[Dbix-class] Bug: update_or_create() and auto-inflate/deflate

[Bernhard Graf]

I have a table class with a 'created' column that is defined as:

__PACKAGE__->inflate_column('created', {
    inflate => sub { DateTime::Format::MySQL->parse_date(shift) },
    deflate => sub { DateTime::Format::MySQL->format_date(shift) },
});

In my Application the call looks basically:

    $date = DateTime->new(...);
    $rs->update_or_create({
        id => $id,
        other => $other_data,
        created => $date,
    });

Everything works if row is created.

But the next time (update) it fails saying:

Cannot compare a datetime to a regular scalar at /usr/lib/perl5/vendor_perl/5.8.5/x86_64-linux-thread-multi/DateTime.pm line 1395.

It seems that one of the dates to compare is a scalar while the other is
a DateTime object (DateTime overloads comparison operators, so compare
operation end in DateTime->compare()).

To work correctly, update_or_create() should compare both dates in
deflated state, right?
