Genehmigung Beziehung django_migrations verweigert mit Heroku

Question

Bei dem Versuch, Datenbankänderungen zu migrieren mit django auf Heroku, erhalte ich:

psycopg2.ProgrammingError: permission denied for relation django_migrations 

Andere Leute waren in der Lage, dieses Problem zu lösen, indem sie die entsprechenden Berechtigungen gewähren (zB Permission denied for relation) . Leider kann ich auf der Heroku-Hobby-Ebene keine Berechtigungen erteilen oder einen neuen Benutzer erstellen.

konnte ich ein paar Migrationen rückgängig zu machen, aber ich habe schließlich:

django.db.utils.ProgrammingError: table "labs_branch_tests" does not exist 

und Migration auf neuere Migrationen konnten nicht zurück.

Answer 1

ich war in der Lage, dies zu umgehen indem Sie dem Benutzer im postgres-Terminal Berechtigungen erteilen.

Zuerst mit Postgres über die Heroku CLI (heroku pg:psql) verbinden.

Dies ist klobig, aber Sie erhalten Ihren Posteingang von Heroku, indem Sie im Postgres-Terminal \c anrufen. (Die letzte Zeile der Ausgabe wird You are now connected to database DATABASE_NAME as user USERNAME sein.)

Dann Privilegien gewähren wie andere gezeigt haben:

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public to USERNAME; 
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public to USERNAME; 
GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public to USERNAME;
