Having just installed a new server, I ran into the following problem. A
relationship fails to load with the message:
Need a Column, got <column name>.
This message is coming from this method within Class::DBI::ColumnGrouper:
sub add_column {
my ($self, $col) = @_;
# TODO remove this
croak "Need a Column, got $col" unless
$col->isa("Class::DBI::Column");
$self->{_allcol}->{ $col->name_lc } ||= $col;
}
The verstion of CDBI is 3.0.13
On the other servers I have version 3.0.1
sub add_column {
my ($self, $name) = @_;
return $name if ref $name;
$self->{_allcol}->{ lc $name } ||= Class::DBI::Column->new($name);
}
OK, so this explains why code that used to work quit doing so. The question
is - what should I be doing? The code which is causing me to go here is:
$class->__grouper->add_group(TEMP => $accessor);
I swiped this from Relationship::IsA whose code hasn't change as far as I
can tell - and it probably fails too.
The purpose of this statement is to create an accessor which stores the data
indicated by the relationship.
Is there a new paradigm for this expression which I should be switching to?
Or is this an omission given the TODO statement above?
Cheers,
Kate
