Django link download file

You can change file name and path as per your requirement. If you want to download the file via template, just add the hyperlink to the file as shown below in any template. In this case, you need to modify the views. In the above code, if the filename is empty, then Django will load file. You can use the same method for downloading PDF files or other types of files too.

Just update the hyperlink in file. Alternatively, you can also fetch the file path from database, if you want. In this article, we have learnt how to download file in Django. You can modify these steps as per your requirement. The urlretrieve function in the standard library is great if you only need to download a static file and if you don't need to do anything funny with the request.

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.
