At least, not as I understand them. I'm looking at the next architectural level up. For example, creating an md5 or sha1 hash directory under a file root, where file uploads can be organized in /mm/dd folders. And providing the linkage from the user account in the SQL db, to their binary file directory. I was hoping someone else had packaged this kind of support for binary-objects-stored-in-files in a nice and purty application. :-) I'll chew on this more. Maybe a custom storage system backend is the way to go. (http://tinyurl.com/yjh7st4) John -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Flat file application for binary data?
Also check the FileField for info on how django handles files by default. Probably the best starting point. http://docs.djangoproject.com/en/dev/ref/models/fields/#filefield and sending files is a view like this: def project_download(request, project, filename, version): project_file = get_object_or_404(ProjectFile, project__slug__exact=project, name__exact=filename, version__icontains=version) file_name = os.path.basename(project_file.file.name) mimetype, encoding = mimetypes.guess_type(project_file.file.path) response = HttpResponse(mimetype=mimetype) response.write(project_file.file.path) response['Content-Disposition'] = 'attachment; filename=%s' %(file_name) The Content-Dispostion header is what lets the browser know there is a file coming (sorry for hitting send a bit early).

Flat file application for binary data?
I'm building a site that will include using lots of image files, audio clips, and video clips. Including users uploading these things and then later referencing them. I don't want to store this binary data in the database, but instead want to store them in disk files. I've looked for a Django app that manages flat files, and can't find one. By "manage," I mean functions like organizing the directory into a year/mo/date (for example) structure, returning filenames for new data to be recorded into a database table, and returning the binary data given a link. This stuff isn't rocket science, but I'd rather not code it from scratch. Anybody know of an suitable application for this?
