MinValueValidator

MinValueValidator

Validates a value against the minimum value provided

MinValueValidator is used by DataValidatorListener for validating data objects.

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


 {
    "name": "price",
    "title": "Price",
    "description": "The price of the product.",
    "type": "Number",
    "validation": {
        "minValue":5
    }
}
 

An operation tries to save a data object:


 var obj = {
                "price":2.5
                "model": "FS2USB42",
                "name": "USB 3.0 Adapter"
            };
 context.model("Product").save(obj).then(function() {
               return done();
           }).catch(function(err) {
               return done(err);
           });
 

and the result is:


 {
    "code": "EMINVAL",
    "model": "Product",
    "field": "price",
    "message": "The value should be greater than or equal to 5."
}
