我尝试遍历与Album QuerySet关联的Review QuerySet，以便收集Review QuerySet中的总评分。（例如，9 + 8 + 7 + 9 = 33）以下是我的模型：

class Album(models.Model):
    creator = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    artist = models.CharField(max_length=255)
    title = models.CharField(max_length=255)
    # image =
    rating = models.IntegerField(
        choices=[(i, i) for i in range(1, 11)],
        validators=[MaxValueValidator(10), MinValueValidator(1)],
        default=10,
    )
        ...

class Review(models.Model):
    reviewer = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    album = models.ForeignKey(Album, on_delete=models.CASCADE)
    rating = models.IntegerField(
        choices=[(i, i) for i in range(1, 11)],
        validators=[MaxValueValidator(10), MinValueValidator(1)],
        default=10,
    )
        ...

字符串
下面是我尝试for循环来尝试并获得这些总数：

# Attempts working off of: `all_albums = Album.objects.all()`

# Attempt 1
>>> for album in all_albums:
...     review_ratings_amount = album.review_set.rating.all()
...     print(review_ratings_amount)

# Attempt #2
>>> for album in all_albums:
...     review_ratings = album.review_set.filter("rating")
...     print(review_ratings)

# Attempt #3
>>> for album in all_albums:
...     review_ratings = album.review_set.get(rating)
...     print(review_ratings)

# Attempt #4
>>> for album in album_ratings:
...     review_ratings = album.review_set.get("rating")
...     for rating in review_ratings:
...             print(rating)

# Attempt 5 (this was an attempt to see if ANYTHING would return, and I actually got some QuerySets in return so I think
# this one might be in the vicinity of the right track)
>>> for album in all_albums:
...     print(album.review_set.values())

# Attempt #6
>>> for album in all_albums:
...     print(album.review_set.get('rating'))

# Attempt #7
>>> for album in all_albums:
...     items = Album.objects.all().values()
...     for item in items:
...             print(item.review_set)

# Attempt 8
>>> for album in all_albums:
...     review_ratings = Album.objects.get('review').values()
...     print(review_ratings)

# Attempt 9
>>> for album in all_albums:
...     review_ratings = Album.objects.get('review.rating')
...     print(review_ratings)

# Attempt 10
>>> for album in all_albums:
...     review_ratings = Album.objects.get('review.rating')
...     for review in review_ratings:
...             print(dict(review))

型
上面所有的尝试都返回了错误，除了# Attempt 5，它返回了album.review_set.values()中所有值的查询集--所以我认为我可能接近这段代码的“正确轨道”。
但是谁能给我一些有用的文件吗？
