python - Django REST framework - HyperlinkedRelatedField with additional parameter -

-

i'm building rest web api django rest framework. have many-to-many relation between categories , wallets. starting category retrieve wallets linked to, , shell works fine

models:

class wallet(models.model):     nome = models.charfield(max_length=255)     creato = models.datetimefield(auto_now=false)     utente = models.foreignkey(user)     wallettype = models.foreignkey(wallettype)     payway = models.manytomanyfield(payway, through = 'wpw', blank = true)     defaultpayway = models.foreignkey('wpw', related_name = 'def_pw', null = true)      def __unicode__(self):         return self.nome  class category(models.model):     nome = models.charfield(max_length=255)     creato = models.datetimefield(auto_now=false)     enus = models.foreignkey(enus)     wallet = models.manytomanyfield(wallet)     utente = models.foreignkey(user)     owner = models.manytomanyfield(user, related_name='owner_cat')

urls:

urlpatterns = patterns(     '',     url(r'^$', views.cat_list.as_view()),     url(r'^/(?p<pk>[0-9]+)/*$', views.cat_detail.as_view()),     url(r'^/(?p<cat_id>[0-9]+)/wallets/*$', views.cwallet_list.as_view()),     url(r'^/(?p<cat_id>[0-9]+)/wallets/(?p<pk>[0-9]+)/*$', views.cwallet_detail.as_view(), name='cwallet-detail'), )

serializer:

class cat_serializer(serializers.modelserializer):     wallet = serializers.hyperlinkedrelatedfield(         many=true,         read_only=true,         view_name='cwallet-detail',         # lookup_field = 'pk',         # lookup_url_kwarg = 'pk'     )     subcat_count = serializers.integerfield(         source='subcategory_set.count',         read_only=true     )      class meta:         model = category         fields = ('id', 'nome','wallet','subcat_count')

when call:

get http://localhost:8000/categories/77/wallets

i retrieve:

{     'nome': 'dinner',     'subcat_count': 12,     'wallet': {         'http://localhost:8000/77/wallet/1',         'http://localhost:8000/77/wallet/2',         'http://localhost:8000/77/wallet/3',     } }

but doesn't work , error:
"could not resolve url hyperlinked relationship using view name "cwallet-detail". may have failed include related model in api, or incorrectly configured lookup_field attribute on field."

i think problem linked additional param: in fact in urls.py have pk wallet id , cat_id category id. can't figure how pass category id 'cwallet-detail'.

anyone know how pass second paramater hyperlinkedrelatedfield?
thank in advance.

after reading docs , posting new issue on tom christie's django rest github, know it's not officially supported, doumentations , patch work in progress.

actually there this link building custom hyperlinked filed solve problem.

hope has same problem.
