1. Carter Lathrop 2013-05-30 Navid, Questions or concerns about coding practices or how to do X are not considered bugs and belong in the QA community boards. The Titanium Community Jira is a place to log known bugs or issues with the platform/SDK. Please direct your question to the boards here: https://developer.appcelerator.com/questions/newest Regards, Carter
2. Tony Lukasavage 2013-05-30 [~clathrop] the issue originated from a Q&A question and I asked Navid to add his case here.
3. Navid Ghahramani 2013-05-30 Please Tony add to this issue for support SQLite file defaults while inserting. Refer to: [Defaults on sqlite file](http://developer.appcelerator.com/question/153006/defaults-value-does-not-working)
4. Tim Poulsen 2014-03-12 In my tests, extending the model like this works:

      extendModel : function(Model) {
        _.extend(Model.prototype, {
          validate: function (attrs) {
            for (var key in attrs) {
              var value = attrs[key];
              if (key === "image") {
                if (value.length === 0) {
                  // no image value set
                  attrs[key] = '/images/defaultProduct.png';
                  Model.prototype.save.call(this, attrs);
                }
              }
            }
          }
        });
        // end extend
      
        return Model;
      }
