How to create a "like" button

Ive got a like and video model.

On a Video page, Users can click a link ("like") button which will allow them to like a particular video.

Since my like button/image comes in the form of a link and not an actual html form. How should this be implemented? Do I need to specify a ":method => puts" in my link_to tag helper?

What are your thoughts?

AJAX - set the onClick property to point to a function that sends the request to the server.

Ajax is how I am definitely going to implement this with.

However, I need to how to do this without js first.

Is it possible for a link to point to the 'create' method of a controller, passing the necessary values/attributes ?

Or is the only way to do such a thing, through an html form (via post)?

Assuming you have the following models: User, Video, Like. If a Like instance belongs to a video and a user. You could use nested routes in the following format:

resources :video do   resource :like end

Which gives you the following URLS:

/videos/1/like /videos/1/like/1

So then using the proper path and action, you can easily create a link to "like" a video.

link_to("Like!", video_like_path(video), :action => :post)

Then in your Like controller (create method), you simply have to create and save Like instance.

That should be enough to get you going in the right direction.
