custom simple constraint grails

Question

I would like to create a custom simple constraint (like display and editable) which I can use within my Domain class. Is it possible to extend ConstrainedProperty class?

Answer 1

To create your own constraint:

• extend org.codehaus.groovy.grails.validation.AbstractConstraint
• register the class as a constraint by calling org.codehaus.groovy.grails.validation.ConstrainedProperty.registerNewConstraint

Take a look at the grails implementation of the size constraint for an example.
