I have this class called Sample that is coded in python only. This class needs to contain uploaded files. Currently, it subclasses the following: CatalogAware, OFS.SimpleItem.Item, Persistent, Implicit, AccessControl.Role.RoleManager, OFS.ObjectManager As a test, I tried the following command where sample1 is an instance of Sample: $ python Client.py -usuperuser:123 http://localhost:8080/Test/sample1/manage_addFile id="forms.html" file:file=/home/superuser/forms.html The file was added to sample1's parent folder (http://localhost:8080/Test/forms.html) instead of itself (http://localhost:8080/Test/sample1/forms.html). Why is this so? Is there any particular Class I need to subclass in order for Sample to contain File objects? Thanks, Meng Kuan
