Question

Rails newbie, thanks for help with this hopefully basic JSON type question….

I have a model Books in my app, which belong_to users.

What’d I’d like to learn how to do, is use jQuery to get a JSON object of the books that the user owns. And then use jQuery to list the results out on a div (id=targetdiv).

Where I’m not certain, is is this something Rails 3 does out of the box? Because I see the respond .js, but I think JSON is what is needed by jQuery, right?

Thanks for helping me learn this!

From the Rails point of view, you can do something like this in the relevant controller:

format.js { render :json => @user.books }

Rails knows how to serialize objects to JSON automatically.

From the jQuery point of view, there are probably quite a few methods you could use to convert the returned JSON to HTML and add it to the page. One that’s often recommended is http://github.com/jquery/jquery-tmpl
