I think someone has posted this before but the post is not written in
English so I don't understand.
I tested thoroughly in my local machine and there is no problem in
persisting one of my user objects. After I upload it to Google App
Engine, and do the same thing, the following errors occurs:
Uncaught exception from servlet
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found.. <datastore-index kind="Course"
ancestor="true" source="manual">

Unexpected exception from servlet:
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found.. <datastore-index kind="Course"
ancestor="true" source="manual">
<property name="courses_INTEGER_IDX" direction="asc"/>
</datastore-index>
I have "datastore-indexes-auto.xml" in the application in my local
place. I'm not sure if the local datastore and this file has been
uploaded as well( I think not). Is there anyway I can configure the
indexing back to automatic on the appspot? I checked the admin console
and there's no way for me to do this.
Please help me on this. Thanks~
