TriggersΒΆ

Triggers allow to define methods of Model that are called when one of those events happen to a record:

  • On Creation
  • On Modification
  • On Deletions
  • On Time: When a condition changes over time.

The method signature is:

<method name>(cls, records, trigger)

Where records is the list of records that triggered the event and trigger is the ir.trigger instance which is triggered.

Triggers are defined by records of ir.trigger. Each record must define a pyson condition which will be evaluaten when the event occurs. Only those records for which the condition is evaluated to true will be processed by the trigger with the exception of modification triggers which will ony process the records for which the condition is evaluated to false before and evaluated to true after the modification.
