 Hi all
 For a data model class say
 Person with certain fields,
 how can i access the unique numeric ID field associated with each
 entity in query?
 I use
 persons=db.GqlQuery('SELECT __key__ FROM Person')
 for p in persons:
   self.response.out.write(how to print the ID field here)

self.response.out.write(p.key().id())

You should also replace 'SELECT __key__' with 'SELECT *' in your GQL,
you cannot select individual properties.
