web2py

I have a table defined in web2py db.define_table( 'pairing', Field('user',writable=True,readable=True), Field('uid', writable=True , readable=True) ) This table needs to have user and uid combination being unique. I have looked through the web2py documentation , but there isn't direct way to define composite key . How do we define composite way in web2py It depends on what you are trying to do.

As for web app fast, I've checked out Django, Turbo Gears and Py2Web. In spite of spending a lot of time reading, I still have no clue which one I should use. 1) Django certainly has the nicest online

Which of these two frameworks is better suited to a developer with 11 months experience. I have decided to learn python for my server side coding and wanted to know which of these would be better suited for someone at my skill level. I have just spent a few days playing around with web2py and really like it and i am wondering if Django offers something more that i am missing out on? PS.

This is a wonderful
