Solve the following python programming problem given the following code:
def _filters_to_query(self, includes, excludes, serializer, q = None) : 
    "
        Construct Django Query object from request.
        Arguments are dictionaries, which will be passed to Q() as kwargs.

        e.g.
            includes = { 'foo' : 'bar', 'baz__in' : [1, 2] }
          produces:
            Q(foo='bar', baz__in=[1, 2])

        Arguments:
          includes: TreeMap representing inclusion filters.
          excludes: TreeMap representing exclusion filters.
          serializer: serializer instance of top-level object
          q: Q() object (optional)

        Returns:
          Q() instance or None if no inclusion or exclusion filters
          were specified.

    def rewrite_filters(filters, serializer) :

        for (k, node) in six.iteritems (filters) : 
            filter_key = node.generate_query_key (serializer)
