Good day! When I create,modify,delete some object, I must create,modify,delete an another object in my entire application. SQL solves problem by trigger.
As, I understand, event system must help. There are two questions. How make event for specific class only? And second - what event I need to use for insert/update?
post-insert works fine, but after transaction so nothing writes to database. save or save-update fires before main objects writes to database.
