Ich habe jeden Thread in Bezug auf diesen Fehler gelesen und ich kann nicht herausfinden, woher das kommt.Array zu String-Konvertierung ArrayChoiceList
Ich habe ein Formular mit vielen Kontrollkästchen Felder, die von Arrays gefüllt werden. In meiner Entity konvertiere ich jedoch alle Felder in eine durch Komma getrennte Zeichenfolge (ja, ich weiß, das ist hässlich) und die fraglichen Felder funktionieren alle gut, aber ich bekomme diesen Fehler und ich kann einfach nicht herausfinden, wo das Problem liegt kommt aus. Als ich diese Felder debugging gab es mir die Arrays, die in Frage waren und ich konnte sie beheben
Ich habe auch noch 4 weitere EntityType Auswahllisten, die aus 4 anderen Datenbanktabellen auffüllen. Alle Daten ziehen und funktionieren ordnungsgemäß für alle Entitäten, aber wenn ich versuche, die Datenbank persistent zu machen, bekomme ich diesen Fehler, aber ich kann keinen Verweis darauf finden, auf welche Entity oder Array/Feld sich dies bezieht. Alles was ich unten sehe sind leere Arrays.
Wenn ich meine Entity und FormType sehe, kann ich diese veröffentlichen.
