From c6735fecc75a759b6ec2634e47690e809ee2a83a Mon Sep 17 00:00:00 2001 From: Agustin Moyano Date: Mon, 9 Mar 2020 12:05:03 -0300 Subject: [PATCH] Bug 24830: Fix parse_prefetch recursion and +count cases When a child of a prefetched element wasn't found on element's prefetch_whitelist, no prefetch element was returned.. including element it self. Now we return element's name if no child was found. Also, embeded keys that ended with +count where taken literaly. Now we search the correct key by stripping _count of embedded element if it was declared as "is_count" --- Koha/REST/Plugin/Query.pm | 22 +++++++++++++--------- 1 file changed, 13 insertions(+), 9 deletions(-) diff --git a/Koha/REST/Plugin/Query.pm b/Koha/REST/Plugin/Query.pm index 46296e638a..ea6695ff37 100644 --- a/Koha/REST/Plugin/Query.pm +++ b/Koha/REST/Plugin/Query.pm @@ -124,7 +124,7 @@ Generates the DBIC prefetch attribute based on embedded relations, and merges in return unless defined $embed; my @prefetches; - foreach my $key (keys %{$embed}) { + foreach my $key (sort keys(%{$embed})) { my $parsed = _parse_prefetch($key, $embed, $result_set); push @prefetches, $parsed if defined $parsed; } @@ -353,20 +353,24 @@ sub _merge_embed { sub _parse_prefetch { my ( $key, $embed, $result_set) = @_; - return unless exists $result_set->prefetch_whitelist->{$key}; + my $pref_key = $key; + $pref_key =~ s/_count$// if $embed->{$key}->{is_count}; + return unless exists $result_set->prefetch_whitelist->{$pref_key}; - my $ko_class = $result_set->prefetch_whitelist->{$key}; - return $key unless defined $embed->{$key}->{children} && defined $ko_class; + my $ko_class = $result_set->prefetch_whitelist->{$pref_key}; + return $pref_key unless defined $embed->{$key}->{children} && defined $ko_class; - my $prefetch = {}; - foreach my $child (keys %{$embed->{$key}->{children}}) { + my @prefetches; + foreach my $child (sort keys(%{$embed->{$key}->{children}})) { my $parsed = _parse_prefetch($child, $embed->{$key}->{children}, $ko_class->new); - $prefetch->{$key} = $parsed if defined $parsed; + push @prefetches, $parsed if defined $parsed; } - return unless scalar(keys %{$prefetch}); + return $pref_key unless scalar(@prefetches); - return $prefetch; + return {$pref_key => $prefetches[0]} if scalar(@prefetches) eq 1; + + return {$pref_key => \@prefetches}; } sub _from_api_param { -- 2.25.0
