Thanks for the help. I almost have this up and running, but I have found one preplexing issue.
My current code base has a very extensive test suite. As part of this test suite, I have my test fixtures setup and teardown databases, mappers, and just about every SA related. This is meant to help keep each test clean from anything remaining from the previous test. As part of the setup and teardown for the tests, I explicitly call sa.orm.clear_mappers() to clear out all mappers that were setup in the previous tests. This was not a problem before the declarative code change-over because each time I setup the DB's for the tests I have the system call an initialization method that sets up all metadata, mappers, etc. But now, with the mappers being created behind the scenes I don't have any way to force the system to recreate the metadata or mappers. Is there some way to "clear" the declarative layer and have it regenerate all automatically created metadata and mappers? -Allen On Mon, Apr 28, 2008 at 5:07 PM, Michael Bayer <[EMAIL PROTECTED]> wrote: > > > On Apr 28, 2008, at 5:42 PM, Allen Bierbaum wrote: > > > > > So, if I understand this right, I could import a "base" module that > > does a lazy creation of the Base class with a metadata object and then > > just use that base class everywhere I need it for the declarative > > class definitions.
