Django Rest Framework NoReverseMatch не является допустимой функцией представления или именем шаблона

Сначала некоторый контекст :

Класс моделей :

class Property(models.Model, AbstractUsagesLinked, AbstractErrorsFinder, InsurableMixin):
    type = models.ForeignKey(PropertyType, verbose_name=_('type de lot'), null=True, blank=True, related_name='properties_set', on_delete=models.CASCADE)
    # other fields

Класс Сериализаторы :

class PropertySerializer(serializers.HyperlinkedModelSerializer, FlexFieldsModelSerializer):
    type = serializers.HyperlinkedRelatedField(view_name="api:propertytype-detail", read_only=True)  # add hyperlink reference
     # others fields

    class Meta:
        model = Property
        fields = [field.name for field in model._meta.fields]
        expandable_fields = {
            'type': (PropertyTypeSerializer, {'many': False}),
            # others fields

        }

class PropertyTypeSerializer(serializers.HyperlinkedModelSerializer, FlexFieldsModelSerializer):
    class Meta:
        model = PropertyType
        fields = [field.name for field in model._meta.fields]

Виды класса :

@permission_classes((Check_API_KEY_Auth, ))
class PropertyDetail(RetrieveAPIView):
    queryset = Property.objects.all()
    serializer_class = PropertySerializer
    pagination_class = CustomPagination

@permission_classes((Check_API_KEY_Auth, ))
class PropertyTypeDetail(RetrieveAPIView):
    queryset = PropertyType.objects.all()
    serializer_class = PropertyTypeSerializer
    pagination_class = CustomPagination

Урлы :

api.urls.py :

urlpatterns = [
    # lots of path
    path('property/', views.PropertyList.as_view(), name="property-list"),
    path('property/<int:pk>/', views.PropertyDetail.as_view(), name="property-detail"),
    path('propertytype/', views.PropertyTypeList.as_view(), name="propertytype-list"),
    path('propertytype/<int:pk>/', views.PropertyTypeDetail.as_view(), name="propertytype-detail"),

main.urls.py :

urlpatterns = [ # lots of path
    url(r'^api/', include((api.urls, 'api'), namespace='api')),
]

Когда я запрашиваю свойство, я получаю :

django.urls.exceptions.NoReverseMatch: Reverse for 'propertytype-detail' not found. 'propertytype-detail' is not a valid view function or pattern name.
django.core.exceptions.ImproperlyConfigured: Could not resolve URL for hyperlinked relationship using view name "propertytype-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

Только исключения происходят на некоторых свойствах id и не на всех свойствах, я не могу найти почему.
