Hi all! I'm looking for an easy way to get informed when someone append or remove an object from a specific one-to-many relation. For example to keep a count on the parent object, with no need to query the children. There are a lot of stuff about it, but I'm not sure how to do it really:
- 1st : http://markmail.org/message/oyt57qx3247jdhgi#query:sqlalchemy%20__sa_instrument_class__+page:1+mid:wz4wkumhvnnm74yw+state:results Does not seem to work on 0.5 - 2nd : CollectionAdapter.append_with_event method let me think there is a way to register a callback somewhere, but where? - 3rd : class MyInstrumentedList(list) with appropriate decorated methods like @collection.appender. But does it work when a 'clear' is called? Did I miss something? Thanks a lot!
