If you use the (undocumented) underlying datastore API you will get
datastore objects as lists of dictionary-like objects. It is the
higher level datastore API that converts these objects into Models.
Consequently, using this API is slightly faster as well. For example
from google.appengine.api import datastore
q = datastore.Query("SomeKind", {"name =": "someName"}, None, False,
True, None) # Kind, query, ?, keys_only, compile, cursor
q_results = q.Run()
for result in q_results:
print result.key()
print result['name']
The only mechanism I have found to understand this API is to review
the app engine code. The documentation in the code is pretty
reasonable, but generally no examples.
