jarredwitt / ampersand-model-validations-mixin Goto Github PK

I am using ampersand-model-validations-mixin in my project.
The validation syntax is

validations: { 'type': { type: function(){ return validateType(this._values.type); }, msg: 'type cannot be blank and it should be unique' },

validateType is a function which checks from database whether it is unique or not.

function validateType(type) {if (_.isEmpty(type)) {return false; } else {var searchData = '{"type" : "' + type + '"}'; dao.searchDocument(process.env.DEVICE_CONNECTOR_TYPE_MODEL, searchData) .then(function(resp) {if (!_.isEmpty(resp)) {return false;}else{ return true;}});}}
But it is not waiting for the result and directly saving it .

Any idea on how to do this ??
