Django - Redirect Unauthenticated User trying to access UpdateView to DetailView

This is my last brain cell speaking.
I have a model called Post with title, body, author, logo and pub_date fields.
There is a page in my app that the user can Update/Edit the post. I want the user to be redirected to the Post's Detail page if they tried to access it without being logged in.
The problem is that I can't reference the Post's pk to redirect the user to the related page, If I want to put it simply:
the user trying to access .../2/edit/ will be redirected to .../2/ if they aren't logged in

I Tried using LoginRequiredMixin to block the user but I can't redirect the user to the relative details page.

urls.py:

urlpatterns = [
    path('', PostListView.as_view(), name='index'),
    path('<int:pk>/', PostDetailView.as_view(), name='details'),
    path('new/', PostCreateView.as_view(), name='new_post'),
    path('<int:pk>/edit', PostUpdateView.as_view(), name='update_post'),
]

views.py:

class PostUpdateView(LoginRequiredMixin, UpdateView):
    model = Post
    login_url = reverse_lazy('details', args=[self.object.pk,]) 
    form_class = PostUpdateForm
    template_name = "posts/update_post.html"

I also tried:

class PostUpdateView(LoginRequiredMixin, UpdateView):
    def get_login_url(self) -> str:
        super().get_login_url()
        UpdateView.get(self, self.request)
        self.login_url = reverse_lazy('details', args=[self.object.pk,])
    model = Post
    form_class = PostUpdateForm
    template_name = "posts/update_post.html"

But it returns an empty/none value

Is LoginRequiredMixin even the right way to do this?
I know this can easily be achieved without GenericViews/UpdateView just by getting the request and handling it ourselves, But isn't GenericViews supposted to get the job done easier?

So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
