I can not persist the data in the Bank

I think I'm doing something wrong in this class because it's the only one on my system that is not persisting in the database.

What am I forgetting to make it work? The incluir() method? If I run a var_dump($log) , before calling persist($log) , the result is a variable with all the required data.

And worst of all, it does not make any mistakes either.
