En la última versión de Discourse en Docker, estoy experimentando el inverso de este problema: Polls disabled caused 500 error

Si las encuestas están activadas, responder a un tema muestra un error 500. Rastreo:

NoMethodError en PostsController#create

Hola Ben, parece que te faltan algunas migraciones de base de datos del plugin de encuestas. ¿Podrías contarnos más sobre cómo tienes configurado Discourse? ¿Siguiiste nuestra guía de instalación estándar?

6

Una solución sencilla aquí es:

cd /var/discourse
./launcher rebuild app

Mi suposición es que, de alguna manera, las migraciones no se ejecutaron correctamente cuando realizaste una actualización o restauración.

Hola a todos, estoy desarrollando un plugin, así que opté por la ruta de discourse_docker. De hecho, ya envié un PR con las instrucciones allí. Hay algunos pasos adicionales que faltan si deseas profundizar más. Ya estoy funcionando con el plugin de encuestas desactivado; esto no afecta mis pruebas.
