Я пытаюсь создать вложенный сериализатор, используя DJANGO REST FRAMEWORK.
Но я не знаю, как использовать методы создания обновлений в serializer.py. Я уже создал модели и некоторые работающие сериализаторы. И я хочу, чтобы весь этот сериализатор был доступен для записи и редактирования, но я не знаю, как это сделать, я пытался, но не смог получить реальный результат. Вот мой код.
from rest_framework import serializers
from ..models import about, education, work, project, skill, language, hobbies, techonogies

def get_user(self, obj):
return obj.user.username
И educations, works, projects, languages, skills, hobbie, tech это все связанные названия_ моделей
