Django send email with attachement

Question

I tried to send some files in mail using Django EmailMessage class

The files attachment that I want to send are in DB, provided by each user during registration to my site.

I'have tried this but it does not work

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))

myapp/models:

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)

Traceback:

My question is : How to fix this

Answer 1

Since the file is stored in your DB, it will probably not be saved /media/documents/CNI/1847635-2524541_FZLHlIr.jpg at this location. So what you have to do is specify the filename, data, mimetype using the attach() method. Here is an example of how it should work:

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

You can read more at Django Docs. Look for attach(), and know that it is different from attach_file()

EDIT 1

Since you mentioned in the comments that id_card throws an error, I am assuming you are not fetching the correct model. From what I can see I am unsure if you are doing it correctly. You should fetch the Profile model instance in the following way:

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

and then in order to attach the file use:

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

Hope this helps!
