source: main/waeup.sirp/trunk/src/waeup/sirp/students/browser.py @ 7098

Last change on this file since 7098 was 7097, checked in by Henrik Bettermann, 13 years ago

Implement StudentFileNameChooser? and StudentFileStoreHandler?.

Define viewlet manager FileManager? in viewlets.py and define display and upload viewlets for the StudentClearanceDisplayFormPage?.

Also define image views. Since these views are part of the viewlets they are defined also in the viewlets module. In browser.py we only add an empty files_changed list attribute to the StudentClearanceManageFormPage?. This will be needed for logging (to be done).
