ios - Adding Objectify index to existing property and existing entity? -

i storing entity using objectify , add index 1 of properties in order run query.

the entity arrives ios client connected via google cloud endpoints. sets property in objective-c class generated servicegenerator.

so have tried adding @index annotation property in eclipse , uploading project again appcfg. however, when inspect datastore in google developers console still says "no indexes serving" , if create new entities , run objectify queries on (now indexed) property still 0 items back.

so exact steps have go through in order add index existing property existing entity defined objectify annotations in eclipse project?

this q&a suggests should straightforward, reason (apparently) not. perhaps complication arises involvement of google cloud endpoints , objective-c client.

update here relevant code snippets, requested:

the property defined follows:

@entity @cache public class someentity {     @id public string someid;     @index string someproperty } 

the ios client sets the property follows (relying on objective-c classes produced servicegenerator):

someentity.someproperty = @"somestring"; 

the server receives , saves entity follows:

@apimethod public addentityresponse addentity(addentityrequest request, httpservletrequest httpservletrequest) throws servletexception {     someentity someentity = request.someentity;     someentity.someid = uuid.randomuuid().tostring();     ofy().save().entity(someentity).now();     // ... } 

when server runs following query receives 0 items back, although entity given property value exists (is e.g. visible in datastore viewer):

ofy().load().type(someentity.class).filter("someproperty", "somestring").list(); 

in order add indexes existing entities have perform these simple steps:

1. annotate properties @index
2. save existing entity

the reason point 2 because annotating entity not enough because in datastore data unaffected. have explicitly re-save existing entity force datastore create index(es) newly annotated properties.

the same applies when removing indexes. must re-save changes take effect.

edit

from code snippet can see query not quite right. invoking query method on object returned type(...) implements loadtype interface neither of 2 interfaces extended [loadtype][1] (namely loadids , query define method! assume haven't created own wrapper code looks standard objectify, i'm not sure how code compiling or not blowing @ runtime.

anyway fix, since looks want filter specified predicate, change query look:

ofy().load().type(someentity.class).filter("someproperty", "somestring").list();
