How to use multiple models in one template in Django?

Question

I'm developing a wiki page that's basically laid out like so:

1. Page
    Page ID
    Page name
    Has many: Categories

2. Category
    Category ID
    H2 title
    Has many: category items
    Belongs to: Page

3. Category item
    Category item ID
    H3 title
    Body text
    Image
    Belongs to: Category

What I'd like to do is when I click on a Page or a Category, to see what parts of the element are attached to it (list of categories and category items when I click on a page, for example), but as far as I've got in to my Django knowledge, this requires me to use two models on a single template.

class PageView(DetailView):
    model = Page
    template_name = 'page.html'

This is what my view part for the "View page" looks like, when I try to use two models, it crashes. What can I do to use more than one model?

I got an example in the following link: Django Pass Multiple Models to one Template

class IndexView(ListView):
context_object_name = 'home_list'    
template_name = 'contacts/index.html'
queryset = Individual.objects.all()

def get_context_data(self, **kwargs):
    context = super(IndexView, self).get_context_data(**kwargs)
    context['roles'] = Role.objects.all()
    context['venue_list'] = Venue.objects.all()
    context['festival_list'] = Festival.objects.all()
    # And so on for more models
    return context

You need to override get_context_data on your class based view: #EDIT changed period to comma after self

    def get_context_data(self, **kwargs):
        context = super(PageView, self).get_context_data(**kwargs)
        context['more_model_objects'] = YourModel.objects.all()
        return context

This will allow you to add as many context variables as you need.

Okay thank you for that answer, but now it throws out an error PageView is missing a queryset. Define PageView.model, PageView.queryset, or override PageView.get_queryset()., can you please show me some kind of a manual or smthn how to handle this, because google doesn't find that kind of an error ..

Hmm. I suspect you need to add a queryset property to your PageView class of: queryset = Page.objects.all()

Think about giving unique urls for each link used in the page. BY this you can use different views with diff models.
