[mod_python] Is this related to not having support to upload a file?

The problem is nothing to do with your code and there is nothing
you can do in your code to get around it.

The problem is that in mod_python.publisher it uses:

class File:
    """ Like a file, but also has headers and filename
    """

    def __init__(self, field):
                 
        # steal all the file-like methods
        for m in field.file.__methods__:
            self.__dict__[m] = getattr(field.file, m)

__methods__ is from Python 1.5 and therefore will no longer work if you
are using a newer version of Python.

  __methods__
    List of the methods of many built-in object types, e.g., [].__methods__
    yields ['append', 'count', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'].

You might be able to modify mod_python 2.7.X source code to do it
differently. You might be able to use something like:

        # steal all the file-like methods
        #for m in field.file.__methods__:
        #    self.__dict__[m] = getattr(field.file, m)

        for k in field.file.__dict__:
            if k[:2] != '__':
                v = getattr(field.file, k)
                if callable(v):
                    self.__dict__[k] = v

The file in mod_python source code that needs to be modified is:

 lib/python/mod_python/publisher.py
