in reply to Re: Class::DBI find_or_create method inserts record but $obj->id is undef
in thread Class::DBI find_or_create method inserts record but $obj->id is undef

Perrin,
Thank you for the reply. Perhaps I am failing to grok how to delete the field from the CGI object, for instance if I do this:

$q->param('class_id') = undef;

I get "Can't modify non-lvalue subroutine call".
Is there some other way to alter the object that will work here?
TIA
jg

      Mea culpa. Thanks for the reminder I have been away from Perl for a good while.

      Unfortunately the Class::DBI update() method does not work unless the $obj has an id defined and part of the problem here is that the insert id isn't in $obj unless find_or_create gets an explicit undef or an explicit $id.
      TIA

        That's why I said you should delete the value AFTER the call to find_or_create. Alternatively, you could replace your loop with this: 
        foreach my $field (grep { $_ ne 'id' } $q->param) {
