You could use the Bytes() -schema whose InputWidget is a file upload field by default.
The content class or adapter for your form should look like this:

class IMyClass(Interface):
   [...]
   csv=Bytes(
       [...]
   )

class MyClass(object):
   [...]
   get_file(self):
      [... put database code here that returns a csv file - if you like ...]
   set_file(self,data):
      [... data contains you file's content. process it as you like ...]
   csv=property(get_file,set_file)

Just use an <editform> to get a file upload view.
