I have a Training Collection and a Rate Collection.
A user can have multiple Training, and for each Training the User can add a unique Rate
A Training can have multiple User and each user can add a unique Rate
I want to filter a specific User’s Training list which have no Rate yet.
I use this filter, but it shows all the training (with or withour rates).
I’m trying to figure out how to filter it but wasn’t able to find out.
