Actually that helps alot and i had infact resolved to and was in the process of doing so (i know that about python modules.. ;) but i might be missing something)
But, why does this work in the context of an application (eg. pylons app). Basically, calling Base.create_all() in some init_db method of an application works without having to import all the modules in, say, myapp.models.__init__.py Suggestions are welcome, though i'm considering the question answered Thanks alot and Regards, On Mar 30, 4:39 pm, "King Simon-NFHD78" <simon.k...@motorolasolutions.com> wrote: > This is just the way Python works - code inside a module is only > executed when that module is imported.
