This is just the way Python works - code inside a module is only executed when that module is imported. If you don't import myapp.models.notes, then the class definitions never get executed.
One solution is to import all the sub-modules in your bootstrap.py before calling create_all. Another is importing the submodules inside the myapp/models/__init__.py Hope that helps, Simon -----Original Message----- From: sqlalchemy@googlegroups.com [mailto:sqlalchemy@googlegroups.com] On Behalf Of eric cire Sent: 30 March 2011 14:57 To: sqlalchemy Subject: [sqlalchemy] Re: sqlalchemy.exc.NoReferencedTableError: Could not find table with which to generate a foreign key After investigating further, i have the impression that the problem occurs when models are in different modules (notes.py & users.py in this case) but if the models are in the same module eg. myapp.models.__init__.py, the tables are created. I'd still like to know why this is happening because i don't intend to put al my models in the same module..

The following is done: create an engine (sqlite:///notes.db) call Base.create_all(bind=engine) The Base class is the same for the models and the bootstrap.py module, but i still get a noreferencedtableerror... it basically doesn't create the database tables when bootstrap.py is called..
