I have cloned master and in trying to run migrations i get this error:
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation “translation_overrides” does not exist
I see that a topic was created for this last November and seemingly fixed so i’m wondering what coudl be the cause?
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "translation_overrides" does not exist

production but getting it to run on heroku (i realise that heroku is not the ‘supported’, ‘recommended’ setup ). despite that, do you have any ideas? thanks a lot
$ ./launcher rebuild app

يحدث هذا أيضًا في تثبيت رسمي بسيط لـ discourse_docker، باستخدام اختبار استعادة آلي عبر خط الأنابيب كل صباح من أيام الأسبوع. ظهر خطأ مشابه فجأة في خط الأنابيب الفاشل.

كان السبب الجذري عدم تطابق الإصدار بين النسخة الاحتياطية المستعادة وكود الحاوية.
يحتوي أحدث كود لـ Discourse على نموذج يشير إلى جدول translation_overrides، لكن قاعدة بيانات الإنتاج (من النسخة الاحتياطية) تعمل على إصدار أقدم حيث إما أن هذا الجدول غير موجود بعد أو له اسم مختلف.
ما نجح معي هو إعادة البناء أولاً (مما ينشئ المخطط من الصفر)، ثم استعادة النسخة الاحتياطية. تستخدم عملية الاستعادة آلية الاستعادة المدمجة في Discourse، والتي تقوم بحذف قاعدة البيانات وإعادة إنشائها بشكل صحيح.
