Python Question
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 %}

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/'
