Чего мне нужно достичь. *Публикуйте «нравится», «Не похоже», анализируйте, сколько лайков было сделано с определенного дня на день, API должен возвращать агрегированные данные по дням. Активность пользователя конечная точка, которая покажет, когда пользователь входил в систему в последний раз и когда он делал последний запрос к серверу *.

Чего я уже достиг. Использование двух моделей Пользователь, Сообщение, вход пользователя, регистрация и создание сообщения. Реализована аутентификация токена JWT

Мой код в приложении «api»: models.py

  from django.db import models
from django.contrib.auth.models import User
from django.utils import timezone


class Post(models.Model):
    title = models.CharField(max_length=50)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    post_like = models.ManyToManyField(User)
    author = models.ForeignKey(User, on_delete=models.CASCADE)

    def __str__(self):
        return self.title
 

serializers.py

    class Meta:
        model = Post
