In this tutorial we will briefly look at file uploads, and how to set this up in your coding. When Django handles a file upload, the file data ends up placed in request.FILES (for more on the request object see the documentation for request and response objects).This document explains how files are stored on disk and in memory, and how to customize the default behavior. The upload form is the same as the one in the previous section. For example, HTML file uploads could be used to allow users to upload avatars, or allow an internal team to upload photos of products to a website or app. Processing the actual contents of a multipart file upload.Configuring your DiskFileItemFactory and ServletFileUpload object.The following example contains such an HTML form and a server-side script written in PHP.
