Say I have a Strategy table which has a polymorphic relationship with 3 other tables of Strategy 1, Strategy 2 and Strategy 3.
I need to count how many records there are in just one of the linked tables (i.e. Strategy 2) that match a criteria, i.e. the value of a field is > 150.
I really can't get my head around how to do it.
Just to give an idea of the relationships...
User HAS MANY Strategies
Strategies HAVE MANY "sub" strategies.
