Given 3 tables: COURSES, REQUESTS, CLASSROOMS joined properly in the model (hopefully).
I want to either:
1) show all courses, but prohibit (onclick) enrollment in a course based on its classroom reaching capacity (static value in table per classroom).
Or, 2) do not show courses that have reached their classroom capacity through enrollment.
So, I think I have to count all requests for a given course, then show courses whose requestcount is <= classroom.capacity.
Can anyone point me in the right direction on how to do this, and/or provide feedback on my logic? I'll provide more details and code if you might find it useful...
Thanks in advance........
