我的模型：

class ContentHotel(models.Model):
    hotel_id = models.IntegerField(unique=True, blank=True, primary_key=True)

    class Meta:
        managed = False
        db_table = 'content_hotels'
        ordering = ('hotel_id',)

    def __str__(self):
        return str(self.hotel_id)


class RateHotel(models.Model):
    rate_hotel_id = models.IntegerField(blank=True, primary_key=True, unique=True)
    content_hotel = models.ForeignKey(ContentHotel, on_delete=models.CASCADE, related_name='rate_hotel')

    class Meta:
        managed = False
        db_table = 'rate_hotels'
        ordering = ('rate_hotel_id',)

    def __str__(self):
        return str(self.rate_hotel_id)

我的序列化程序：

class RateHotelSerializer(serializers.ModelSerializer):

    class Meta:
        model = RateHotel
        fields = __all__


class ContentHotelSerializer(serializers.ModelSerializer):
    rate_hotel = RateHotelSerializer(many=True)

    class Meta:
        model = ContentHotel
        fields = ('hotel_id', 'rate_hotel')

    def create(self, validated_data):
        rate_hotels = …
