Because in the lambda is call somewhere inside web2py whete is_empty
is not in the scope.
db.policies_and_strategies.url.represent = lambda value:
local.is_empty(value) == None or A('url',_href=value)
it is a python weirdness. You can fix it like this:
db.policies_and_strategies.url.represent = lambda
value,is_empty=local.is_empty: is_empty(value) == None or
A('url',_href=value)
