문제

I am developing a Python app using Google App Engine. I want to retrieve property list from an entity along with the key. I am using the code below

recs = db.GqlQuery('select __key__,content from FileHistory')

but I am not able to get the key attribute. Does anybody know how to do it. Do I need to use any keyword to retrieve it.

Thanks,

If you meant to use projection query then you don't need to pass the request for key, it will returned with every query implicitly.

recs = db.GqlQuery('select content from FileHistory')
for rec in recs:
  print rec.key(), rec.content
