A common UI pattern these days is to allow the user to either upload the file, import from a connected cloud storage account Google Drive, Dropbox and so on , or paste a link to the file located anywhere on the Internet.

The user might also be signing up via a social provider, with your application getting the URL to the user's profile image in the account data for the newly created user. Importing files from cloud storage will use their API directly and differs slightly from service to service. In this article, we'll only focus on the last case: when the user or a social auth provider supplies an URL to the file and we want to import it. What we want to do is download the file from the URL on a temporary location on the server, save it to the File field which will potentially have the effect of uploading it somewhere else, for example S3, if youse such a service for file storage , and remove any temporary files left.

Serves a file to the browser. This is used either for checking permissions before approving a downoad or as a fallback if the backend doesn't support publicly accessible URLs. So, you always have to provide a view that uses this function. Tries to generate a publicly accessible URL for the given file. Returns None if no URL could be generated.

The same function is available as a template filter. It takes the File object e.
