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.

{% extends "shop/base.html" %}
{% block content_area %}
{% for name in products %}
<div class="col-lg-3 col-md-3">
<div class="main_content_sidebar">
<div class="content_title">
<h2>{{name.product_name}}</h2>
</div>
<div class="image_space">
<img src="{{name.product_image.url}}" class="img-thumbnail" alt="">
</div>
<div class="content_p">
<p>Retail Price:{{name.product_retail_price}}</p>
<p>Quantity: {{name.product_quantity}}</p>
<p>Date: {{name.product_sell_date}}</p>
</div>
</div>
</div>
{% endfor %}
{% endblock %}


this is mysite(project)>>urls.py

from django.conf.urls import url, include
from django.contrib import admin
from django.conf.urls.static import static

from django.conf import settings
urlpatterns = [
url(r'^shop/',include('shop.urls')),
url(r'^admin/', admin.site.urls),
]
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)


This is my models.py file.

class ProductsName(models.Model):
product_name=models.CharField('name', max_length=50)
product_retail_price=models.IntegerField('retail price TAKA')
product_quantity = models.IntegerField('quantity')
product_sell_date=models.DateTimeField('buy date', auto_now_add=True)
product_image = models.ImageField(upload_to='upload/', blank=True, null=True)

def __str__(self):
return self.product_name

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/'
