Hi there,

I checked in an example demonstration how to use megrok.traject with 
sqlalchemy in Grok. It's the equivalent of megrok.rdbexample in 
functionality, but the way the code is structured is quite different.

You can check it out like this:

svn co svn://svn.zope.org/grokapps/trajectrdbexample/trunk trajectrdbexample

Note that it is a lot more verbose than megrok.rdb. This is deliberate 
to demonstrate how it promotes a cleaner separation of concerns between 
SQLAlchemy-based models and Grok.

If we used megrok.rdb's alternate model-based configuration mechanism 
the example could be shrunk down, but that would be at the cost of this 

The example could then be shrunk down even further by using megrok.rdb's 
SQLAlchemy declarative integration. That combined example I'll leave to 
the future, though. :)
