Unobtrusive ext-core with Rails 3
What version of Ext core I should use?
You can use ext core v3.1.0 or extjs v4.0-pr1.
ext-ujs supports Firefox/Chrome/Opera. IE9 RC is supported only with extjs v4.0-pr1.
Install testing requirements?
$ gem install bundler $ bundle install
How do I run specs?
$ bundle exec ruby spec/server.rb
Visit localhost:4567 and all the specs should pass. If you want to change any settings then change the settings at the top of spec/public/spec/settings.js .
