Is there a reason why I can't set the first value of an array to NULL? I
want to store this {NULL, 1, 2, 3} by way of an RDBO array column but I
think the following function from Rose::DB 0.737 is preventing me from doing
so:
sub format_array
{
my($self) = shift;
my @array = (ref $_[0]) ?
That's ok, if you could just issue another release on CPAN just for this bug
that would be great :P
Thanks John!

I just meant that it'd be a change in historic behavior that could
break some people's code when they upgrade (not that RDBO is 1.0 yet,
but it's still nice to avoid this kind of thing, if possible).
This is off-topic, but what lies ahead on the road between RDBO 0.7xx and
1.0? Are there
Is there a way to set a RDBO boolean column to NULL? It seems to me
that undef evaluates to FALSE.
$obj-bool_column(undef);
$obj-save;
print $obj-bool_column; # 0
Should I be creating my own column class for this?

Thanks for this!

Which dies because $count is assigned zero, making the statement

Whoops, careless copy/paste. That's fixed in SVN now.
Great, thanks very much!
2. If I am counting objects related by a many-to-many where the

What you need is
COUNT(DISTINCT some_function_that_joins_all_args(arg, arg))
because you really want 4,5 to be counted distinctly from 4,6.
So coalesce definitely doesn't do it.
Right,
It seems like a simple concat (pg operator ||) would work in this case:
SELECT COUNT(t1.a_id ||
It seems like a simple concat (pg operator ||) would work in this case:
SELECT COUNT(t1.a_id || t1.b_id)
Ugh, I forgot the DISTINCT again:
SELECT COUNT(DISTINCT t1.a_id || t1.b_id)
But this is tested and works properly too.
Hello,
I am trying to move to related_count() method calls in my RDBO (0.764)
app, they seem so convenient and quick. I am running into two separate
bugs, however:
1. A fatal error is thrown when the object count is zero. I believe
this is happening around line 2749 of MakeMethods::Generic:
It's on the list, but not at the top just yet. (Even just collecting
and editing recipes takes time.) If someone else wants to head this
up, let me know.
Is there a Wiki installed somewhere we can start working on in an
ad-hoc fashion?
. If you set $a-b({ name = 'test' }), will Rose
know to map the b back to the a as well as mapping the a to the b?
Which is a cleaner approach?

I have gone down a similar path before,

The short story is that a map_record is not designed to be
manipulated, it's only there for convenience when fetching related
objects from a many-to-many relationship call, such
I feel like I'm repeating work here -- I've got a similar set of
functions that serialize and restore trees of objects, only I'm doing
this in a very specific way, keeping only what I want from specific
classes (not reusable).
What are the chances of this object_tree code making it into 0.764 or

No, the Manager does no caching. Given the code you posted, I can't
see a way that this could ever happen. Map records only (optionally,
and not by default) appear when you're asking for a many-to-many
relationship in your Manager call using the with_objects or
require_objects parameters.
. Do I have to do this
after the save()? Seems trivial in the above example but these
operations happen in completely separate areas in my code.
Cheers,
Derek

Hello,
Is it possible to get sequence support in RDBO? I know that sequences are
supported for primary key generation, but I have a few cases where they are
used for non-keyed columns, and I find myself writing (and re-writing) this
into my classes:
sub insert {
my $self = shift;

Hello,
What is the recommended idiom for deleting a single object from a
one-to-many relationship? Using the textbook example,
$p = Product-new(name = 'Kite');
$p-prices({ price = 1.23, region = 'US' },
{ price = 4.56, region = 'UK' });
$p-save; # database is modified here

I agree that performing a group of actions in a single transaction is one of
the prettiest features of RDBO, and I also like John's approach to making
these shortcuts to Manager routines. I find myself constantly re-writing my
table relationships for manager calls.

I see that as of 0.546, form validate() calls get passed to sub-forms by
default,
* Added a cascade parameter to validate(), which defaults to true.

Which is great - exactly what I needed! But there is an order-of-operations
problem for me, because

I am using RDBO in conjunction with Rose::HTML::Form for the first time, and
wonder if there are any guides or examples out there showing some
conventional integration techniques. Specifically, how best to use RHF's
