Django not displaying images after adding product details

Django can be able to display the image if I comment out the product details page.
I would like to know why it does that and how can I make it always display the images.
Product model
item_name = models.CharField(max_length=20)
item_description = models.TextField(
max_length=200, verbose_name="Item Description")
item_price = models.FloatField(default=0.00)
slug = models.SlugField(null=True, unique=True)
item_details = models.TextField(
max_length=1000, verbose_name="Item Details")
item_quantity = models.IntegerField(default=0)
item_availability = models.BooleanField(default=False)
is_item_featured = models.BooleanField(default=False)
is_item_recommended = models.BooleanField(default=False)
# Todo: add Is On Carousel Filter
item_brand = models.ForeignKey(Brand, null=True, on_delete=models.CASCADE)
item_categories = models.ForeignKey(
Category, null=True, on_delete=models.CASCADE)
item_image = models.ImageField(upload_to='images/product/',
default="images/product/image-placeholder-500x500.jpg")
Product Views
class HomePageView(ListView):
model = Product
template_name = 'product/index.html'
class ProductListView(ListView):
model = Product
template_name = 'product/product_list.html'
def product_detail(request, slug):
objec = get_object_or_404(Product, slug=slug)
template_name = 'product/product_detail.html'
return render(request, template_name, context={'object': objec})
Product Templates
{% for product in object_list %}
<div class="col-md-3 col-sm-6">
<div class="product-grid4">
<div class="product-image4">
<a href="product/{{ product.slug }}">
<!-- <img src="{{ product.item_brand.brand_image.url }}" alt="{{ product.item_brand.brand_name }}" width="30px"> -->
<img class="pic-1" src="{{ product.item_image.url }}" alt="{{ product.item_name }}">
</a>
<!-- <span class="product-new-label">Recommended</span> -->
<!-- <span class="product-discount-label">-10%</span> -->
</div>
<div class="product-content">
<h3 class="title">{{ product.item_name }}</h3>
<div class="price">
Kshs. {{product.item_price }}
<!-- <span>$16.00</span> -->
</div>
<a class="add-to-cart" href="{% url 'add-to-cart' product.slug %}">ADD TO CART</a>
</div>
</div>
</div>
{% endfor %}
Product Urls
url(r'product/(?P<slug>.+)$', views.product_detail, name='product-detail'),
url('^$', views.HomePageView.as_view(), name='landing_page'),
url('shop/', views.ProductListView.as_view(), name="product-list")
Settings.py
.....
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/
STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles")

os.path.join(BASE_DIR, "static"),

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
The error I get. Please note the error only comes up when product_detail view and it's url are called. When they are commented out, the images are displayed.
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/media/images/product/airmax_98_bVXgZPB.jpg
Raised by: shop.views.product_detail
No Product matches the given query.

If you don't want have problems when you change urlpattern, you should replace <a href="product/{{ product.slug }}"> to <a href="{{ product.get_absolute_url }}"> and add a bit of code to models.py
*product fields goes here*
def get_absolute_url(self):
return reverse('product-detail', args=[self.slug])
And don't forget from django.urls import reverse
I've noticed that your django is not pretty new, and if Can not import reverse from django.urls

The problem is with how the url is being displayed.
I should Use path instead of url like so:
Product Urls
......
path('product/<slug>/', views.product_detail, name='product-detail'),
path('shop/', views.ProductListView.as_view(), name="product-list"),
......
I still don't have a clear understanding as to why I should use path instead of url

Django not serving images based on ImageFiled

I'm having issues serving images based on the ImageField in Django.
models.py part looks like that:
class Post(models.Model):
author = models.ForeignKey(Author, on_delete=models.CASCADE)
category = models.ManyToManyField(Category)
trip = models.ForeignKey(Trip, on_delete=models.CASCADE)
main_image = models.ForeignKey(Image, on_delete=models.CASCADE, related_name='main_image')
images = models.ManyToManyField(Image, related_name='images')
class Image(models.Model):
name = models.CharField(max_length=32)
picture = models.ImageField(upload_to='pictures/', blank=True)
trip = models.ForeignKey(Trip, on_delete=models.CASCADE)
taken = models.DateTimeField(blank=True, null=True)
uploaded = models.DateTimeField(default=timezone.now)
def __unicode__(self):
return self.name
settings.py contains the MEDIA_URL and MEDIA_ROOT:
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.1/howto/static-files/
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
Also included what I've found in other SO topics in the urls.py:
from django.contrib import admin
from django.urls import path, include
from django.conf.urls import url
from django.contrib.staticfiles.urls import static, staticfiles_urlpatterns
from django.conf import settings
from markdownx import urls as markdownx
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('blog.urls')),
url(r'^markdownx/', include('markdownx.urls')),
] + staticfiles_urlpatterns() + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
In the end I put it in the html template like that:
{% extends 'blog/base.html' %}
{% block leftcolumn %}
{% for post in posts %}
<div class="leftcolumn">
<div class="card" style="max-width: 100%">
<h2>{{ post.title }}</h2>
<h5>published: {{ post.published_date }}, by: {{ post.author }}</h5>
<div><img src="{{ post.main_image.url }}"></div>
<p>{{ post.byline }}</p>
</div>
</div>
{% endfor %}
{% endblock %}
But the image is not shown..
I can see the image if I go to the url host:8000/media/pictures/test_photo.jpgand in general I can display images on the page (e.g. within django-markdownx field) but not through ImageField url.
Any ideas what's wrong here?

This line:
<div><img src="{{ post.main_image.url }}"></div>
should be:
<div><img src="{{ post.main_image.picture.url }}"></div>
The reason is your model Image does not have an url method. The method belongs to the ImageField, in this case picture.

How to display image from model in Django

To be clear, I have tried researching this on my own but since I'm still very new to Django I am unable to understand the solutions here. I also have read the documentation and I don't understand what I'm doing wrong. I cannot get the images located in the "ad_pictures" directory to display in the HTML.
Here's my code:
settings.py
STATIC_URL = '/static/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
urls.py (project)
from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^accounts/', include('accounts.urls')),
url(r'^classifieds/', include('classifieds.urls')),
] +static(settings.MEDIA_URL, document_ROOT=settings.MEDIA_ROOT)
urls.py (classifieds app)
from django.conf.urls import url
from . import views
app_name = 'classifieds'
urlpatterns = [
url(r'^create/', views.create, name='create'),
url(r'^latestads/', views.latestads, name='latestads'),
]
models.py
class Post(models.Model):
title = models.CharField(max_length=150)
price = models.CharField(max_length=100)
body = models.TextField()
pub_date = models.DateTimeField(null=True)
author = models.ForeignKey(User, null=True)
category = models.CharField(max_length=150, null=True)
picture = models.ImageField(upload_to='ad_pictures', default='')
latestads.html
{% for post in posts.all %}
<div class="advertisements">
<div class="a-title">
<h3>{{ post.title }}</h3>
</div>
<div class="a-image">
<img src="{{ post.picture.url }}">
</div>
<div class="a-content">
<p>{{ post.body }}</p>
</div>
<div class="a-date">
<p>{{ post.pub_date }} by {{ post.author }}</p>
</div>
</div>
<img src="{{ post.image.url }}">
{% endfor %}
Picture of directory structure:
here
Html output:
here
I'm sure part of the problem is the "post.picture.url" in the HTML.
Any insight is greatly appreciated.
Thanks

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^accounts/', include('accounts.urls')),
url(r'^classifieds/', include('classifieds.urls')),
] +static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
please change document_ROOT to document_root

Unable to display ImageField within Django template

I hope you can help me withmy Django project. I am able to upload an images under a media_cdn folder, inside a folder based on the name of the slug. The problem occurs when I try to display the image inside my post list and post.
Can you please have a look at my code and offer a solution. I spent hours trying to get it to work. Please help.

if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
I don't know what else to try to call that image from the folder. Any advice would be greatly appreciated. Thank you!

Use post.image.url instead of post.instance.image.url. Check the documentation.
ImageField inherits all the attributes of the FileField which includes url.
