Myna. ValidationResult

Stores the results of one or more validation operations

Detail

A validation result starts out representing a successful operation.  Calls to addError will change success to false, and store the error.  Multiple ValidationResult objects can be merged via the merge function, allowing several operations to return a single result object.  ValidationResult is primarily used to return information to the browser regarding the status of an AJAX call, and ValidationResult.toJson() will return an appropriate JSON string for an Ext form submit action.  ValidationResult objects are also returned by Myna.DataManager.beanTemplate “set” functions

Example

Myna.DataManager.beanTemplate.setFields=function(fields){
    var bean = this;
    var result = new Myna.ValidationResult();
        fields.getKeys().forEach(function(name){
            if (bean.columnNames.indexOf(name) != -1){
                result.merge(bean["set_"+name](fields[name]));
            }
        })

    return result;
}

bean.baseBean["set_"+fname] = function (newval){
    var result = new Myna.ValidationResult();
    if (typeof newval === "undefined"){
        result.addError("argument 'newval' required for set" +fname +".",fname);
        return result;
    }
    if (newval != this.data[arguments.callee.fieldName]){
        result.merge(this.saveField(arguments.callee.fieldName,newval));
        this.data[arguments.callee.fieldName] = newval;
    }
    return result;
}
