Accualy I don´t have to do that.
Have a look at Itamar Shtull-Traurings and Heiko Stoermers
FlatDatabase:
class EntryDataSkin(DataSkin):
"""
Flat Database entry.
"""
meta_type = "Entry DataSkin"
...
def manage_change(self, REQUEST, RESPONSE):
""" Change properties """
for prop in self.database_properties.propertyMap():
name=prop['id']
if REQUEST.has_key(name):
if 'w' in prop.get('mode', 'wd'):
value=REQUEST.get(name)
setattr(self, name, value) <<<<
RESPONSE.redirect(REQUEST.URL1)
But as I noticed the "properties" was saved as
attributes not as properties in a propertysheet.
I can live with that, but I still would like to know if and
how to use propertysheets provided by a DataManager
inside a Pyhton DataSkin?
