(Quick Reference)
max
Purpose
Ensures a value does not exceed a maximum value.
Examples
age max: new Date()
price max: 999F
Description
Sets the maximum value of a class that implements
java.lang.Comparable. The type of the value must be the same as the property.
Note that constraints are only evaluated once which may be relevant for a constraint that relies on a value like an instance of
java.util.Date.
class User {
... static constraints = {
// this Date object is created when the constraints are evaluated, not
// each time an instance of the User class is validated.
birthDate max: new Date()
}
}This constraint influences
schema generation.
Error Code:
className.propertyName.max.exceeded
