Subject: [PATCH] fix: Use string references for foreign_keys in SQLAlchemy
 relationships
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

foreign_keys muss als String angegeben werden, nicht als Attribut-Referenz,
da die Attribute zur Definition-Zeit noch nicht verfügbar sind.
