How to get the name and url of an uploaded file?

I am using the following files:

settings.py:

MEDIA_URL = '/data/'

MEDIA_ROOT = os.path.join(BASE_DIR, 'data')

urls.py:

urlpatterns = [

path("photo/upload", views.upload_pic, name="uploadpic ")

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

models.py:

class Pic(models.Model):

name = models.CharField(max_length=255)

photo = models.FileField(upload_to="data/media/%Y/%m/%d")

def __str__(self):

return self.url

def path(self):

return self.url

forms.py:

from django import forms

class DocumentForm(forms.Form):

docfile = forms.FileField(

label='Select a file',

help_text='any valid file'

)

views.py:

def upload_pic(request):

documents = Pic.objects.all()

import uuid

name = uuid.uuid4().hex[:6].upper()

if request.method == 'POST':

form = DocumentForm(request.POST, request.FILES)

if form.is_valid():

print(request.FILES)

newdoc = Pic(name=name, photo=request.FILES['docfile'])

newdoc.save()

return render(request, 'clinic/list.html', {'documents': documents, 'form': form, 'msg': 'success'})

else:

form = DocumentForm() # A empty, unbound form

return render(request, 'clinic/list.html', {'documents': documents, 'form': form})

template: clinic/list.html

{% extends 'clinic/newbase.html' %}

{% load static %}

{% block content %}

{% csrf_token %}

<button type="submit">Upload</button>

</form>

{% if uploaded_file_url %}

<p>File uploaded at: <a href="{{ uploaded_file_url }}">{{ uploaded_file_url }}</a></p>

{% endif %}

<p><a href="{% url 'index' %}">Return to home</a></p>

{% endblock %}

However in the rendered html, the urls are blank:

<ul>

</ul>

<p></p>

<p><label for="id_docfile">Select a file:</label> max. 42 megabytes</p>

<p>

</p>

</form>

How can I get the media name and url in the rendered template?

Sincerely yours,

Joel G Mathew
