I am trying to write some attribute provider for storing data inside
an SQL table as I am bored of typing parameter lists over and over
again (e.g. in every ZSQL method, in every SkinScript method etc.)
The problem now is that adding a new row to the table (and thus adding
a new object to the rack) is working well but updating an object does not.
Basically the main problem is that _objectChanged is not called in my provider.
What I did is the following:
- If an attribute of the propsheet is changed, _SetAttributeFor is called
and stores it into the cache (as I don't want to update the database for
every attribute change).
- _objectChanged is then supposed to create an sql query and execute it.
This - as said - is actually not happening, as the whole method is not called.
- My namesForRegistration looks like this:
""" return names for registration """
with self._attribs containing the attributes my provider is responsible for.
So is there any reason why _objectChanged is not called? Actually I am a bit
confused when reading the ZPatterns source which should call it.. ;-)
So which are the conditions under which it's supposed to be called?
(_objectAdded() as said before is called actually..)
I hope someone can help me :)
