Django Rest Framework, hyperlinking a nested relationship

Question

I\'ve got two models: User and Ticket. Ticket has one User, User has many Tickets

Answer 1

For the record, here is an example of the full solution based on Joe Holloway's answer:

from rest_framework.reverse import reverse

class WorkProjectSerializer(serializers.CustomSerializer):
   issues = drf_serializers.SerializerMethodField()

    def get_issues(self, obj):
        request = self.context.get('request')
        return request.build_absolute_uri(reverse('project-issue-list', kwargs={'project_id': obj.id}))

    class Meta:
        model = WorkProject
        fields = '__all__'

Answer 2

You can use a SerializerMethodField to customize it. Something like this:

class UserSerializer(serializers.HyperlinkedModelSerializer):
    tickets = serializers.SerializerMethodField('get_tickets')

    def get_tickets(self, obj):
        return "http://127.0.0.1:8000/users/%d/tickets" % obj.id

    class Meta:
        model = MyUser
        fields = ('id', 'nickname', 'email', 'tickets')

I hard-wired the URL in there for brevity, but you can do a reverse lookup just as well. This basically just tells it to call the get_tickets method instead of the default behavior in the superclass.
