我有这个序列化程序:
class ReviewSerializer(serializers.ModelSerializer):
user = UserSerializer(read_only=True)
class Meta:
model = Review
fields = ('pk', 'title', 'user', 'movie', 'timestamp', 'review_text',)
我想提一下,user
并且movie
都是在模型ForeignKey
中定义的models.py
。Review
这是模型:
class Review(models.Model):
title = models.CharField(max_length=255)
user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='reviews')
movie = models.ForeignKey(Movie, on_delete=models.CASCADE, related_name='reviews')
review_text = models.TextField()
timestamp = models.DateTimeField(auto_now_add=True)
def __str__(self):
return '{movie} review by {user}'.format(user=self.user, movie=self.movie)
我想创建一个视图集,但如果我这样做:
class ReviewsViewSet(viewsets.ModelViewSet):
queryset = Movie.objects.all()
serializer_class = ReviewSerializer
并像这样注册它:
router.register(r'reviews', views.ReviewsViewSet, 'reviews')
行不通,它需要我提供movie field
此处记录的内容:
AttributeError at /api/reviews/
Got AttributeError when attempting to get a value for field `movie` on serializer `ReviewSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `Movie` instance.
Original exception text was: 'Movie' object has no attribute 'movie'.
