Upload PDF File via Django Admin, Users Download from Link on Template

I’m trying to allow users to download a PDF file that I’ve previously uploaded to the MEDIA_ROOT folder via the admin console. I’ve emulated the answer in this post, however it’s incomplete and I can’t figure out how to fix this. Hoping someone can spot my issue in the code below.

settings.py

# Absolute filesystem path to the directory that will hold user-uploaded files.
# Example: "/home/media/media.lawrence.com/media/"
MEDIA_ROOT = str(BASE_DIR) + "/media/"

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash if there is a path component (optional in other cases).
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL = '/media/'

# Absolute path to the directory that holds static files.
# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = str(BASE_DIR) + "/static/"

# URL that handles the static files served from STATIC_ROOT.
# Example: "http://media.lawrence.com/static/"
STATIC_URL = '/static/'

models.py

from django.db import models

# Create your models here.
class ResumeModel(models.Model):
    pdf = models.FileField(upload_to="resume_app/media/resume/")
# So this file gets uploaded to root > media > resume_app > media > resume

admin.py

from django.contrib import admin
from .models import ResumeModel

# Register your models here.
admin.site.register(ResumeModel)

views.py

from django.shortcuts import render
from .models import ResumeModel

# Create your views here.
def resume(request):
    resume = ResumeModel.objects.all() # < Not sure if this part is needed?
    return render(request, 'resume.html', context={'resume':resume})

template.html

...
<a href="{{ resume.pdf.url }}">Click here to download PDF</a>
...

When I hover over this link, the url it’s pointing to is localhost:8083/resume/, which is the name of the page we’re currently on, so I think the <a href="{{ resume.pdf.url }}"> is not pointing to the correct url of the PDF file I’ve uploaded. The upload DOES work, the file IS in the root > media > resume_app > media > resume folder. What do I need to make the link work?

UPDATE

Thanks to the help of @tonio below, and apart from my oversight, I changed the line(s):

def resume(request):
    resume = ResumeModel.objects.all() # < Not sure if this part is needed?
    return render(request, 'resume.html', context={'resume':resume})

def resume(request):
    resume =  ResumeModel.objects.last()
    return render(request, 'resume.html', context={'resume':resume})

…which is fine for me as I will only have 1 resume in there, and the last entry will be the most recent upload. I then went into that app’s folder, and deleted the __pycache__ and migrations folders, performed python manage.py makemigrations resume_app and python manage.py migrate resume_app, restarted the server, opened app in incognito window and it worked as desired!

Answer

You’re sending all resume objects stored in the database to the template:

resume = ResumeModel.objects.all()

You can send an specific resume identified by their primary key (see this):

def resume(request, resume_id):
    resume =  get_object_or_404(ResumeModel, resume_id)
    return render(request, 'resume.html', context={'resume':resume})

Anyway, you can test the template sending the first resume in the database:

def resume(request):
    resume =  ResumeModel.objects.first()
    return render(request, 'resume.html', context={'resume':resume})
