Your tables already exist in the database. However you must have
deleted your /app/databases/*.table files, so as far as web2py is
concerned it is a blank database.
To remedy the solution, add this to each of your define table statements
db.define_table('.....', fake_migrate=True)
Run your code once, this should create the needed
app/databases/*.table files, then remove th fake_migrate lines and you
should be all set.
