If you need to craft a special request for example set headers, cookies, query params and so on , you may want to implement the same thing using the awesome requests library. Here, we're creating a temporary file using TemporaryFile from the standard library. We're using it as a context processor, so it'll automatically clean up delete temporary file after the block of the code is exited.

We then make a GET request with requests in streaming mode, so it doesn't try to download the entire file in memory. Instead it gives us chunks, which we save to a temporary file. This approach avoids causing problems if the files to download are big relative to available memory you never know when your user might attempt to set a two-hour full-HD movie as their avatar picture. The urlretrieve function also works in the same way.

After we've downloaded the content, we seek to the beginning of opened file so we can read from the start , and tell the FileField to save it. We use the same logic for naming the file as before. In this case, we haven't used any extra features the requests library gives us to avoid complicating the example. In the real world you can do anything the requests library supports here and if you don't need it, consider using the simpler urlretrieve approach.
