MaxValueValidator

most-data/data-validator~ MaxValueValidator

Validates a value against the maximum value provided

MaxValueValidator is used by DataValidatorListener for validating data objects.

An attribute of a data model may define a min value in validation properties:


     {
        "name": "price",
        "title": "Price",
        "description": "The price of the product.",
        "type": "Number",
        "validation": {
            "maxValue":1000
        }
    }
     

An operation tries to save a data object:


     var obj = {
                "price":1245.50
                "model": "FS2USB42",
                "name": "USB 3.0 Adapter"
            };
     context.model("Product").save(obj).then(function() {
               return done();
           }).catch(function(err) {
               return done(err);
           });
     

Result:


     {
        "code": "EMAXVAL",
        "model": "Product",
        "field": "price",
        "message": "The value should be lower or equal to 1000."
    }
