Ok thanks. Just one more thing, so if there are around 10 tables in my dump
file which is loaded into the database and I have set migrate = False, as I
dont make any modifications or table alterations in the db.py. How can I
get these tables listed in the db.tables command in the web2py shell. Its
really confusing me. I ran my app with migrate = False, since the table
definitions are all there in dump file. But in the web2py shell it just
shows the auth_tables with the default declerations only.
