Question

When persisting domain objects using Grails/GORM I frequently find myself wondering why a save() call fails.

This can easily be solved by adding the logic:

if (!o.save()) {     o.errors.allErrors.each { println it } } 

However, adding this everywhere I do a .save() adds a lot of duplicate code. In the spirit of DRY I’d like to configure Grails/GORM to automatically print any save-errors to the console (stderr). Is that possible? If not, how do I extend GORM to make it possible?

Solution:

Object.metaClass.s = {     def o = delegate.save()     if (!o) {         delegate.errors.allErrors.each {             println it         }     }     o } 

This adds a method called s() that will call save() and print any errors.
