Ruby on rails - PUT method on update ajax

Question

Could someone tell me why this PUT method doesn\'t work please.

$.ajax({
        type: \"PUT\",
        dataType: \"script\",
        url: \'/resources/35\',         


        

Answer 1

Rails determines the put request via the parameter _method with the value 'put'.

As not all the browsers support the put method, rails cheats in the form_tag. its putting this output in a PUT form:

So what you have to do is this:

$.ajax({
    type: "POST",
    dataType: "script",
    url: '/resources/35',
    contentType: 'application/json',
    data: JSON.stringify({ resource:{pos_y:45,pos_x:50}, _method:'put' })
}).done(function( msg )
        {
            alert( "Data Saved: " + msg );
        });
