Hi there,


Coming from PHP, I currently try to learn Rails but got stuck on Ajax as Ruby doesn't know superglobals like $_POST.


Let's say I have an index.html.erb

<div id="box"></div>
<p><%= image_tag("button.png", class: "trigger_button", ajax_path: mymodule_test_path, alt: "Button") %></p>

$('.trigger_button').on('click', function() {
    url: $(this).attr('ajax_path'),
    type: 'POST',
    data: { foo : 'bar' },
    success: function(result) {

What I want to achieve is sending data to an url which processes post['foo'] and renders the result into index.html. In PHP this could look like:

<? $baz = $_POST['foo']; ?>
<p><? echo $baz; ?></p>

But how to solve this in RoR?
