I can explain further--relational databases have certain capabilities that objectstores don't, but the same is true in reverse. In a relational/sql db you can't add properties to an object unless you add them to all other objects of the same type. You can't get polymorphism. And 'many to many' relationships require an intermediary table. The problem I'm having is the web2py data model is entirely relational/sql. Bigtable is --essentially-- an objectstore. Using web2py with bigtable means I am left with the least common denominator in terms of functionality. I can't use the relational functionality that bigtable doesn't support, AND I can't use the non-relational functionality that bigtable supports but web2py doesn't. I'd prefer to use an objectstore, but what's the point if I can only get the subset of functionality that an objectstore shares with an rdb? It's like the worst of both worlds.
I looked through the source for web2py last night and I can see that getting Admin to work under GAE would be a large task. As I said above, I love web2py, but the relational/sql modality for the web2py models is something I don't like. Rails and django both have something closer to an ORM in their models. This is the one area where web2py suffers in comparison to its competitors. How about a real ORM in web2py? A way to define data models using classes, including polymorphism, and then screw the sql JOINS and such? Just a request.
