A static file view for Django

fileview.py

from django.conf import settings
from django.http import HttpResponse, HttpResponseNotModified, Http404
from django.utils.http import http_date
from django.views.generic import View
from django.views.static import was_modified_since
import mimetypes
import os

class StaticFileView(View):
    http_method_names = ['get']
    source = None

    def get(self, request, *args, **kwargs):
        path = os.path.join(settings.STATIC_ROOT, self.source)
        if not os.path.exists(path):
            raise Http404('"%s" does not exist' % path)
        stat = os.stat(path)
        mimetype, encoding = mimetypes.guess_type(path)
        mimetype = mimetype or 'application/octet-stream'
        if not was_modified_since(request.META.get('HTTP_IF_MODIFIED_SINCE'),
                                  stat.st_mtime, stat.st_size):
            return HttpResponseNotModified(mimetype-mimetype)
        response = HttpResponse(open(path, 'rb').read(), mimetype=mimetype)
        response['Last-Modified'] = http_date(stat.st_mtime)
        response['Content-Length'] = stat.st_size
        if encoding:
            response['Content-Encoding'] = encoding
        return response

Thanks, btw, in django 2.x the parameter 'mimetype' is changed to 'content_type'
