Я попытался напечатать простой образ QR-кода, и я не смог его получить. Я использовал code that I found in the documentation, и это не сработало. Нужно ли мне что-нибудь еще? У меня установлена библиотека reportlabs.QR-код не отображается в отчете. Зачем?
<img t-att-src="'/report/barcode/QR/%s' % 'My text in qr code'" />
<img t-att-src="'/report/barcode/?type=%s&value=%s&width=%s&height=%s'%('QR', 'text', 200, 200)"/>
Я проверил лог-файл, и я нахожу эту ошибку:
