  console.log("save>>");
    var form = $("#formValidate");
    form.validate({
        rules: {
            username: {
                required: true,
                minlength: 5
            },

        },
        //For custom messages
        messages: {
            username:{
                required: "Enter a username",
                minlength: "Enter at least 5 characters"
            },
            //curl: "Enter your website",
        },
        errorElement : 'div',
        errorPlacement: function(error, element) {
          var placement = $(element).data('error');
          if (placement) {
            $(placement).append(error)
          } else {
            error.insertAfter(element);
          }
        }
     });
 },
 didInsertElement: function(){
    let self = this;
    self.validate();
 },

actions:{
    save: function(){
          let self = this;
         /* var form = $("#formValidate");
          var isValid = form.validate();*/
          $(document).ajaxError(function(event, jqxhr) {
            var jsonResponse = JSON.parse(jqxhr.responseText);
            Materialize.toast(jsonResponse.statusMessage, 3000);  
          });  
            self.get('model').save().then(function(response){                  
            Materialize.toast(response.get("statusMessage"), 3000);  
          });      
        }
}
