Hello Zope community, I just installed Zope-2.9.4 in a windows XP SP2 . I'm making a web site that the visitors should: A) Upload a file to the server B)After the file is uploaded , I have write a python program to encode the file C)When the encoding is finish, user must download the file back to his machine. I'm very new to Zope and I choose it because I thought it should have an easy and good communication with python. Since I have terminated the python program that does what I want, I have no idea how to accomplish the requests above. A -> I know I will need external access to the file system, is there a product that can help me in that ? B -> my program works as I want like a python program , it will need any modification so I can use it in Zope ? C -> I think I will need also some kind of progress indicator so the user can know when the encoding is done (some time takes more than a minute). Any ideas how the user will download back the file? should the download begin automatically after the encoding ? Thanks in advance...
