Question

我尝试使用Django EmailMessage类

在邮件中发送一些文件

我要发送的文件附件在DB中，由每个用户在注册到我的网站时提供。

我已经尝试了这个，但它不起作用

的myapp / views.py：

from django.core.mail import EmailMessage

def contactUber(request,id):
    user = User.objects.get(id=id)
    msg = EmailMessage(
        'Hello', #subject
        'Body goes here', #content
        'vitalysweb@gmail.com', #from
        ['uber@uber.com'] #to
        )
    msg.attach_file(user.profile.id_card.url) #the file that i want to attach
    msg.send()
    messages.success(request, "Email envoyé avec succes") #success msg
    return redirect(user_detail, id=str(id))

的myapp /型号：

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    birth_date = models.DateField(('Date de naissance'), null=True, blank=True)
    #DOCUMENTS TO UPLOAD
    id_card = models.FileField(('Carte Nationale d\'Identité'), upload_to='documents/CNI')
    drive_licence = models.FileField(('Permis de conduire'), upload_to='documents/RIB')
    uploaded_at = models.DateTimeField(('Ajouté le'), auto_now=True)
    docs_are_checked = models.BooleanField(('Documents validés'), default=False)

我的问题是：如何解决这个问题

Answer 1

由于文件存储在您的数据库中，因此可能无法在此位置保存/media/documents/CNI/1847635-2524541_FZLHlIr.jpg。所以你要做的是使用attach()方法指定文件名，数据，mimetype。以下是它应该如何工作的示例：

msg.attach(user.profile.id_card.name, user.profile.id_card.read(), user.profile.id_card.content_type)

您可以在Django Docs阅读更多内容。查找attach()，并知道它与attach_file()

不同

由于您在评论中提到id_card会引发错误，我假设您没有提取正确的模型。从我所看到的，我不确定你是否正确地做到了。您应该按以下方式获取Profile模型实例：

someVar = Profile.objects.get(user=request.user) # assuming the current user is the one that you would like to be

然后为了附加文件使用：

msg.attach(someVar.id_card.name, someVar.id_card.read(), 'image/png') # assuming you will be attaching png's only

希望这有帮助！
