Erreur lors de l'activation des réponses imbriquées et du vote sur les publications

cuo_wu · Mai 23, 2026, 2:15

Lorsque j’active les réponses imbriquées et le vote sur les messages, puis que je convertis un message en vue à réponses imbriquées, j’obtiens une erreur 500.

Il est probable que les réponses imbriquées et les votes de messages ne soient pas compatibles (pour l’instant)

markvanlan · Mai 26, 2026, 1:11

Oui — je pense que la meilleure solution pour l’instant est d’ajouter quelques vérifications dans le plugin de vote sur les messages pour ignorer la logique lorsque les réponses imbriquées sont activées pour un sujet. En gros, rendre explicitement le plugin incompatible avec les réponses imbriquées.

Ce serait aussi cool d’avoir un mode « convertir en réponses imbriquées » pour le vote sur les messages. Je suppose qu’une certaine proportion d’utilisateurs du vote sur les messages aimeraient simplement basculer vers les réponses imbriquées.

Avez-vous vu cela ?

FIX: post-voting topics failed to load in nested view (#40187)

opened 08:10AM - 20 May 26 UTC

When posting a post-voting topic using `discourse-post-voting` plugin, and openi…ng it in nested view, the page render failed. In devcontainer, the page throw an unrecoverable render error. And in production, the server returned 500 error. This issue stems from the `shouldRender` reading `topicPageQueryParams` unguarded, in nested view, the connector failed. This commit solved this by adding a guard to that. Also add some specs to avoid regression. Before: <img width="1917" height="912" alt="image" src="https://github.com/user-attachments/assets/1ebb901f-a3c6-43a5-8a72-76cb7bae13be" /> After: <img width="1917" height="926" alt="image" src="https://github.com/user-attachments/assets/a35ef924-5481-475b-8ca1-88557fe437b6" /> Also solved an issue preventing the textarea triggered by clicking `Add a comment` button from focusing in nested view.

Je n’avais pas, non ! Je préfère toujours l’idée de désactiver les votes sur les réponses imbriquées, car c’est très similaire et cela évitera d’autres problèmes de compatibilité

small-lovely-cat · Mai 26, 2026, 9:29

Il semble y avoir une fonction similaire…

Mais le vote après publication a pour fonction d’accepter ou de rejeter un message. Les utilisateurs pourraient se sentir déstabilisés s’ils utilisent par défaut une vue imbriquée et ouvrent un sujet de vote après publication, pour découvrir qu’ils ne peuvent pas voter, alors que ceux en vue plate le peuvent.

Peut-être que l’ajout d’un support serait une meilleure idée ? Je ne suis pas tout à fait certain de cela.

markvanlan · Mai 27, 2026, 1:22

Pour l’instant, je vais le désactiver pour les réponses imbriquées. À l’avenir, nous pourrions envisager d’intégrer directement une fonction de vote positif/négatif dans les réponses imbriquées, afin qu’elle constitue un remplacement plus efficace et plus direct du vote sur les publications.

cuo_wu · Mai 27, 2026, 3:25

C’est une meilleure approche : ajouter une fonction de vote dans les réponses imbriquées, ce qui rend le tri par les plus populaires encore plus pertinent.

cuo_wu · Mai 27, 2026, 3:34

Oui, en réalité, qu’il s’agisse de réponses imbriquées ou non, une fonction de vote devrait être présente. J’ai apporté quelques modifications aux votes de publication et à la vue imbriquée.
