SiverStripe 3: Die Methode 'Fortemplate' existiert nicht in 'Datei'

Question

Ich erstelle eine GridField für meine Seite mit einer has_many Beziehung zu meiner DataObjects aber nach dem Hinzufügen von Daten und Speichern des Objekts bricht es die Seite im CMS. Ich kann nicht herausfinden warum oder irgendwelche Antworten nach dem Suchen finden. Hier ist der Fehler und mein Code:

[User Error] Uncaught Exception: Object->__call(): the method 'fortemplate' does not exist on 'File'

Answer 1

Das Problem ist diese Zeile:

public static $summary_fields = array(
    // ... 
    'FirmwDownloadFile' =>'Firmware Download File' 
); 

Dies wird versuchen, die FirmwDownloadFile in der GridField anzuzeigen, aber FirmwDownloadFile ist eine File. GridField kann nicht File anzeigen.

Was wir tun können, ist eine Variable File angezeigt wie die File.Name in unserem summary_fields:

private static $summary_fields = array(
    // ... 
    'FirmwDownloadFile.Name' 
); 

private static $field_labels = array(
    // ... 
    'FirmwDownloadFile.Name' =>'Firmware Download File' 
);
