Error sending a file using Django - file turns out empty

This is my views.py files:

from django.http import HttpResponse

def render(request):
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="somefilename.pdf"'
    response['X-Sendfile'] = '/files/filename.pdf'
    # path relative to views.py
    return response

When I run the server and request 

http://localhost:8080/somestring

I get an empty file called somefilename.pdf. I suspect that there is some crucial part missing in render.

The other parts of this app outside of views.py are correct to my understanding.

Here is the code that solved my problem:

from django.http import HttpResponse
from wsgiref.util import FileWrapper

def render(request): 
    response = HttpResponse(FileWrapper(open('file.pdf', 'rb')), content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="somefilename.pdf"'

    return response

The manage.py runserver development serer doesn't support X-Sendfile. In production, you need to enable X-Sendfile for your server (e.g. Apache).

You may find the django-sendfile package useful. It has a backend that you can use in development. However, it hasn't had a release in some time, and I found that I had to apply pull request 62 to get Python 3 support.
