            return redirect('Blogs:Blog_detail', slug=instance.slug)
        return redirect('reports:Blog_report', slug=instance.slug, year=year)

Side note: Only the process to get your instance should be in get_object. It should also be returned as the properly named values on self, that is self.object and self.blog in this case. Everything else still belongs in get_context_data.
Review the docs at Single object mixins | Django documentation | Django along with the detailed information about DetailView at DetailView -- Classy CBV. You want to become more familiar with the flow of events through the CBVs.

What makes you think that the solution for your update view is fundamentally any different than your previous solution? (Hint: It’s not. You need to address the same issues here as you handled previously.)

25

you mean?

from urllib.parse import unquote

for me didn’t work in classed based view
i don’t know why, i may need to fine a good code mentor.

26

That’s just importing the library.

You still need to use that library to translate the submitted slug, in the same way you unqote the arg in your other view.

27

i did try


    def get_object(self, queryset=None):
        slug = unquote(self.kwargs.get('slug'))
        return get_object_or_404(Blog, slug=slug, user=self.request.user)

and


    def get_object(self, queryset=None):
        slug = self.kwargs.get('slug')
        return get_object_or_404(Blog, slug=unquote(slug), user=self.request.user)

but nothing…

28

Again as above,

  • Did you visually verify what you’re getting as self.kwarg.get('slug'),
  • Did you verify what you get after the unquote function`?
  • Did you check to verify that that slug exists in the database for the current user?
    • Since the slug in this case should be unique, do you really need the additional user attribute in the query?

Debugging something like this involves working this through step-by-step, ensuring that everything is happening as it should at each step of the process.

Using the Django shell is very useful for checking out things like this.
