  1. Faking the Web. What you need to do is to create instances of a class that has the fieldnames attribute and appropriate instance variables. One possible solution is:

    class FormData:
        def __init__(self, dict):
            for k, v in dict.items():
                setattr(self, k, v)
    class FeedbackData(FormData):
        """ A FormData generated by the comment.html form. """
        fieldnames = ('name', 'address', 'email', 'type', 'text')
        def __repr__(self):
            return "%(type)s from %(name)s on %(time)s" % vars(self)
    
    fake_entries = [
        {'name': "John Doe",
         'address': '500 Main St., SF CA 94133',
         'email': 'john@sf.org',
         'type': 'comment',
         'text': 'Great toothpaste!'},
        {'name': "Suzy Doe",
         'address': '500 Main St., SF CA 94133',
         'email': 'suzy@sf.org',
         'type': 'complaint',
         'text': "It doesn't taste good when I kiss John!"},
        ]
    
    DIRECTORY = r'C:\complaintdir'
    if __name__ == '__main__':
        import tempfile, pickle, time
        tempfile.tempdir = DIRECTORY
        for fake_entry in fake_entries:
            data = FeedbackData(fake_entry)
            filename = tempfile.mktemp()
            data.time = time.asctime(time.localtime(time.time()))
            pickle.dump(data, open(filename, 'w'))

    As you can see, the only thing you really had to change was the way the constructor for FormData works, since it has to do the setting of attributes from a dictionary as opposed to a FieldStorage object.

  2. Cleaning up. There are many ways to deal with this problem. One easy one is to modify the formletter.py program to keep a list of the filenames that it has already processed (in a pickled file, of course!). ...
