are absolutly right Pratik.

Ruby On Rails India

As far as I know there are very few people working on RubyOnRails in India. Vinayak solutions Pvt. Ltd. is doing great in this field. Recently Manik Juneja (Director) attended the Rails conf. Landon and last week traveled Colombo to train a team of web programmers on Ruby on Rails.

Lib file state_select.rb

If you are not interested in installing a plugin just for one method(state_select) then You can put state_select.rb file in you rails lib directory. And include state_select.rb file in your controller where ever you want to use state_select method.

The url for state_select.rb is http://opensvn.csie.org/state_select/trunk/lib/state_select.rb
Feedback please….

Plugin: state_select, generate drop down selection box for states

I have wrote my first plugin(state_select). This plugin allows to create drop down list for states, same as country_select method in rails. I know this is not a big deal…

Curently it can generate state list for India, US, Canada, Australia and Spain(default is US).

Usage:

• state_select(object, method, country='US', options = {}, html_options = {})

Return select and option tags for the given object and method, using state_options_for_select to generate the list of option tags.

• state_options_for_select(selected = nil, country = 'US')

Returns a string of option tags for states in a country. Supply a state name as selected to have it marked as the selected option tag.

NOTE: Only the option tags are returned, you have to wrap this call in a regular HTML select tag.

The svn repository can be found at http://opensvn.csie.org/state_select/trunk/

Install plugin by

script/plugin install http://opensvn.csie.org/state_select/trunk/
