The following seems to work:
This in the view:
var up = function () {
this.attr({opacity: 1.0});
var locx_val = this.attr("x");
$.ajax({
type: "POST",
url: "{{ =URL('new_post') }}",
data: {locx:locx_val}
})
results in the db:
<Storage {'locx': '348'}>
Which is the x coordinate of the Raphael element at the end (up) of the
drag.
The data is indeed added to the url!
Thank you Massimo.
