[Erp5-dev] how to get base categories from type information

[Bartek Gorny]

Hello

Anybody knows how to do this: get a list of base categories for a
portal_type from the Type Information?

The point is to get something like what you can get from an instance
(by object.getBaseCategoryList()), but not from an instance, but from
a portal type definition - like collecting all property sheets hooked
to it and adding base categories assigned from ZMI. I'm sure there is
a way to do it, but can't figure out how. Can you help?

ERP5Type.getInstanceBaseCategoryList have been added very recently for this
purpose, but this is still unstable API.

Almost, but not quite - the function is looking for class ("klass") by
deriving its name from the name of the portal type - which works as
long as they are the same. But they can be different, if you have
multiple portal types from the same class - then you don't get any
property sheets.

You are 100% right, both ERP5Type.getInstanceBaseCategoryList and
TranslationProviderBase.createInitialPropertyTranslationDomainDict suffer
from this problem.
Afterall, the best way to know the properties / categories of objects created
by a given ERP5TypeInformation is to probably to call its factory method and
introspect the returned object, like does ERP5Type.getInstancePropertyMap.
