[FIXED] DeleteView is missing a queryset

Issue

So i'm working on an inventory app, a django-app where you can handle inventory in a company. I've been using mostly class-based so far in my views.py, and i can already create and edit all of my models using class-based views.

So when it comes to the generic.DeleteView, i have some problems.

This is my function in views.py:

class DeleteItemView(DeleteView):
    model: Item
    success_url: reverse_lazy('inventory_app:items')
    template_name = 'inventory/detail_pages/item_detail.html'

And this is my URL to the function:

path('items/<int:pk>/delete/', views.DeleteItemView.as_view(), name='delete_item')

When i call this url with a button, this error appears:

DeleteItemView is missing a QuerySet. Define DeleteItemView.model, DeleteItemView.queryset, or override DeleteItemView.get_queryset().

So i heard online that this appears when /<int:pk>/ is missing in the url. But i have it in mine, so whats the problem here?

Thank you already

Solution

class DeleteItemView(DeleteView):
    model = Item
    success_url = reverse_lazy('inventory_app:items')
    template_name = 'inventory/detail_pages/item_detail.html'

remove the colon (:) and change to =
