This is a very specific question.
All I would like to do is to obtain the URL used by the $resource when it makes calls. For example
var r = $resource('res/:res_id', {res_id: 2});
The reason is that I want access the URL sometimes from an object that is not angular.
I did some googling before coming here. Basically, I need access to the same function that exists here:
https://github.com/angular/angular.js/blob/master/src/ngResource/resource.js
The function is called setUrlParams and it is defined at line 473. If there isn't a public access to this in anyway, I would have to write a function that does the same thing which is not very cool.
