#ignore!(update_value: false) ⇒ Object

Tells the current transaction to ignore further errors of this kind until the attribute value is changed again externally.

Parameters:

  • update_value (Boolean) (defaults to: false) —

    If set to true, the read set entry for this attribute is updated with the new external value. This means that the new value will be visible inside of the transaction until it changes again.

    Otherwise, the exception is completely ignored and will have no impact on the values displayed inside the transaction.
