Polls-Plugin verursacht 500-Fehler beim Speichern des Beitrags

On the latest version of Discourse on Docker I’m having the reverse of this issue: Polls disabled caused 500 error

If polls are enabled replying to a topic shows a 500 error. Trace:

NoMethodError in PostsController#create

undefined method `polls' for #<Post:0x00007fa2b3502050>

Hallo Ben, es scheint, als fehlten dir einige Datenbank-Migrationen aus dem Umfragen-Plugin. Könntest du uns mehr darüber erzählen, wie du Discourse eingerichtet hast? Hast du unseren Standard-Installationsleitfaden befolgt?

Ein einfacher Workaround hierfür ist:

cd /var/discourse
./launcher rebuild app

Meine Vermutung ist, dass Migrationen beim Upgrade oder der Wiederherstellung irgendwie nicht korrekt ausgeführt wurden.

Hey Leute, ich entwickle gerade ein Plugin und habe mich für den discourse_docker-Weg entschieden. Ich habe dort übrigens einen PR mit den Anweisungen eingereicht. Es fehlen noch ein paar weitere Schritte, falls ihr diese genauer erläutern möchtet. Aktuell läuft alles mit dem Polls-Plugin deaktiviert – das hat keinen Einfluss auf meine Tests.
