Using Heroku for Django Media Files

Question

On the heroku domain, I am not able to load my Media(Images Saved by using ImageField property) file images. However, I am able to see the images saved in the static field if I set debug = True

I save my images using the following command:

image = models.ImageField(upload_to=upload_location, null=True, blank=True, width_field="width_field", height_field = "height_field")

And I am able to reference them in my template by doing someething like this:

<img src="{{ instance.image.url }}" class="img-responsive">

Where instance is passed from my views.py like so:

instance = get_object_or_404(Post,slug=slug)
if instance.draft or instance.publish > timezone.now().date():
    if not request.user.is_staff or not request.user.is_superuser:
        raise Http404
share_string = quote_plus(instance.content)
context = {
    "title": "Detail",
    "instance": instance,
    "share_string":share_string,
}
return render(request,"post_detail.html",context)

Thanks

The Heroku filesystem is ephemeral, so dynos boot with a clean copy of the filesystem from the most recent deploy. Here are some ways to work around this:

1. AWS S3
2. If you don't want to set up an account with AWS to create an S3 bucket, Heroku has add-ons that handle storage and processing of static assets
