Я пытался вынести декоратор в дочерний класс для улучшения кода, но с этого ничего не выходит. Вот собственно мой класс с декоратором:
class CacheCityManager(Geocoder):
@staticmethod
async def save_data(data) -> bool:
return await db.add_city(**data)
@staticmethod
async def get_data(city: str) -> dict:
result = await db.get_city(city=city)
return result if result else {}
def cache(self, func):
async def wrapper(*args, **kwargs) -> Optional[dict]:
func_name = func.__name__
city = args[0] if args else kwargs['city']
city = city.lower()
data = await self.get_data(city)
if data:
print(f"The city {city} were found in the cache")
return data
else:
try:
data = await func(*args, **kwargs)
await self.save_data(data)
return data
except Exception as ex:
self.logger.error(f"{func_name.upper()} error (args={args}, kwargs={kwargs}): {ex}", exc_info=True)
return None
return wrapper
и как я его вызываю:
class Geocoder:
@staticmethod
def cache(func):
pass
@cache
async def get_info_city_via_name(self, city: str) -> Optional[dict]:
data = await self._request_for_geocoding(geocode=city)
if data:
print("got info from yandex geocoder: ", data)
city_coordinates = data['response']['GeoObjectCollection']['featureMember'][0]['GeoObject']['Point']['pos']
city_coordinates = await self._get_city_coordinates(coordinates=city_coordinates)
collection = data['response']['GeoObjectCollection']
components = (
collection['featureMember'][0]['GeoObject']['metaDataProperty']['GeocoderMetaData']['Address']
['Components']
)
city_en = [component['name'] for component in components if component['kind'] == 'locality'][0]
timezone, utc_offset = await self.get_time_zone(city=city_en)
return {"city": city, "city_coordinates": city_coordinates, "timezone": timezone, "utc_offset": utc_offset}
Я хотел вынести декоратор который кеширует данные в дочерний класс но вызывать его все также с родительского класса, создал метод кеш в родительском классе который будет переназначаться в дочернем классе, но к сожалению при попытке вызова метода get_info_city_via_name я получаю ошибку:
