Django Rest Framework - Get related model field in serializer

Question

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 :)

Answer 1

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 :)
