When modelling the relationship between SubTopicName and TopicName and then trying to save we get the following error

Relationship TopicName in entity SubTopicName is a to-one relationship, but its destination attribute(s) does not match the primary key of the destination entity.

I would suggest reimplementing the relationship as a method invoking a fetch for the appropriate SQL. You might also define a to-many relationship, and return the first object from the array.
