Question

Iam upgrading grails2 project to grails3. i've some logic in beforeUpdate and afterInsert but as grails3 removed before and after interceptors How can i use that logic in grails3?

Answer 1

You can simply define a method within domain class like:

def beforeInsert(){
//do some stuff
}

Method name is important here, here is complete list of supported events/methods:

beforeInsert
beforeUpdate
beforeDelete
beforeValidate
afterInsert
afterUpdate
afterDelete
onLoad

Answer 2

Think of the 'beforeInsert' and 'afterInsert' like an interceptor/filter; they are merely functions that will be triggered prior/after a insert of the data for the domain object.

It works very similar to 'before/after' for Interceptor for controllers. :)
