Hi, Adding an index here should have no effect. The reference property stores the key for the referenced value, and retrieving it is a simple get operation - the quickest there is.
I doubt that the timeout is occurring for just one get - if you are operating over a large enough set of data, it is possible this is where the error is occurring, and you should try to reduce the amount of data fetched. With out seeing any code, it's difficult to provide more specific advice on how you might eliminate the timeout message. -Marzia On Fri, Sep 19, 2008 at 11:38 PM, रवींदर ठाकुर (ravinder thakur) < [EMAIL PROTECTED]> wrote: > > hi > > i am developing an application that uses ReferenceProperty heavily. > When i am trying to dereference, i am getting an timeout exception. > > here is my data definition: > > class Triples(db.Model): > subject = > db.ReferenceProperty(Subjects,collection_name="subj_refs") > count = db.IntegerProperty() > > class Subjects(db.Model): > subject = db.StringProperty() > > > and i am taking a triple and accessing it to get the string version of > subject and this is where i am getting an exception.
