What you’ll accomplish
Remove an unfinished canvas signature before confirmation. This guide follows the supplied Delivery Note module’s live hooks, controller actions, model rules, views and stored side effects.
Follow these steps
- Draw the signature.
- Select Clear before submitting.
- Verify the canvas is blank.
- Draw the correct signature.
- Select Confirm Delivery only when satisfied.
Fields and options to review
- Clear button calls the Signature Pad clear method
- No server record is changed until the form is submitted
Rules the system enforces
- Clearing affects only the current browser canvas.
- It does not create a sign_failed event.
- After a successful submit, the note is signed and the canvas workflow is no longer available.
How to confirm it worked
- Only the final submitted signature is stored.
Safety checks and troubleshooting
- Do not reload or close the page before submitting if the signature is still needed.
Stay within the supported flowDo not force database values, expose secure tokens, bypass permission checks, replace a stored signature or invent a status or interface that the supplied code does not implement.
