错误，因为对象属性不存在，但它确实存在

Question

我正在尝试使用sendgridpythonapi发送电子邮件。为此，我使用以下函数：

def send_contact_us_email(sender=None, name=None, subject=None, message=None):
status_code = None
if sender and name and subject and message:
    to = "test@test.com"
    email = Email.objects.create(to=to, sender=sender, subject=subject, content=message)
    status_code = email.send()

return status_code

所以我使用一个电子邮件模型来存储电子邮件，以备以后参考，这样发送电子邮件的代码可以放在模型中。以下是电子邮件模型：

^{pr2}$

当我运行这段代码时，我希望它能正常工作；我用发送电子邮件所需的所有数据创建一个email模型对象，然后使用sendgrid helper类构造一个JSON请求主体，供sendgridapi处理。在

但是，我得到了以下错误：

Email object has no attribute get

但是，当我查看sendgrid helper类时，email类确实有一个get属性：

def get(self):
    """
    Get a JSON-ready representation of this Email.

    :returns: This Email, ready for use in a request body.
    :rtype: dict
    """
    email = {}
    if self.name is not None:
        email["name"] = self.name

    if self.email is not None:
        email["email"] = self.email
    return email

因此，我无法解决这个错误，我遗漏了什么？在

Answer 1

当我写邮件的时候(自我发送者)而且，它使用的是我的模型，而不是sendgrid编写的helper Email类。所以只需从sendgrid导入Email或其他内容。在

from sendgrid.helpers.mail import Email as Emaill
