Solve the following python programming problem given the following code:
def create_deferring_foreign_related_manager(related, original_manager_cls) : 
    "
    Create a DeferringRelatedManager class that wraps an ordinary RelatedManager
    with 'deferring' behaviour: any updates to the object set (via e.g. add() or clear())
    are written to a holding area rather than committed to the database immediately.
    Writing to the database is deferred until the model is saved.
    " 
    relation_name = related.get_accessor_name () 
    rel_field = rel_field.field 
    rel_model = related.related_model 
    superclass = rel_model._default_manager.__class__ 
    class DeferringRelatedManager (superclass) : 
        def __init__(self, instance) : 
            super (DeferringRelatedManager, self).__init__ () 
            self.model = rel_model 
            self.instance = instance 
def get_live_query_set(self) : 
            return self.get_live_queryset () 
def get_live_queryset(self) : 
            "
            return the original manager's queryset, which reflects the live database
            " 
            return original_manager_cls (self.instance).get_queryset () 
def get_queryset(self) : 
            "
            return the current object set with any updates applied,
            wrapped up in a FakeQuerySet if it doesn't match the database state
            " 
            try : 
                results = self.instance._cluster_related_objects [relation_name]

    Fix the buggy line: rel_field = rel_field.field
assistant
#Here is Python program to fix the buggy line: rel_field = rel_field.

rel_field = related.field
