114 Allows access to object for its owner.
116 There are endpoints that should allow access for the object owner even if they
117 do not have the required permission, e.g. access an own reserve. This can be
118 achieved by defining the operation as follows:
120 "/holds/{reserve_id}": {
123 "x-koha-authorization": {
135 my ($c, $authorization, $user) = @_;
137 return unless $authorization->{'allow-owner'};
139 return check_object_ownership($c, $user) if $user and $c;
142 =head3 allow_guarantor
144 Same as "allow_owner", but checks if the object is owned by one of C<$user>'s
149 sub allow_guarantor {
150 my ($c, $authorization, $user) = @_;
152 if (!$c || !$user || !$authorization || !$authorization->{'allow-guarantor'}){
156 my $guarantees = $user->guarantees->as_list;
157 foreach my $guarantee (@{$guarantees}) {
158 return 1 if check_object_ownership($c, $guarantee);
162 =head3 check_object_ownership
164 Determines ownership of an object from request parameters.
166 As introducing an endpoint that allows access for object's owner; if the
167 parameter that will be used to determine ownership is not already inside
168 $parameters, add a new subroutine that checks the ownership and extend
169 $parameters to contain a key with parameter_name and a value of a subref to
170 the subroutine that you created.
174 sub check_object_ownership {
177 return if not $c or not $user;
