Hello!
I am encountering the error "Reverse for 'article' not found. 'article' is not a valid view function or pattern name" when trying to edit an article. Although the article updates correctly, clicking the “edit” button triggers this error.

Below are the relevant code snippets from my project:

</div>

{% endblock main %}

The error likely arises because in the Article model's get_absolute_url method, I'm using reverse('article', kwargs={'pk': self.pk}), but in urls.py the corresponding URL pattern is named 'article-view'.

I would appreciate advice on how to resolve this mismatch to prevent the reverse error.
