Solve the following python programming problem given the following code:
def contribute_to_class(self, cls, name) : 
    super (JSONField, self).contribute_to_class (cls, name) 
    signals.post_init.connect (self.post_init, cls) 
    def get_json(model_instance) : 
        return dumps (getattr (model_instance, self.attname, None)) 
setattr (cls, ('get_%s_json' % self.name), cls) 
    def set_json(model_instance, json) : 
        return setattr (model_instance, self.attname, loads (json)) 
setattr (cls, ('set_%s_json' % self.name), set_json)
