Hi, I want to know how possible set defaults on Model config definition that use pre sqlite file without set to sqlite file I set to model config like this but it's not working this is my config:

    config: {
        "adapter": {
            "type": "sql",
            "collection_name": "product",
            "db_file": "/db.sqlite",
            "idAttribute": "id",
            "remoteBackup": false
        },
        "defaults": {
            "image": "/images/defaultProduct.png"
        }
    },
    extendModel: function (Model) {
        _.extend(Model.prototype, {
 
        });
        // end extend
 
        return Model;
    },
 
    extendCollection: function (Collection) {
        _.extend(Collection.prototype, {
 
        });
        // end extend
 
        return Collection;

[~clathrop] the issue originated from a Q&A question and I asked Navid to add his case here.

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)

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;
   }

Closing as won't fix because there's a workable method to accomplish the desired outcome without making Alloy changes.
