Query error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'slot_start' in 'field list'
⚠️ Current System Behavior
Current Logic:
  • The API returns ALL available slots from availability_cache
  • If 2 consultants are free at 10:00, the slot appears ONCE in the API response
  • When a client books, only ONE appointment is created
  • The second consultant's slot remains available
Potential Issue:

If you want only one appointment per time slot regardless of consultant count, we need to:

  1. Group availability_cache entries by time slot
  2. Show each time slot only once to clients
  3. When booked, mark ALL consultants as busy for that slot
Solution Options:
  1. Keep current behavior: Multiple consultants = multiple appointments possible
  2. Single appointment per slot: First booking blocks the entire time slot
  3. Consultant selection: Let client choose which consultant they prefer
