On our production servers, I’d like all exceptions to be automatically  
logged to the database.

In other C# project I wrote that meant putting a try/catch in every  
entry point method with the catch calling a generic routine which did  
the INSERT into exceptions… SQL statement.

How do I do this in rails? It would be nice if in application.rb or  
even in each controller you could do:

exception\_logger :my\_exception\_logger

Perhaps this could be implemented using filters? Hopefully rails  
already has this exact functionality built-in as I’d imagine everyone  
would need it?

Rails Exception Notifier will give you what you need. If you want, you  
can hook into it a write to the DB, but you will find that the email  
notification is plenty.
