How to download image or files from Django model

I'm kinda new to python and I'm creating a website that users can buy Hi-Res images and now I'm looking for a way to let user to download the images that they've bought, from the Django model, Here is my pic model:

class Pic(models.Model):
    name = models.CharField(max_length = 60, blank = False)
    description_sizes = models.TextField(blank = False, name = 'des_sizes', max_length = 360)
    captured_time = models.DateField(blank = False)
    price = models.IntegerField(blank = False)
    preview = models.ImageField(upload_to = f'static/post/preview/', null = False, blank = False)
    tags = models.CharField(max_length = 1000, blank = False)
    image_files = models.FileField(upload_to ='posts/ogFiles', null = True, blank = False)

My views.py :

def singlePostView(request, pic_id = None):
    pic = Pic.objects.get(id = pic_id)
    print(pic)

    context = {
    'pic':pic,
    }
    return render(request,"post/single_post_view.html", context)

I'm looking for way to make a button or link to download the image_file from pic model in the single view, and I've been searching for this for couple of days now and I've just came across these : xsendfile module

or using serve like this :

 <a  href="/project/download"> Download Document </a>

and in urls.py:

url(r'^download/(?P<path>.*)$', serve, {'document root': settings.MEDIA_ROOT}),

well for xsendfile module it's not really an efficient way bc

and for the serve because it's not a protected url user can download other files in other paths.

is there any alternative solution for downloading from Django model??

You need to tell the browser to treat the response as a file attachment.

According to Django document link This is how you can do -

response = HttpResponse(my_data, headers={'Content-Type': 'image/jpeg','Content- 
           Disposition': 'attachment; filename="foo.jpeg"'}).

Read about the Content-Disposition header.

You can add "download" attribute inside your tag to download files.

<a  href="/project/download" download> Download Document </a>
