如何将多对多字段序列化为列表,然后通过rest框架返回它们?在下面的示例中,我尝试返回该帖子以及与其关联的标签列表。
models.py
class post(models.Model):
tag = models.ManyToManyField(Tag)
text = models.CharField(max_length=100)
serializers.py
class PostSerializer(serializers.ModelSerializer):
class Meta:
model = Post
fields = ("text", "tag"??)
views.py
class PostViewSet(viewsets.ReadOnlyModelViewSet):
queryset = Post.objects.all()
serializer_class = PostSerializer
