python - Django View with ForeignKey model -

i've got following in models.py:

class articlecategory(models.model):     category_name = models.charfield("category", max_length=200, unique=true)     slug = models.slugfield(null=true, blank=true, unique=true)      def get_data(self):         return {             "id": self.pk,             "category_name": self.category_name,             "slug": self.slug,         }  class article(models.model):     category = models.foreignkey(articlecategory)     ...      def get_data(self):         return {             "id": self.pk,             ...         } 

views.py:

def articles(request, *args, **kwargs):     context = {         'categories': articlecategory.objects.all(),         'articles': article.objects.filter(category__id=2)     }     return render(request, 'wellness.html', context) 

and works fine. however, want category__id dynamic, i'm changing function def articles(request, id, *args, **kwargs) , 'articles': article.objects.filter(category__id=id) seems working previous projects me, throws error every time try set such behavior (tried id, slug, category_name):

exception type:     typeerror exception value:    articles() takes @ least 2 arguments (1 given) exception location:     .../env/local/lib/python2.7/site-packages/django/contrib/auth/decorators.py in _wrapped_view, line 23 

maybe urls.py?

from django.contrib.auth.decorators import login_required ...  urlpatterns = [     ...     url(r'^wellness$', login_required(articles), name='wellness'),     ... ] 

yes indeed it's in urls.py.

you defined view expects 2 parameters didn't configure url function capture part of url , pass on additional parameter next request.

you want capture slug or id respectively:

slug

from django.conf.urls import url  urlpatterns = [     url(r'^wellness/(?p<slug>[-\w]+)/?$', login_required(articles), name='wellness'),     url(r'^reports/(?p<id>[0-9]+)/$', credit_views.report),# kwargs = {"id": 9} ] 

alternatively id:

urlpatterns = [     url(r'^wellness/(?p<id>[0-9]+)/$', login_required(articles), name='wellness'), ] 

in documentation can find more information.
