Django 1.10 or later: base.html override not working

I am creating a site in Django with a custom view, and want to link to that view on the admin page. But even though I've followed the directions to override in Documentation or Youtube, but i won't show the changes in the overide file.
{% extends "admin/base.html" %}
{% block title %}{{ title }} | {{ site_title|default:_('Django site admin') }}{% endblock %}
{% block branding %}
<h1 id="site-name">Test</h1>
{% endblock %}
{% block nav-global %}{% endblock %}
My base.html in ratonix\templates\admin

I've restarted the server, as well as used different browsers, and none of my changes show up.
Am I doing something wrong anywhere, or are the instructions given by the tutorial just plain incorrect?

The order of INSTALLED_APPS affects the override order.
If you have templates/admin/base.html in the ratonix app, then ratonix must come before django.contrib.admin in INSTALLED_APPS for that template to be used.
Since you also have DIRS in your TEMPLATES configuration, you could also use <PROJECT>/templates/admin/base.html, and that would be used; per the documentation,
If you have app and project templates directories that both contain overrides, the default Django template loader will try to load the template from the project-level directory first. In other words, DIRS is searched before APP_DIRS.
Note the preferred customization point for the admin is admin/base_site.html.

Python-Django-Heroku not able to locate images in heroku, images not visible

so I recently deployed my django/python website (that used sqllite as a database) to heroku which hosts websites for free, everything is functioning normally like when I used to run localhost in my browser, except that this project is using postgressql database with heroku and images aren't appearing on my website, I looked everywhere and I think it has to do with the uploads file in the database(the path of the image is still the same but the location of the image changed).
local host image link: "http://localhost:8000/image/download/uploads/products/white_shirt_MERETfT.jpg"
heroku image link: "https://supremelebanon.herokuapp.com/image/download/uploads/products/offwhite_shirt_tQWa19c.jpg"
it says image not found for when I load the website on heroku hosting.
Please anyone I'm still a newbie with heroku I dont really know how it works, if anyone can help it would be much appreciated, thanks in advance.

A brief explanation
We have to add the whitenoise that allows you to serve files in production, and also if you notice, heroku uses postgres as a DB in production, so it is better to use that for production.

After logging in (in my Django app) I get the 403 error

When I run my Django application (via python manage.py runserver) I get the login screen, however when I try to login it redirect me to the page that says:
Forbidden (403)
CSRF verification failed. Request aborted.

There are questions similar to mine here on stackoverflow but unfortunately the answers are not helpful to me...
Additional notes on what I tried:
I am allowing cookies in my browser.
My view functions pass a request to the template's render method.
In the template I am adding {% csrf_token %} inside each POST form.
I also tried setting the CSRF_COOKIE_DOMAIN = None and CSRF_COOKIE_SECURE = False but it made no difference.
It would be great if anyone could help me with this, I am really stuck...
EDIT:
If you give me thumbs down, can you please just let me know what I did wrong? I am new here, still adapting... and if this is too easy for you and that is the reason for the thumbs down, please leave an answer I will appreciate it. Thank you!
2nd EDIT: Adding the relevant parts of the template and views.py file, where the csrf token is used. It is also worth mentioning that when the user logs in he/she is supposed to go to the homepage (that contains no POST forms and consequently no csrf tokens), and chose where to go next.
views.py (relevant part)
#login_required(login_url='/login/')
def dining(request):
#request is POST when user filters the city
if request.method == 'POST':
filter_city = FilterCityForm(request.POST)
if filter_city.is_valid():
filter_city = filter_city.save(commit=False)
city = str(filter_city.name)
#...
# here I'm doing some calculations and querying depending on the chosen city
#...
filter_city = FilterCityForm(initial={'name':city})
else:
filter_city = FilterCityForm(initial={'name':'Toronto'})
return render(request, 'dining.html', {'filter_city':filter_city})
dining.html (relevant part):
<div name='dropdown'>
<form action="" method="POST">
{% csrf_token %}
City: {% for widget in filter_city %}
{% if widget.errors %}
{% for error in widget.errors %}
<span style="color: red">{{ error }}</span><br>

Not properly render image from Django model

I am making a simple app(Django version 1.11+python3.5+). I want to show images on my homepage(web app) from Django models. I can upload successfully from Django admin panel. But image cant renders properly. The image does not show in the homepage. This is my HTML file.

When I visit my homepage, I can't see any image. But I see image link If I open my browser dev tools.
chrome dev tool
if I click that image link from chrome dev tool. I got andjango doesn/t found that image url error.
Also my folder structure is:
mysite
shop
manage.py
path_to
db.sqlite3

The issue is that the your MEDIA_ROOT is not being served and Django cannot append the correct url. In your project urls.py add the following at the end:
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
And in the setttings.py add the correct paths for:
MEDIA_ROOT = os.path.join(BASE_DIR,'path_to_/media_folder')
MEDIA_URL = '/media/'

Issue get resolved
,What I did I added static library in options
following is code
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
'libraries': { # Adding this section should work around the issue.
'staticfiles' : 'django.templatetags.static',
},
},
This worked for me
