How are you trying to save the data? The admin interface?
your own code?
If it is your own code, please paste an example so we can
look at the
problem. Also, describe exactly what it is that you do when
you get the
duplicates.

One solution is to change your model in such a way that it
will only
accept unique records. That way, it would work on the first
attempt, but
it won't stick the duplicate in.

Thanks!
