How do I prevent a Grails domain from being updated or deleted?

Question

Once the domain is created and saved, I want to enforce that it doesn't get updated or deleted. What's the simplest and most effective way to achieve this?

Answer 1

One approach is to add two methods, beforeUpdate and beforeDelete, to your Grails domain that both return false. The available GORM event methods are described in the documentation here.

class Example {
    def beforeUpdate() {
        return false;
    }
    def beforeDelete() {
        return false;
    }
}
