Trouble with jquery.getJSON prints as undefined or states the function is undefined

This is getting pretty frustrating and i thought this would be alot easier to do, all i'm trying to do is use a rails app i've created as an API, i couldn't seem to get it to work so i created a quick little test app to eliminate any thing that could really be complicated about it, I know very basic java script and my experience doesn't go much further then using Jquery for various effects ect.

I am using the rails-api gem, all I've done in this test is simply ran

Rails g scaffold user name

No views or anything like that has been created, when you navigate to the users path you will see a json array containing the users (currently the only fields would be created, updated, name and id)

Here's my code.

$(document).ready(function(){


$('#new_user').submit(function(e) {
  $.post('/users', $(this).serialize());
  this.reset();
  e.preventDefault();
});

$.getJSON('/users', function(users) {
  $.each(users, function(user) { 
    var output = "<li>" + user.name + "</li>";
    $('#content ul').append(output);
 });
});

});

What the json that .getJson points to looks like

[{"user":{"created_at":"2013-01-23T02:30:42Z","id":1,"name":"test","updated_at":"2013-01-23T02:30:42Z"}},
{"user":{"created_at":"2013-01-23T02:31:49Z","id":2,"name":"test","updated_at":"2013-01-23T02:31:49Z"}}]

Posting works fine, but when when ran, the fields print Undefined, previously if i put user.user.name it would work just fine, obviously that doesn't seem like the best route though.

Is there something I'm missing or is this more complicated then i originally though, I figured all that would really be required to create an API client for my app would be to parse the json like i have here and simply output it to divs.

You need to use user.user.name. $.each iterates over the array, but each has an object with the user key and the name key is inside that.
