in Collection.pm, i have
sub count_assets {
my $self = shift;
return CollectionAsset::Manager->get_collection_assets_count(
require_objects => ['asset'],
query => [ collection_id => $self-
>collection_id, @_ ],
);
}
sub count_assets_published {
my $self = shift;
return $self->count_assets('asset.pubstatus' => 'published',
@_);
}
and later:
my $count = $collection->count_assets_published(
[ \'t2.pubdate >= NOW() - INTERVAL ? DAY' => $num_days ] #
t2 ~> asset
);
i can't refer to 'asset.pubdate' in this query param, because RDBOM
insists i use a scalar-ref here, and wisely avoids doing
substitutions when handed a scalar-ref, and mysql won't let me refer
to the table by its real name once it has been aliased.. since the
generated query aliases asset as t2, i have to use t2 here, though
not elsewhere. needless to day, it's a little confusing, especially
to future-maintenance-programmer.
any advice?
another thing i am struggling with a bit is allowing such helper
methods to modify both the query and manager_args. in the above
example, require_objects=>['asset'] isn't required in the basic case
where it exists, but is there because methods like
count_assets_published need to refer to the assets.. seems common
enough, so maybe there is already a convenient way to merge manager
args in this case?
here is a bit of ugliness that hints at what i am after:
sub count_assets {
my $self = shift;
my ($manager_args, $query_args) =
_separate_manager_query_args(@_);
return Plex::RDBO::CollectionAsset::Manager-
>get_collection_assets_count(
@$manager_args,
query => [ collection_id => $self->collection_id, @
$query_args ],
);
}
sub count_assets_published {
my $self = shift;
my ($manager_args, $query_args) =
_separate_manager_query_args(@_);
return $self->count_assets(
require_objects => ['asset'], @$manager_args,
query => [ 'asset.pubstatus' => 'published', @
$query_args ]
);
}
sub _separate_manager_query_args {
my @manager_args = @_;
my @query_args;
foreach my $i (0..$#manager_args) {
if ($manager_args[$i] eq 'query') {
@query_args = @{ (splice @manager_args, $i, 2)[1] };
last;
}
}
return ([EMAIL PROTECTED], [EMAIL PROTECTED]);
}
any advice? ;)
