Python/Django：使用xhtml2pdf将html呈现为pdf时获取AttributeError

你可以看到我犯的错误

我正在尝试使用Django从html模板呈现pdf。 当我摆弄它时，它在本地运行得相当好。 设法从中获取.pdf文件

现在我陷入了这个错误，声称uri没有属性编码。 有没有人在使用这个python包时出现过类似的错误？如果是这样，您是如何修复的

from __future__ import print_function
import easy_pdf
from deliveries.models import Delivery
from django.conf import settings
from easy_pdf.views import PDFTemplateView
import os
import sys
from django.core.wsgi import get_wsgi_application
from scripts import messages as msg

basename = os.path.splitext(os.path.basename(__file__))[0]

def run(*args, **kwargs):
    if len(args) < 1 or args[0] is None:
        print(msg.GeneralMessages.ERROR_DELIVERY_MISSING, file=sys.stderr)
        sys.exit(1)

    if not str(args[0]).isdigit():
        logger.error(msg.GeneralMessages.ERROR_DELIVERY_INVALID)
        sys.exit(1)

    delivery = Delivery.get(args[0])
    application = get_wsgi_application()
    context = ''
    view = ''
    encoding = 'utf-8'
    print(context)
    view = easy_pdf.rendering.render_to_pdf('report.html', context)
    if view:
        f = open('report.pdf', 'wb')
        f.write(view)
        f.close()
        print ('Report has been exported as .pdf')

if not settings.configured:
    settings.configure(
        DEBUG=True,
        TIMEZONE="UTC",
        INSTALLED_APPS=["easy_pdf", "django.contrib.staticfiles"],
