Exclude model properties when syncing (Backbone.js)

Question

Is there a way to exclude certain property from my model when I sync?

For example, I keep in my model information about some view state. Let\'s say I have a picker m

Answer 1

my solution combine all the above. just use white list instead of black one .. this is good rule in general

define

          attrWhiteList:['id','biography','status'],

and then overwrite the save

  save: function(attrs, options) {
    options || (options = {});

 //here is whitelist or all
    if (this.attrWhiteList != null )
          // Filter the data to send to the server
             whitelisted =  _.pick(this.attributes, this.attrWhiteList);
    else  
        whitelisted =this.attributes;
    /* it seems that if you override save you lose some headers and the ajax call changes*/
    // get data
    options.data = JSON.stringify(whitelisted);

    if ((this.get('id') == 0) || (this.get('id') == null)) 
        options.type = "POST"
    else
        options.type = "PUT";


    options.contentType = "application/json";
     //        options.headers =  { 
     //            'Accept': 'application/json',
     //            'Content-Type': 'application/json' 
     //        },

    // Proxy the call to the original save function
   return  Backbone.Model.prototype.save.call(this, attrs, options);
},
