Passing additional context into CBV

I'm having trouble passing some additional context into a CBV. When I pass 'userprofile' as context, it prevents any other context from successfully being passed into the view.

My view started as this:

class OrderDetail(LoginRequiredMixin, DetailView):
    model = Order

    def dispatch(self, request, *args, **kwargs):
        try: 
            user_checkout = UserCheckout.objects.get(user=self.request.user)
        except:
            user_checkout = None

        if user_checkout:
            obj = self.get_object()
            if obj.user == user_checkout and user_checkout is not None:  #checks to see if the user on the order instance ties to the user of the current request
                return super(OrderDetail, self).dispatch(request, *args, **kwargs)
            else:
                raise Http404

        else:
            raise Http404

I then tried adding this

     def get_context_data(self, *args, **kwargs):
         context = super(OrderDetail, self).get_context_data(*args, **kwargs)            
         userprofile = UserProfile.objects.get(user=self.request.user)
         context["userprofile"] = userprofile

I don't get any errors. It's just that when the page loads, none of the values that should appear (based on context) show up.

Thanks!

I think you need to add return context in your get_context_data method:

def get_context_data(self, *args, **kwargs):
     context = super(OrderDetail, self).get_context_data(*args, **kwargs)            
     userprofile = UserProfile.objects.get(user=self.request.user)
     context["userprofile"] = userprofile
     return context

Also, as your userprofile has a relation(FK or OneToOne) with User model, you can simply access them template(without passing it in context) like this:

// If OneToOne
{{ user.userprofile }}

// If FK

{{ user.userprofile_set.first }}  // using reverse relationship to fetch userprofiles

For more details, please check documentations on OneToOne, FK, Reverse Relationship.
