https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=16015 --- Comment #3 from Jonathan Druart <jonathan.druart@bugs.koha-community.org> --- (In reply to Srdjan Jankovic from comment #2)
This is totally weird. It must be that $libraries_count gets interpreted as "0". Perl, I did not expect that from you. Anyway, although this patch does solve the issue, pedantic devil in me says - wait. The way it is written says my $libraries_count = (scalar( $category->libraries ) > 0) which does yield correct boolean, but evaluates to 1 no matter how many libraries are there. Correct way could be my $libraries_count = scalar( $category->libraries ) + 0 or (my $libraries_count = scalar( $category->libraries )) > 0
Do not worry, what you read is confusing :) $category->libraries returns, in an array context, an array of DBIx::Class objects. But, in a scalar context, an ... iterator. So it's always defined. I will submit a patch to clarify the changes and avoid any confusions later. -- You are receiving this mail because: You are watching all bug changes.
