How to fetch a Backbone.js model by something other than the ID?

Question

Backbone.js\'s default, RESTful approach to fetching a model by the ID is easy and straight-forward. However, I can\'t seem to find any examples of fetching a model by a differe

One approach is to override Backbone.sync() method, either for all classes or for just your class. However, presumably your goal is to override fetch for just a single model. One way to do that is to directly call jQuery.ajax(...), and on success, take the response and set that, e.g.

fetchByName: function() {
   var self = this;

    $.ajax({
      url: self.urlRoot+ "?name="+this.get('name'),
      type: 'GET',
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(data) {
          self.set(data);
      }
    });
