Grails validateable not work for non-persistent domain class

Question

I followed the instruction here: http://www.grails.org/doc/latest/guide/7.%20Validation.html

and added into config.groovy:

grails.valida         


        

Answer 1

You really need to call validate() before - it will trigger validation and change object state. Looking at ValidationGrailsPlugin.addValidationMethods(), I see that hasErrors() is a read-only method.

Your sample worked for me after calling validate(). I tried in grails console (great tool, I highly recommend it!):

Warm w = new Warm('')
w.hasErrors() // 'Result: false'
w.validate()
w.hasErrors() // 'Result: true'

I added @Validateable to Warm class. I believe it makes no difference.

Answer 2

I don't think the validate() and hasErrors() dynamic methods are added in a Unit test. If you move this to an integration test they should be there.
