Ich erhalte TransactionManagementError, wenn ich versuche, eine Django-Benutzermodellinstanz zu speichern, und in ihrem post_save-Signal speichere ich einige Modelle, die den Benutzer als Fremdschlüssel haben.
Der Kontext und Fehler ist dieser Frage ziemlich ähnlich. Django TransactionManagementError bei der Verwendung von Signalen
In diesem Fall tritt der Fehler jedoch nur beim Testen der Einheit auf .
Es funktioniert gut beim manuellen Testen, aber Unit-Tests schlagen fehl.
Fehlt mir etwas?
