Hi, Just wanted to let you know my experience with python extensions. I had been avoiding them because I had my hands full with learning Zope and DTML and SQL Methods. When I asked on the list about doing something that seemed very difficult Paul replied that a 10 line Python extension would do it. Well, yesterday I set out to do it. I have been reading about Python but had not used it yet. I looked at an example which gave me lots of clues and went at it. Within half an hour I had it working! 9 lines! What it does is it looks to see if a file exists (the name is stored in a database) in a given (NFS mounted) directory (in this case the path is also based on the first four characters of the filename). It returns an HTML link if the file exists or just the file name if it doesn't. Here is the code: import os def cadlink(file): server = 'http://netapp.regalint.com' url = '/web/so' + file[0:4] + '/' + file path = '/netapp/BBLM' + url if os.path.isfile(path): return '<A HREF=' + server + url + '>' + file + '</A>' else: return file I just call it as a function in DTML with <!--#var "cadlink(file)"--> and it works! Very cool!
