mapping multiple tables for one class

2013-08-01T14:24:31+00:00

I'm doing something to finish the horizontal shard job.
The examle is sharding to multiple database . And i just do it for
multipls tables in one database.

there is many tables just like  msg_00,msg_01..... msg_99
defind  the class like  Msg()  map the tables .

===============================
m = Msg
number = int(uid)%100
tablename = 'msg_%02d'%(number)
m.__uuid__ = uid
m.__table__.name = tablename
===============================
now  "m" mapping the table msg_xx .
It works in the select sql.
but fail in the session.add(newmessage) because the sqlalchemy has cache
connection .  event one table is  Table(msg_00) and another is Table
(msg_01)

So, i edit the memo key .   then there is diff  insert object .

------------------
It's simple change and useful. It‘s safe for the old version .
sorry for my poor english.

- Fixed bug in common table expression system where if the CTE were

2013-07-31T22:42:58+00:00

used only as an ``alias()`` construct, it would not render using the
WITH keyword.  Also in 0.8.3, 0.7.11.
[ticket:2783]

- this collection can be None on cleanup, so check for that

- fix issue in join rewriting whereby we need to ensure the .key and .name

2013-07-27T21:05:01+00:00

are transferred correctly for when .key is present; tests have been enhanced
to test this condition for render, result map construction, statement
execution.  [ticket:2790]

- The C extensions are ported to Python 3 and will build under

any supported CPython 2 or 3 environment. [ticket:2161]

- add event.contains() function to the event package, returns True

if the given target/event/fn is set up to listen.
- repair mutable package which is doing some conditional event listening

- Removal of event listeners is now implemented. The feature is

2013-07-26T18:21:58+00:00

provided via the :func:`.event.remove` function.
[ticket:2268]
- reorganization of event.py module into a package; with the addition of the
docstring work as well as the new registry for removal, there's a lot more code now.
the package separates concerns and provides a top-level doc for each subsection
of functionality
- the remove feature works by providing the EventKey object which associates
the user-provided arguments to listen() with a global, weak-referencing registry.
This registry stores a collection of _ListenerCollection and _DispatchDescriptor
objects associated with each set of arguments, as well as the wrapped function
which was applied to that collection.  The EventKey can then be recreated for
a removal, all the _ListenerCollection and _DispatchDescriptor objects are located,
and the correct wrapped function is removed from each one.
