How to send ajax data to rails 3. jQuery is escaping the string

Question

I'm trying to do this:

$.ajax({
   type: "PUT",
   url: /example,
   data: {_method: "put", "foo_model[bar_attribute]": value_var }
});

And works as expected but I need to construct the part foo_model[bar_attribute]dynamically.

I'm trying with:

var model = "foo_model";
var attribute = "foo_attribute";
var param = model + "[" + attribute + "]";
var dataStr = '{_method: "put",' + param + ': ' + value + '}';

and again:

$.ajax({
   type: "PUT",
   url: /example,
   data: dataStr
});

But it doesn't work, jQuery is escaping quotes and adding curly brackets everywhere around...

Is there any better way to do this? I also tried other ways like making a json object, setting processData to false, as I saw in another post but nothing seems to be working... The request is always transformed and escaped. Also tried unescape but it only works if I write literally:

data: {_method: "put", "foo_model[bar_attribute]": value_var }

Thanks.

You can just use something like this (tested and working)

var model = "foo_model";
var attribute = "foo_attribute";
var param = model + "[" + attribute + "]";
var value = "test";

$.ajax({
  url: "http://fiddle.jshell.net/pu6ME/show/",
  type: "GET",
  data: param + '=' + value
}).done(function() {
   alert("Works!");
});

By using the param + '=' + value workaround you can actually use a dynamic name! I believe it is not possible by using normal key : value syntax, but it doesn't matter in this example.

No need to define datastring.

JSFiddle example (use Control/Cmd + I to view network activity, and you'll see it works)
