Maybe you should not use fetch() or a gql() with LIMIT and OFFSET but
use the Query object and GqlQuery object as iterators. The filter()

If you use a file in your application code it CAN NOT be put in a static folder.
You have to make a separate folder for the templates and not set it to static.
Static files are NOT accessible for code.

What it means is that if you want to update multiple objects in a

You have to write your own Template filters.

The decision to rerun a task is done based on the HTTP response code.
There is always a response code, even when the connection is lost.
When the code is 200 the task is considered complete and will not be rerun.

If it was possible to get the source code through remote_api or
appcfg.py-hacking it would be possible for the client who only has the

With the remote_api you can write a small script that deletes all the
items off a certain class.
Have a look at the article about the remote_api.
The MyModelDeleter class is all you need, and some of CPU time.

If you don't know the key of the object, page over all keys of that
object type and
probably not, from the Python 2.5 manual
--
hasattr( object, name)
The arguments are an object and a string. The result is True if the
string is the name of one of the object's attributes, False if not.
(This is implemented by calling getattr(object, name) and seeing
whether it r
The reference property contains the Key of the object referred to.
You can get this key with
key = MyModel.assigned.get_value_for_datastore(obj2)
obj1 = db.get(key)
if obj is None:
pass # invalid reference
Or you can put a "try: except" around the code and as such find out if
the object exis

There is a small bug in the SDK version of the DataViewer
in the file google_appengine/google/appengine/ext/admin/__init__.py
in class DatastoreQueryHandler(DatastoreRequestHandler): the get()
handler around line 665 (SDK 1.2.3).
The page_start variable can be a float, the range() call a few line
All GAE servers have GMT/UTC as there current time.
The times across different servers may very a few seconds because they
are distributed.

Have a look at this article
http://code.google.com/appengine/articles/images.html
It shows how to do it with images but other file types stored in GAE
objects can be served the same way.
Did you succeed to store the file in a GAE object?

Every object can have a ReferenceProperty that points to One (1) object.
There is no limit to the number of references to an object.

Your query will probably fetch more then 25 Action objects. Fetching
all those Keys is fast. Fetching all the complete objects is slow, you
fetch a lot more then you need.
If you iterate over the GQL query, no fetch, that requests full Action
objects (SELECT * FROM ACTION...), the objects wil
Every "a.project" statement results in a db.get() operation.
Try to batch get() the project_key cache misses, and then set_multi()
these in memcache.
Put/Copy the project.active and project.deleted booleans in the Action object.
Then you can use them in the query and just fetch 25 Action objects
If it is about response time I think the normal-fetch(3) is faster.
Only one call to the datastore, objects are fetched and converted to
python-objects in parallel.
If you also want to optimize the CPU-ms it depends on the size of the objects.
Writing a test is the only way to know for your type
No difference, if both objects have the same number and type of attributes.
The index scan time is independent of the number of entries in the index.
