Step 4: Data save in the database

First of all, we have already a form which is prepared in previous part. Now we just set save action for this form and  save method contain following code

def save(Contact contact) {

    if (contact == null) {

        transactionStatus.setRollbackOnly()

        notFound()

        return

    }



    if (contact.hasErrors()) {

        transactionStatus.setRollbackOnly()

        respond contact.errors, view:'create'

        return

    }



    contact.save flush:true



    request.withFormat {

        form multipartForm {

            flash.message = message(code: 'default.created.message', args: [message(code: 'contact.label', default: 'Contact'), contact.id])

            redirect contact

        }

        '*' { respond contact, [status: CREATED] }

    }

}

Done
