web2py can do alias but that is intended as a means of joining the
same table twice.
With the latest web2py you ca do Field('Customer','id') and it has the
effect of renaming the 'id' field. This is intended and a means to
deal with some legacy tables. It has not been tested much although it
should work. I would not recommend it.
I would suggest:
import uuid
db.define_table('Customer',Field('Customerid',unique=True))
db.Customer.Customerid.default=str(uuid.uuid4())[:6]
db.Customer.Customerid.writable=False
Mind only 6 chars there will be a probability of conflicts and they
will result in errors on insert. If the number of items is much less
than 16^6, the probability of a conflict is small anyway.
