a Facebook "like" or Twitter "follow" system - in Rails 3

Can anyone point me in the right direction to learn about how I could implement a system similar to facebook's "like" or Twitter's "Follow/Unfollow" system that I could create in Rails?

From what I understand I would need to use Unobtrusive Javascript.

I have a Thing model(has_many :likes) and a Like model (belongs_to :thing)

Any pointers?

You can do ajax call to a function and implement whatever functionality you like inside that function , (in this case "follow" ), you can do it with :

[link_to_function][1]

Incase , you are using rails 3.2.4 and it deprecated, you can use(This is from jeremy's comment. https://gist.github.com/rails/rails/pull/5922#issuecomment-5770442 ):

module LinkToFunctionHelper
  def link_to_function(name, *args, &block)
     html_options = args.extract_options!.symbolize_keys

     function = block_given? ? update_page(&block) : args[0] || ''
     onclick = "#{"#{html_options[:onclick]}; " if html_options[:onclick]}#{function}; return false;"
     href = html_options[:href] || '#'

     content_tag(:a, name, html_options.merge(:href => href, :onclick => onclick))
  end
end
