How to correctly count the number of ratings for one id in the model?

Question

Django

Hey!
Tell me how you can get data from a certain id, let's say the number 5.
There is a model

class MasterReviewRating(models.Model):

value = models.SmallIntegerField(verbose_name='Оценка', blank=True)
master = models.ForeignKey(NewMaster, on_delete=models.CASCADE, verbose_name='Выберите мастера')

@property
 def count_four(self):
      return MasterReviewRating.objects.filter(Q(master_id=self.master_id) | Q(value=4)).count()

 def rating_count_four(self):
        if self.count_four == 0:
            return f'нет оценок'
        elif self.count_four == 1:
            return f'{self.count_four} оценка'
        else:
            return f'{self.count_four} оценки'

Now the model considers id + number of ratings. And you need to display only the master, let's say number 1 and the number of its fives.
Went through all the options, does anyone have such experience.
Thank you.
