Hi every one,
i need something like populating all the states
when a particular country selected. My exact requirement is, in my
project management tool, when a project is selected all of its
activities should be populated in the next drop down. I think before
rails 3 it can be done using observe_field tag. But how to do that in
rails 3 ( 3.0.10 to be precise) .

As i already mentioned above, i am using 3.0.10 here and the default js library is prototype. But still i am not able make observe_field working. Any ideas?

Is the ajax code there? If so, is its url pointing to the action you expect it to be pointing to? Using Firebug (you can''t do much debugging of ajax without it), when the field changes is the ajax firing and generating the expected post in the console? If you haven''t already, put some logging in the controller action. Is it getting fired? With the expected parameter(s)? Etc...

I am getting this error, when tried to access the form.

i am following this
http://thecloudview.com/dynamic-select-lists-with-ruby-on-rails-and-ajax/
, and doing the same.I doubt prototype in rails3 have no method of
observe_field.

looking at http://apidock.com/rails/v2.3.8/ActionView/Helpers/PrototypeHelper/observe_field i thinkt that method is opt out on 2.3.8 maybe http://railscasts.com/episodes/88-dynamic-select-menus there is a revised version, but it''s for subscriber only Ahmy Yulrizka On Mon, Jan 9, 2012 at 5:02 PM, venkata reddy <venkatareddy.cs-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>wrote:> observe_field-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

looking here solved my problem. http://gregmoreno.ca/rails-3-upgrade-part-4-prototype-helpers-and-javascript/ I think observe_field is a good method to be included. Can''t understand why it''s not there. Thank you all!

observe_field was deprecated as rails 3 is towards being javascript agnostic and requires the developer to have a good grasp of javascript. http://www.simonecarletti.com/blog/2010/06/unobtrusive-javascript-in-rails-3/ On Jan 9, 9:49 pm, venkata reddy <venkatareddy...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> looking here solved my problem. > > http://gregmoreno.ca/rails-3-upgrade-part-4-prototype-helpers-and-jav... > > I think observe_field is a good method to be included.

The same behavior can be duplicated with jQuery. Rails should not include helpers that are tightly bound to any specific JavaScript library. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
