的Django发送电子邮件与attachement

Question

我试图使用Django EmailMessage类

中的文件附件，我想送都在DB，注册到我的网站中每个用户提供发送邮件的一些文件。

I'have试过，但它不工作

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) 

回溯：

    File "C:\venvs\env1\lib\site-packages\django\core\handlers\exception.py", line 41, in inner 
response = get_response(request)

我的问题是：如何解决这个问题

由于文件存储在您的数据库，它可能不会在这个位置保存/media/documents/CNI/1847635-2524541_FZLHlIr.jpg。所以你需要做的是使用attach()方法指定文件名，数据和MIME类型。这里是它应该如何工作的一个例子：

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

你可以在Django Docs了解更多。寻找attach()，并知道它是不同于attach_file()

既然你在评论中提到id_card抛出一个错误，我假设你没有获取正确的模型。从我所看到的情况来看，我不确定你是否正确地做了这件事。你应该通过以下方式获取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 

，然后以附加的文件使用：

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

希望这有助于！
