简单的说，将WineSerializer作为一个字段加以解决。

  class BottleSerializer（serializers.HyperlinkedModelSerializer）：
 wine = WineSerializer（source ='wine'）

 class Meta：
 model = Bottle 
 fields =（'url'，'wine'，'user'，'date_rated'，'rating'，'comment'，'get_more' b $ b  

with：

  class WineSerializer（serializers.HyperlinkedModelSerializer）：

 class Meta：
 model = Wine 
 fields =（'id'，'url'，'color'国家'，'区域'，'名称'）
 

感谢您的帮助@mariodev： p>

I'm trying to return a HttpResponse from Django Rest Framework including data from 2 linked models. The models are:

class Wine(models.Model):

    color = models.CharField(max_length=100, blank=True)
    country = models.CharField(max_length=100, blank=True)
    region = models.CharField(max_length=100, blank=True)
    appellation = models.CharField(max_length=100, blank=True)

class Bottle(models.Model):

    wine = models.ForeignKey(Wine, null=False)
    user = models.ForeignKey(User, null=False, related_name='bottles')

I'd like to have a serializer for the Bottle model which includes information from the related Wine.

I tried:

class BottleSerializer(serializers.HyperlinkedModelSerializer):
    wine = serializers.RelatedField(source='wine')

    class Meta:
        model = Bottle
        fields = ('url', 'wine.color', 'wine.country', 'user', 'date_rated', 'rating', 'comment', 'get_more')

which doesn't work.

Any ideas how I could do that?

Thanks :)

Simple as that, adding the WineSerializer as a field solved it.

class BottleSerializer(serializers.HyperlinkedModelSerializer):
    wine = WineSerializer(source='wine')

    class Meta:
        model = Bottle
        fields = ('url', 'wine', 'user', 'date_rated', 'rating', 'comment', 'get_more')

with:

class WineSerializer(serializers.HyperlinkedModelSerializer):

    class Meta:
        model = Wine
        fields = ('id', 'url', 'color', 'country', 'region', 'appellation')

Thanks for the help @mariodev :)
