Is there a way to identify why the database ROLLSBACK in a Rails application?

I'm trying to update a model object, and it keeps rolling back. Occassionaly protesting that it is a validation error. But it doesn't point to what is actually failing.

In the end, I tried to delete it, but in the deletion, it still fails validation.

Is there a way to debug this and find out exactly why/what is causing this?

Thanks

A typical response to an update or delete:

ActiveRecord::RecordNotSaved: ActiveRecord::RecordNotSaved

And for more evidence, this is the stack from the appication when I try to create a new object:

At a guess, these lines:

.. mean that you have a uniqueness validation that's failing because the null value is "taken".
