Click here to start your Django download now

I am looking for a way to monitor the number of times a file has been downloaded. Here is my plan:

1) Instead of using

<a href="{{ file.url }}" download>...</a>

, I propose redirecting the user to a download view with a link like

<a href="download/{{ file.id }}/{{ file.name }}">...</a>

file.id and file.name are required for the proper functioning of the function below.

2) In the download view, I plan to record the download of the specific file using a function called registrate_dl. Additionally, I need to retrieve the value of {{ file.url }} as in the first link from the first paragraph.

3) After successfully registering the download for the specific file and obtaining {{ file.url }} as a variable named file_url.

However, if I simply use return redirect(file_url) at the end of the view function, it just redirects me to the file without initiating the download.

So, how can I return this file_url in a way that triggers the download?

If you want to include a file in your response, one way to do it is by returning the file directly. The process might vary depending on the type of file, but here's an example using CSV from a different source.

def csv_download(request):
    filename = "Your file name"
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="{}.csv"'.format(filename)
    writer = csv.writer(response)
    writer.writerow("Some content")
    messages.success(request, 'File downloaded successfully!')
    messages.warning(request, 'Please note: Some data may not be included due to filtering.')

    return response
