The problem seems to be that, according to the docs, RunmodeDeclare
will capture variables passed as $self->baz(1, "me") as well as from
the query object. So 'edit ($id)' means $id will capture anything
passed into the rm. What seems odd is that the dfv errors hashref is
also captured in the first arg shifted from @_:
That's the issue: the arguments aren't shifted off @_, they're assigned
from it. CAP::RD rewrites this:
runmode something ($some, $variables)
into this:
sub something {
my $self = shift;
my ($some, $variables) = @_;
$some = $self->query->param('some') unless defined $some;
$some = $self->param('some') unless defined $some;
...
In other words, it tries treating the signature as a regular method
signature first, and only falls back to looking in $self->query or
$self->param if the variables are still undefined.
And it also explains why you got the errs hashref in both $id and $errs,
since @_ is still unchanged.
runmode edit ($id) {
my $errs = shift;
warn Dumper $id; # contains the dfv errors hashref
warn Dumper $errs; # also contains the dfv errors hashref !!
[ .. ]
}
Of course it all works fine if I switch back to conventional runmode
handling, or to AutoRunmode.
The other solution would be to recognise that dfv_error_page passes the
dfv hashref as the first argument, and name that in your signature:
runmode edit ($errs, $id) { ...
That way, $errs is picked up from @_, while $id is picked up from either
$self->query or $self->param (provided dfv_error_page doesn't pass
additional parameters).
Hi Rhesa,
OK, first thoughts (without actually trying it), are that "runmode edit
($errs, $id)" would work OK for the error return from update(), but not
when edit() is called from the query - as /myapp/edit/1 - since the
value of '1' would get taken into $errs, leaving $id undef. No?
