Django Python: Get the uploaded file name and add it to the body of the email message

Question

I'm using Django for a simple contact form with a file upload.

I'm not attaching the file to the email; I'm simply uploading it to the server via forms.py. But I need to add the file name in the body of the contact form email so I know which file has been uploaded by which email user.

How do I get the uploaded file name and add it to the body of the email?

Does file = fs.save(request_file.name, request_file) output the file name?

If not, how do I get the uploaded file name? And add it to the email?

I am also aware that Django adds a random string of characters to the uploaded file name if it sees an existing file with the same name n the upload directory, so in that case, I need that file name included.

views.py

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

from django.shortcuts import render, get_object_or_404, redirect

from django.core.files.storage import FileSystemStorage

from contactform.forms import ContactForm
from contact.settings import EMAIL_HOST_USER, EMAIL_PORT, EMAIL_HOST_PASSWORD, EMAIL_HOST

def thanks(request):
    return render(request, 'thanks.html', {})

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST,request.FILES)

        request_file = request.FILES['document'] if 'document' in request.FILES else None
        if request_file:
             fs = FileSystemStorage()
             file = fs.save(request_file.name, request_file)
             fileurl = fs.url(file)

        if form.is_valid():
            form_data = form.cleaned_data
            msg = MIMEMultipart()
            msg['From'] = EMAIL_HOST_USER
            msg['To'] = EMAIL_HOST_USER
            msg['Subject'] = f'Site Email'
            message = f'Name: {form_data["name"]}\n' \
                      f'Email address: {form_data["email_address"]}\n\n' \
                      f'{form_data["message"]}' // How do I insert the file name in the message body?
            msg.attach(MIMEText(message))

            with smtplib.SMTP(EMAIL_HOST, EMAIL_PORT) as server:
                server.ehlo()
                server.starttls()
                server.login(EMAIL_HOST_USER, EMAIL_HOST_PASSWORD)
                server.sendmail(EMAIL_HOST_USER, EMAIL_HOST_USER, msg.as_string())

            return redirect('contactform:thanks')
    else:
        form = ContactForm()

    return render(request, 'contact.html', { "form": form })

No need to use another msg field; this works. All that is needed is file, since file = fs.save(request_file.name, request_file) gets the filename.

This also adds the correct file name in the message if Django has added random characters to prevent same name file overwrites:

message = f'Name: {form_data["name"]}\n' \
                      f'Email address: {form_data["email_address"]}\n\n' \
                      f'File Uploaded: {file}\n\n' \
                      f'{form_data["message"]}'

You can use request.FILES.get('file_name').name like this:

msg['Message'] = f'Hi, You uploaded {request.FILES.get('filename').name}. Thanks!'

Don't forget to add .get before file name
