Hi! I'm trying to manage a school-paper homepage with zope... during the last two weeks I got several problems that I couldn't solve with zope book and other documentation... hope there's somebody who have some answers: (1) For article management I need to login some users but this (let's call them) editors don't need the permission to view management screens (they will use html-formulars to manage their articles)... till now I couldn't find a way to login users without this permission (e.g. through a regular html-form and a dtml method). (2) Owners of dtml documents usually have the permission to change and delete their documents... but how can I discover if somebody have this (implicitly) given Owner role? (3) (Not just) For a kind of skin technology I need parameters that are user specific (REQUEST variables)... to set and analyse them may be no problem - but how can include new parameters to the old URL without deleting the old parameters? What I need is a way to add parameters to the REQUEST environment... If there are some hints in the official documentation I would be very interested in... otherwise I hope somebody can help with some smart examples or a hint. -- Stefan Berthold <dingx@web.de> Zivilist in Lauerstellung GnuPG: 4222 F68D E39F FE43 423A 5624 3A3D F1D7 4EF0 C45A FAX/VoiceBox: +49 180 50529 6341739
