Fails with custom lookup_field

[hroncok]

I have the following setup:

# Course model has sport as related filed to Sport model with it's ID

# serializers.py:
from drf_hal_json import serializers

class SportSerializer(serializers.HalModelSerializer):
    class Meta:
        model = models.Sport
        fields = ('shortcut',)

class CourseSerializer(serializers.HalModelSerializer):
    class Meta:
        model = models.Course
        fields = ('sport',)

# views.py:
class SportViewSet(*base):
    queryset = models.Sport.objects.all()
    serializer_class = serializers.SportSerializer

class CourseViewSet(*base):
    queryset = models.Course.objects.all()
    serializer_class = serializers.CourseSerializer

Now it all works fine but I want to use custom lookup_field on sports:

# Course model has sport as related filed to Sport model with it's ID

# serializers.py:
class SportSerializer(serializers.HalModelSerializer):
    url = serializers.HyperlinkedIdentityField(
         read_only=True, view_name='sport-detail', lookup_field='shortcut')
    # ...

class CourseSerializer(serializers.HalModelSerializer):
    sport = serializers.HyperlinkedRelatedField(
         read_only=True, view_name='sport-detail', lookup_field='shortcut')
    # ...

# views.py:
class SportViewSet(*base):
    # ...
    lookup_field = 'shortcut'

It doesn't work, resulting in exception:

Could not resolve URL for hyperlinked relationship using view name "sport-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field.

But when I use HyperlinkedModelSerializer from DRF, it works fine, so I suspect the problem is in HalModelSerializer.

I don't really understand HalModelSerializer's code, but it seems it completely redefines the fields, thus the information I provided within HyperlinkedRelatedField constructor gets lost.

I tried to set view_name='balahblah-detail' just to see what happens and the exception still talks about sport-detail which I think backs up my thought.

BTW see this commit and the code there hroncok/utvsapi-django@8e9f793 for complete code example.

And thanks for drf-hal-json.

Hi I'm trying to get drf-hal-json working, and I get the same issue.
serializers.ModelSerializer acts ok , data is retrieved with pagination
but as soon as I use the HalModelSerializer I get this same issue.
any Idea How to fix this?
