Python Django-ical依恋原因'；HttpResponse'；对象没有属性'；编码'；

当我将ics日历邀请附加到Django中发送的电子邮件时，我得到了AttributeError:“HttpResponse”对象没有属性“encode”。这只是如果我附加了ical邀请，如果我不附加，一切都很好

我不知道它为什么要在HttpResponse对象上查找encode属性，或者如何处理它

    recip = [user_assigned]

    email.attach(ics_form['Filename'], ics_form, 'text/calendar')
    email.send()

您尚未粘贴所有代码，但听起来您正在执行以下操作：

ical = create_ics(thedata)
email_invite(ical, theuser)

def email_invite(filename, ics, user_assigned):
    subject = 'You Have Been Assigned Schuduled Maintance/Calendar invite'
    from_address = 'foo@no-reply.com'
    body = "This is a invite"
    recip = [user_assigned]
    email = EmailMessage(subject, body, from_address, recip)
    email.attach(filename, ics, 'text/calendar')
    email.send()

def create_ics(data):
    start1 = data['date_due']

    return response

ical = create_ics(thedata)

这会引发您看到的异常，因为

ics\u form

是一个

HttpResponse

对象。。。

attach

方法希望文件的内容作为字符串附加

也许您应该让

create_ics

函数返回ical内容，并在单独的视图函数中返回HttpResponse。比如：
