我的数据库中有文件url。我想将文件作为附件发送到电子邮件中。我已经尝试了以下代码

I have the file url in my db. I want to send the file as an attachment in email. I have tried the below code

def mail_business_plan(sender, instance, created, **kwargs): if created: ctx = {"ctx":instance} from_email = 'info@some_email.in' subject = 'Business Plan by' + instancepany_name message = get_template('email/business_team.html').render(ctx) to = ['some_email@gmail'] mail = EmailMessage(subject, message, to=to, from_email=from_email) mail.attach_file(instance.presentation, instance.presentation.read(), instance.presentation.content_type) return mail.send()

我收到错误，因为 AttributeError：'FieldFile'对象没有属性'content_type'

I am getting error as "AttributeError: 'FieldFile' object has no attribute 'content_type'"

如果文件路径存储在数据库中，发送带有附件的邮件的最佳方法是什么。

What's the best way to send mail with attachment, if the file path is stored in the database.

推荐答案

假设您有一个模型，

Assuming you have a model as,

class MyModel(models.Model): # other fields presentation = models.FileField(upload_to='some/place/')

并在您的信号中，

import mimetypes def mail_business_plan(sender, instance, created, **kwargs): if created: ctx = {"ctx": instance} from_email = 'info@some_email.in' subject = 'Business Plan by' + instancepany_name message = get_template('email/business_team.html').render(ctx) to = ['some_email@gmail'] mail = EmailMessage(subject, message, to=to, from_email=from_email) content_type = mimetypes.guess_type(instance.presentation.name)[0] # change is here <<< mail.attach_file(instance.presentation, instance.presentation.read(), content_type) # <<< change is here also return mail.send()

参考： mimetypes.guess_type（）
