C. Validation & Business Logic

1. Dependency Checks (Pre-Delete) \listing-tanker-manage

Before deleting a tanker, the system ensures it is not assigned to an active Carrier.

ModuleEndpointFilter Logic
🚛 Carriers/carriers/getQuerytankerId
Error: "Unable to delete Tanker due to tagging to carrier."

2. Unique Tanker Number Validation \add-tanker-manage

  • Trigger: On Save.
  • Logic: Calls /tankers/getQuery. Filter: tankerNumber||$eq||{input}.
  • Error: Blocking error: "Tanker number already exists".

3. Date Formatting \add-tanker-manage

  • Library: Luxon (DateTime).
  • Logic: Before saving, all date fields (malaysiaRoadTaxExpiry, etc.) are converted to standard yyyy-MM-dd format. Null strings converted to null.
