AttributeError When Retrieving Object in Django

Question

For every movie download on my webapp, I want to inform the uploader through mail that his movie have been downloaded. I wrote the below code, it seems I'm finding it hard to get the query right.

  AttributeError at /download/

 'unicode' object has no attribute 'email'

Models:

class Emovie(models.Model):
    User=models.ForeignKey(User)
    movie_file=models.FileField(upload_to='miiv')
    movie_name=models.CharField(max_length=50)
    email=models.EmailField()   #email of the uploader
    #other fields follows

Views.py

@login_required
def document_view(request, emovie_id, urlhash):
    document=Emovie.objects.get(id=emovie_id, urlhash=urlhash)
    downstats=Emovie.objects.filter(id=emovie_id, urlhash=urlhash).update(download_count=F('download_count')+1)
    #where email notification starts
    notify=Emovie.objects.filter(id=emovie_id.email)
    send_mail('Your file has just been downloaded','this works','[email protected]',[notify])
    response = HttpResponse()
    response["Content-Disposition"]= "attachment; filename={0}".format(document.pretty_name)
    response['X-Accel-Redirect'] = "/protected_files/{0}".format(document.up_stuff)
    return response

How can I go about this?

The error happens here: Emovie.objects.filter(id=emovie_id.email).

emovie_id is a unicode (string) object which means you can't do .email on it. Given that you want to filter on id= I think you meant to write: Emovie.objects.get(id=int(emovie_id)).

..and [notify.email] instead [notify] in the next line.

I'm getting this error. 'QuerySet' object has no attribute 'email'. Any idea?

I've fixed it. It Should be get() not filter(), Like Emovie.objects.get(id=int(emovie_id))

I have a question, after making the changes, django do send more than one mail to the uploader, when a user download the movie once. why is this happening?

replace

notify=Emovie.objects.get(id=emovie_id).email

with

notify=Emovie.objects.filter(id=emovie_id.email)

It will work fine...

emovie_id will be unique for each emovie.. So Above query will work in all condition.

I did what you said before asking for help on SO. It's not working.
