Index transient fields

[jordim]

Is that possible?

I am also interested in being able to store transient domain object fields in Elastic Search. My initial attempts were not successful - the fields are not added to the index. Is there a limitation on adding transitive fields to the index?

Here is an example how i used transient props in grails-elasticsearch plugin:
Domain class:
static searchable = {
root false
compositeName index: 'not_analyzed'
transientsProp = ['compositeName']
except = ['userRoleList','userProfile','creationSource']
}

public String getCompositeName(){
return this.firstname + " " + this.lastname
}
static transients = ['compositeName']

Added
private Object transientsProp;
to SearchableDomainClassMapper.java

I am using the searchable closure, so i adapted the method buildMappingFromOnlyExcept
Added:
Set propTransients = convertToSet(transientsProp);

if (!propTransients.isEmpty()) {
mappableProperties.addAll(propTransients);
}

In DeepDomainClassMarshaller.groovy, i changed domainClass.getPersistantProperties to
for (GrailsDomainClassProperty prop in domainClass.properties) {

I've tried cthoma's fix and it works. Thanks for sharing here!

There's a problem, if the transient property is trying to access id of current object, it's throwing an AssertionFailure in buildJSON() method in JSONDomainFactory.
@thch0014 - any ideas if you might have faced the same ?

UPDATE:
Resolved it by wrapping innards of transient getter method, inside a withNewSession{...}
