I am new to DJango and still understanding how views and urls work. I am trying to show a list of categories in my side bar as well as get bread crumbs to work. I cannot get the breadcrumbs to show correctly unless I go to mysite/category/categoryItem/sub_categoryItem but then I cannot get it to pull up the post even though it list it in the list. It is just a blank page. This at least tells me that the template is pulling the sidebar data.
views.py
def show_category(request,hierarchy= None):
category_slug = hierarchy.split('/')
category_queryset = list(Category.objects.all())
all_slugs = [ x.slug for x in category_queryset ]
parent = None
for slug in category_slug:
if slug in all_slugs:
parent = get_object_or_404(Category,slug=slug,parent=parent)
else:
instance = get_object_or_404(Post, slug=slug)
breadcrumbs_link = instance.get_cat_list()
category_name = [' '.join(i.split('/')[-1].split('-')) for i in breadcrumbs_link]
breadcrumbs = zip(breadcrumbs_link, category_name)
return render(request, "wiki/post_detail.html", {'instance':instance,'breadcrumbs':breadcrumbs})
return render(request,"sidebar.html",{'post_set':parent.post_set.all(),'sub_categories':parent.children.all()})
def post_detail(request,slug=None):
post = get_object_or_404(Post,slug=slug)
return render(request,"wiki/post_detail.html",{ 'post':post})
def post_list(request, slug=None):
posts = Post.objects.all()
return render(request,"wiki/postlist.html",{ 'posts':posts})`enter code here`
urls.py
urlpatterns = [
url(r'^wiki/$', views.post_list , name='wiki'),
url(r'^(?P<slug>[\w-]+)/$', views.post_detail, name="postdetail"),
url(r'^category/(?P<hierarchy>.+)/$', views.show_category, name='category'),
]
