Hi
I have created two classes. 1- course 2- subject. and for relation between two classes.
I am using the object relations datatype for identifier(subject). I wanna fetch the all subject name in course but whenever use this code.

{$node|attribute(show)}

No attribute shows. i have try more code but there is no value display about Attribute, type etc.Ex.

{$node.data_map.subject|attribute(show)}
{$node.data_map.subject.content|wash()}


Please suggest me about this problem.
Thanks & Regards
