How to get value of a domain constraint in Grails?

I have a text field whose length I would like to limit at the maxSize constraint of one of my domain classes.

So if I have a class foo:

class Foo {
    String bar

    static constraints = {
        bar(maxSize: 100)
    }
}

I would like to get that value of 100 for the property bar. Is this possible?

Solution

  • You should be able to do:

    def maxBarSize = Foo.constraints.bar.getAppliedConstraint( 'maxSize' ).maxSize
