How to use in_place_form_edit in Rails 2.0

(1)first u need to install the plugin from svn
>ruby script/plugin source http://svn.rubyonrails.org/rails/plugins/


>ruby script/plugin install in_place_editing




(2)Because it is unsupported the in_place_edit plugin has not kept up with changes to rails. This has resulted in the plugin not working with Rails 2+ because of the Cross-Site-Request-Forgery (CSRF) security modifications that include a authenticity token with every non-GET request.




(3)View the patch located http://dev.rubyonrails.org/attachment/ticket/10055/in_place_editing_should_work_with_csrf_and_rjs.patch


and by hand change the code in yourapp/vendor/plugin/in_place/editing/test/in_place_editing_test.rb. The red lines are deleted/replaced and the green are the new lines that are added.




(4)In the controller

class TaskController < ApplicationController
in_place_edit_with_validation_for :task, :title




(5)In views do like this for the field u want to edit

<%@task=task %><%= in_place_editor_field :task, :title %>



(6)Then start ur server and you will see really how simple it is



(7)so u think it is finished no way there is a bug in this if u just press OK with empty field u will get u know that ur really in trouble.So to make ur day happy go through this url to make validations
