How to send email with attachment from form? - django

Question

I've been trying different ways to send an attachment from a submitted form but I'm not able to get it right.
my model:
from django.db import models
class Document(models.Model):
description = models.CharField(max_length=255, blank=True)
document = models.FileField()
uploaded_at = models.DateTimeField(auto_now_add=True)
views.py
from django.shortcuts import render, redirect
from django.core.mail import EmailMessage
from decouple import config
from .forms import ContactForm
def contact(request):
contact_form = ContactForm()
if request.method == "POST":
contact_form = ContactForm(request.POST, request.FILES)
if contact_form.is_valid():
name = request.POST.get("name")
email = request.POST.get("email")
subject = request.POST.get("subject")
message = request.POST.get("message")
upload = request.POST.get("upload")
email_content= EmailMessage("Message from django-structure project",
f"The user with name {name}, with the email {email},"
f" write the following: \n Subject: {subject} \n File{upload} \n\n Message: {message}",
"", [config('EMAIL_TO')], reply_to=[email])
try:
email_content.send()
return redirect("/contact/?valid")
except:
return redirect("/contact/?invalid")
return render(request, "contact.html", {"form": contact_form})
contact.html
<div class="row">
<div class="col">
<div class="form-group">
{% if "valid" in request.GET %}
<p style="color: blue;">Information sent successfully </p>
{% endif %}
<form action="" method="POST" enctype="multipart/form-data" style="text-align: center;">
{% csrf_token %}
<table style="color: dark; margin:20px auto;">{{form.as_table}}</table>
<input type="submit" value="Send" style="width: 150px;">
</form>
</div>
When I submit the form, I receive the message but in the content of the File, just the following string: "FleNone". (I have attached a pdf)
