I have a ListView but when I call it only the get_context_data method works (the news and category model, not the product) when I try to display the information of the models in the templates.
view:
JavaScript

class HomeView(ListView):2
model = Product3
context_object_name='products'4
template_name = 'main/home.html'5
paginate_by = 256
7
def get_context_data(self, **kwargs):8
categories = Category.objects.all()9
news = News.objects.all()10
context = {11
'categories' : categories,12
'news' : news,13
}14
context = super().get_context_data(**kwargs)15
return context16
There is also this piece of code: context = super().get_context_data(**kwargs) If it’s written before: categories = Category.objects.all() The Product model is show but not the others.

The problem is that you override context, but you need to update it. Try this:
JavaScript

def get_context_data(self, **kwargs):2
context = super().get_context_data(**kwargs)3
categories = Category.objects.all()4
news = News.objects.all()5
context.update({6
'categories' : categories,7
'news' : news,8
})9

return context11
