This should fix it:

        if not name and modules:
            names = []
            for m in modules:
                if isinstance(m, Formulation):
                    names.append(m.params.model_name)
                else:
                    try:
                        names.append(m['params']['model_name'])
                    except KeyError:
                        names.append(m['params']['model_type_name'])
            values['model_name'] = '_'.join( names )
        return values
