Django is not serving media files uploaded by user on heroku - django

Question

I have tried everything but somehow i cannot see images uploaded by user.I have deployed code on heroku and every static file is getting loaded properly. User is even going to correct path of image but somehow server is showing errors of not finding image.
Settings.py
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.8/howto/static-files/
STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'
# Extra places for collectstatic to find static files.
#STATICFILES_DIRS = (
# os.path.join(PROJECT_ROOT, 'static'),
#)
STATICFILES_DIRS = (
os.path.join(PROJECT_ROOT, 'static'),
)
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
Models.py
#this is for photos upload by user
class You(models.Model):
user = models.ForeignKey(User,null=True)
name=models.CharField(max_length=30,blank=True,default='pictures/videos')
docfile = models.FileField(upload_to='documents/%Y/%m/%d', null=True,blank=True)
def __unicode__(self):
return self.user.username
#Views.py(To upload files)
#login_required
def upload(request):
if request.method == 'POST':
newdoc = You(docfile = request.FILES['file'],user=request.user)
newdoc.save()
msg='dee'
# Redirect to the document list after POST
return HttpResponse(json.dumps({'message': msg}))
else:
form = DocumentForm()
# Render list page with the documents and the form
return render(request,'mat_upload.html',{'form':form})
Template(gallery.html)
{% for document in documents %}
<img class="img-responsive" src="{{MEDIA_URL}}/media/{{ document.docfile }}" alt="hiiii" style="max-width: 100%;
height: 250px;" />
{% endfor %}
#login_required
def gallery(request):
documents = You.objects.filter(user=request.user)
return render(request,'gallery.html',{'documents': documents,})

You cannot save user-uploaded files locally on Heroku. The filesystem is ephemeral, and does not persist across dyno restarts or between concurrent dynos. You need to upload them somewhere more permanent; a popular choice is Amazon S3, and there are plenty of libraries that will do that for you.
