Ajouter des commentaires à l'article django createview foreignkey

Question

Je voudrais ajouter des commentaires à mon article en utilisant django createview. En ce moment, je peux ajouter des articles sans problème. Je peux ajouter des commentaires. Mais je ne peux pas ajouter les commentaires aux bons articles.

Cela fait deux jours que je suis à ce poste. Je voudrais vraiment faire ça avec cbv, car j'essaie d'apprendre. Toute aide pour expliquer ce que je fais de mal et comment le corriger serait très appréciée.
