Il plugin Polls causa un errore 500 al salvataggio del post

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

Ciao Ben, sembra che manchino alcune migrazioni del database dal plugin dei sondaggi. Puoi dirci di più su come hai configurato Discourse? Hai seguito la nostra guida standard di installazione?

6

Una semplice soluzione alternativa è:

cd /var/discourse
./launcher rebuild app

Il mio sospetto è che, in qualche modo, le migrazioni non siano state eseguite correttamente durante un aggiornamento o un ripristino.

Ciao a tutti, sto sviluppando un plugin, quindi ho scelto la strada di discourse_docker. Ho infatti inviato una PR con le istruzioni lì. Ci sono alcuni altri passaggi mancanti se volete approfondire. Ora è attivo e funzionante con il plugin polls disabilitato: non influisce sui miei test.
