Django URL page parameter and another parameter -

how can fix this? in template have this:

<a href="{% url 'hp:category-filtered-page-blog' category=category page=page_obj.next_page_number %}">next</a> 

i pagination url parameter. cbv:

class categoryfilteredbloglist(listview):     template_name = 'blog.html'     context_object_name = 'posts'     paginate_by = 1     allow_empty = true      def dispatch(self, *args, **kwargs):         log_visitor(self.request, 'blog sort on category: {0}'.format(self.kwargs['category']))         return super(categoryfilteredbloglist, self).dispatch(*args, **kwargs)      def get_queryset(self):         print(self.kwargs['category'])         self.category = get_object_or_404(category, title=self.kwargs['category'])         return post.objects.filter(category__title__contains=self.category).order_by('-id')      def get_context_data(self, **kwargs):         context = super(categoryfilteredbloglist, self).get_context_data(**kwargs)         context['category'] = self.category         return context 

my url config:

url(r'^blog/category/(?p<category>.+)$', categoryfilteredbloglist.as_view(), name='category-filtered-blog'), url(r'^blog/category/(?p<category>.+)/page/(?p<page>\w+)$', categoryfilteredbloglist.as_view(), name='category-filtered-page-blog'), 

it prints: 'stuff/page/2' 'stuff'.

the problem first url pattern matching including slash itself:

url(r'^blog/category/(?p<category>.+)$', categoryfilteredbloglist.as_view(), name='category-filtered-blog'), 

demo of happening:

>>> import re >>> pattern = re.compile('^blog/category/(?p<category>.+)$') >>> pattern.match('blog/category/stuff/page/2').group(1) 'stuff/page/2' 

to fix it, remove first url pattern , let second 1 capture category.

demo:

>>> pattern = re.compile('^blog/category/(?p<category>.+)/page/(?p<page>\w+)$') >>> pattern.match('blog/category/stuff/page/2').group(1) 'stuff' 

if want page optional , allow urls blog/category/stuff work, can swap urls first check page there:

url(r'^blog/category/(?p<category>.+)/page/(?p<page>\w+)$', categoryfilteredbloglist.as_view(), name='category-filtered-page-blog'), url(r'^blog/category/(?p<category>.+)$', categoryfilteredbloglist.as_view(), name='category-filtered-blog'),
