Issue in ActiveRecord generated reader methods
...ithout fail.
After a lot of searching, I think I have traced the problem down to

attribute directly and performs a type cast (if necessary)

accessing created_on causes type error
I assume that this is some newbie stupidity, but I haven''t found my
way around this problem. I have an ActiveRecord object fetched
from the database, and I need to evaluate the contents of the
updated_on field. However, *any* attempt to access that data in the
program results in a TypeError with the message ''no implicit conversion
from nil to integer''.
