Django random post not showing on base.html

Question

I'm trying to get ads to show on the sidebar of my website (in base.html). However the ad isn't displaying.

The code I'm using is:

views.py

from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import *
import random

def base(request):
    allSideAds=SideBarAd.objects.all()
    random_sideAd = random.choice(allSideAds) if allSideAds else None
    return render(request, 'base.html', {'random_sideAd': random_sideAd})

models.py

from django.contrib import admin
from django.db import models
from django.urls import reverse

class SideBarAd(models.Model):
    AdImage = models.ImageField(help_text='Enter Image Here')
    AdLink = models.URLField()
    MaxAdViews = models.PositiveBigIntegerField()
    AdViews = models.PositiveBigIntegerField()
    Approved = models.BooleanField()
    
    def get_absolute_url(self):
        return self.AdImage

base.html

        {% if random_sideAd %}
            <a href="{{ random_sideAd.AdLink }}">
                <img src="{{ random_sideAd.AdImage.url }}" alt="Ad Image">
            </a>
        {% endif %}

When I load a page, the ad that's in my database isn't shown through base.html.

Answer 1

I was able to figure out why this wasn't working. Instead of running this through views.py, I decided to use context_processors.py.

context_processors.py:

import random
from .models import SideBarAd


def sidebar_ad(request):
    sidebar_ads = SideBarAd.objects.filter(Approved=True)

    sidebar_ad_data = random.choice(sidebar_ads) if sidebar_ads else None

    return {'sidebar_ad': sidebar_ad_data}
