Zugriff auf image_thumb

mgraf

Hallo,
kann mir bitte jemand erklären warum folgender Abschnitt nicht funktioniert?

Code

security.declareProtected(View, 'Image2Base64')
    def Image2Base64(self):
        if self.getImage():
            encImg = self.image_thumb.data.encode('base-64')
            # indent the data block:
            indentVar = '\n  '.join(encImg.strip().split('\n'))
            return indentedVar
        return None

Folgender Traceback kommt:

Code

AttributeError: image_thumb

Alles anzeigen

Wenn ich image_thumb direkt im Browser aufrufe, wird mir das Bild angezeigt..

Vielleicht hat jemand von Euch eine Hilfestellung, bitte.

Danke & lg
