Grails dynamic methods

One of the great features of Grails is the dynamic methods that allow you to create complex lookup methods dynamically.

Here's a couple of points though


The InList appender allows you to search by items in a list

Likewise for Criteria.

static findMyAccount(def name, def country, def accountType, def labels) {
(DcmAccount)DcmAccount.createCriteria().get {
eq("name", name
eq("country", country)
eq("accountType", accountType)
'in'("labels", labels)

This is a method on the domain class that I created to lookup accounts based on 4 criteria. Notice the in criteria. It has to be enclosed in quotes since it is a Grails reserved word. It allows you to search for items contained in a list.
