Je rencontre le problème suivant en essayant de reconstruire Discourse avec le plugin de vote :

```plaintext
NameError: constante non initialisée SiteCategorySerializer

```

Cela semble lié à un récent remaniement dans le plugin :

- [FIX: wraps overrides in reloadable\_patch · discourse/discourse-topic-voting@020ed3c · GitHub](https://github.com/discourse/discourse-voting/commit/020ed3cd6d19d6bca92b7273ac6cdde2ac5eefe4#diff-b61ae67bc6a57a3decb8d15b832077f4)
- [FIX: Add can\_vote attribute to all category serializers. (#43) · discourse/discourse-topic-voting@7e6f27b · GitHub](https://github.com/discourse/discourse-voting/commit/7e6f27b198416a6ef27f0f0df715f5e6cfc00197#diff-b61ae67bc6a57a3decb8d15b832077f4)

La dernière version « fonctionnelle » que j’ai testée est la suivante :

- [PERF: avoid N+1 on category load · discourse/discourse-topic-voting@9b4f233 · GitHub](https://github.com/discourse/discourse-voting/commit/9b4f233b9d33a946f626597aaf3863d2305b8809#diff-b61ae67bc6a57a3decb8d15b832077f4)

J’utilise la version 2.3.2 de Discourse.
