How to check the manytomany field for the presence of an object in it?

Question

Django

There is a user model, and a product

class User(AbstractBaseUser):
  purchased = models.ManyToManyField('Movie', verbose_name='Купленные товары', blank=True)

class Movie(models.Model):
  title = models.CharField(verbose_name='Название', max_length=100)

How can I check if there is a video in the purchased field?

Answer 1

As an option

movie1 = Movie.objects.get(pk=1)
movie2 = Movie.objects.get(pk=2)
User.objects.filter(pk=1, purchased__in=[movie1, movie2]).exists()

or

movie = Movie.objects.get(pk=1)
user = User.objects.get(pk=1)
user.purchased.filter(pk=movie.pk).exists()
