hello, I need different DTML-Document-"Templates" (different source and properties) for different folders, but I don't want to create a (Z)Class for everything. So when a user adds a DTML Document in the folder 'Students' he should get the 'Students'-Default-DTML-Document (with properties like name, address, email), when adding a DTML Document in folder Events he should get the Event-Default-DTML-Document (properties like date, headline, description). My idea is a "patch" for DTMLDocument/addDTMLDocument: When a DTML Document with the name "standard_dtml_document" can be aquired, this will be cloned/copied into the new created DTML Document... with source and properties. So I can put my students-default-DTML-Document as "standard_dtml_document" into the students-folder, dito for my events-default-DTML-Document. Question: How can I "overwrite" (in a Product) the original addDTMLDocument with my own method (code see below), so I don't have to change OFS/DTMLDocument.py(thinking of ZOPE-updates)? Or is there already an existing solution which I did not see? Thank you, maik. *** def addDTMLDocument(self, id, title='', file='', REQUEST=None, submit=None): """Add a DTML Document object with the contents of file.
