I am following a Django book which builds a web application. When I build a template, I get the same result as that of the book, except for my images - they are not there.
I am wondering what can be causing this issue. The images have correct URL's but when I try to open them, Django states "Page NOT found 404".
I am pasting the relevant code below. In addition, I include a screenshot of my directory tree.
shop/models.py:
class Product(models.Model):
category = models.ForeignKey(Category,
related_name='products')
name = models.CharField(max_length=200, db_index=True)
slug = models.SlugField(max_length=200, db_index=True)
image = models.ImageField(upload_to='products/%Y/%m/%d',
blank=True)
description = models.TextField(blank=True)
price = models.DecimalField(max_digits=10, decimal_places=2)
stock = models.PositiveIntegerField()
available = models.BooleanField(default=True)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
template:
<a href="{{ product.get_absolute_url }}">
<img src=" {% if product.image %}
{{ product.image.url }}
{%else %}
{% static 'img/no_image.png' %}
{% endif %}
">
</a>
views.py
def product_list(request, category_slug=None):
category = None
categories = Category.objects.all()
products = Product.objects.filter(available=True)
if category_slug:
category = get_object_or_404(Category, slug=category_slug)
products = products.filter(category=category)
return render(request, 'shop/product/list.html',
{'category': category,
'categories': categories,
'products': products})

I have a file name images inside the static. Your help is much appriciated
I'm building a photo blog via Django, it has a very basic structure:
1)a list page: each post has a cover picture
2)severals detail pages correspondant: each page contains multiple pictures.
At the list page, things are all good, the cover picture displayed correctely, but for the detail web page, the pictures that I uploaded from django admin won't show up, though they can be found in the local folder \media. I checked the page in Chrome, I got this: <img src(unknown) alt>. I'm confused.
Thanks a lot for your time and help.

Does not display an image!
image is exists, dut django didn't display any images on page, how to fix this?
this is my models.py
class All_Images_Of_The_Series(models.Model):
to_series = models.ForeignKey(Series, on_delete=models.CASCADE, blank=True, default=None)
image_of_all = models.ImageField(upload_to="previews/previews_for_series/", default=None,width_field="width_field", height_field="height_field")

height_field = models.IntegerField(default=0)
timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
updated = models.DateTimeField(auto_now_add=False, auto_now=True)
def __str__(self):
return "Active: |%s| and Poster: |%s| " % (self.is_active, self.is_poster)
class Meta:
ordering = ["-timestamp"]
verbose_name = 'All_Images_of_the_Series'
verbose_name_plural = 'All_Images_of_the_Series'
this is my views.py
def homeview(request, *args, **kwargs):
full_path = All_Images_Of_The_Series.objects.all()
context = {"full_path":full_path,}
return render(request, 'home.html', context)
this is my template
<div class="col-sm-3 right-side">
<div class="new-movies-block">
<a class="header" href="#/new/">
<div class="title">Новинки</div>
</a>
{% for one_to_one_path in full_path %}
<div class="movie-spacer" ></div>
<a class="new-movie" href="{{ one_to_one_path.to_series.get_absolute_url }}" title="{{ one_to_one_path.to_series.eng_name }}">
<div class="title-info">

<img src="{{ one_to_one_path.image_of_all.url }}" class="img-responsive">
</a>
{% endfor %}
</div>
</div>
If you look at the element code, the images, then in the line "src" there is a path to the picture, and it's working! But does not display the picture itself!
<img src="/media/previews/previews_for_series/1.png" class="img-responsive">
this is error in console(f12)
GET http://127.0.0.1:8000/media/previews/previews_for_series/1.png 404 (Not Found)
Do this !
from django.conf.urls import include, url
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'^series/', include("serials.urls", namespace='series')),
url(r'^', include("serials.urls", namespace='homeview')),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
just a quick thoughts, you don't show me the things you might need to work. For example if this if for development on the urls you need this https://docs.djangoproject.com/en/1.11/howto/static-files/#serving-files-uploaded-by-a-user-during-development and on your settings you may need something like that
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media")
I hope it helps
Best
Perhaps you haven't added the media to your urls.py
From django.conf import settings
# your stuff
if settings.DEBUG:
urlpatterns += patterns('',
(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
'document_root': settings.MEDIA_ROOT
})
)
I'm trying to write a simple blog using a Django framework. I want to have a cover image for a every post.
I uploaded an image via Admin site and everything seems to be fine but image is not rendering in a browser.
Here is my files:
