Doctrine 2 WTFs

  1. One select for each insert (can be solved by using getReference instead of find)
  2. No error for wrong reference (can be solved by using getReference instead of find)
  3. No error for non-existing fields (can be solved by defining setters)
  4. No error for invalid data (can be solved by using strict mode in MySQL but not in SQLite)
  5. Manual locking and transaction handling for incrementing a column (can by bypassed by using DQL)
  6. One query for each loop iteration (can be bypassed by using DQL)
  7. Auto-generated code for proxy
