your code never writes the updated votes string. and i'm not sure that
using the "in" operator on a string like that will give you the results
that you want.
you probably want another table say votelog
db.define_table('voetlog',
Field('content_id', 'reference content'),
Field('user_id', 'reference auth_user)
then check if logged in user has a record in votelog for that content
before incrementing the content vote and adding a row to the votelog table.
