I have a record label website im building and I want to populate a navbar dropdown list with artists from the Artst object Artist.objects.all().
I have it working in one app "music" but only when I append "/artistlist/" onto the end. Any other URL doesnt populate the list.
I want the list to always be there as its a navbar item. At the moment I am trying to get a context_processors.py working.
youtube tutorial im following for the exactsame issue
I could use some help as I'm clearly doing something stupid, or overlooked something basic. On all other urls it triggers the else I added "We currently dont have any artists yet..".
Hope it makes sense to someone. Any help is greatly appreciated.
base.html
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<div class="dropdown-item" href="#">
{% if all_artists %}
<ul>
{% for artist in all_artists %}
<li class="dropdown-item">
<a href="{% url 'music:artist' artist.id %}">
<img src="{{ artist.artist_logo.url }}" style="width: 100px"><br>
{{ artist.artist_name }}<br>
{{ artist.artist_url }}<br>
</a>
</li>
{% endfor %}
</ul>
{% else %}
<h3>We currently dont have any artists yet..</h3>
{% endif %}

I found this vieo which is exactly the same issue, and tried adjusting the context processor to te above, and also tried just:
from music.models import Artist:
settings.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')]
,
'APP_DIRS': True,
'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',
'music.context_processors.all_artists',
],
},
},
]
the only thing you want to do is change the return key value to all_artists because you fetch all data through all_artists key in your base.html but according to your code there is not any all_artists found do change in the last line in context_processor.py and you are good to go
music/context_processors.py
from .models import Artist
def all_artists(request):
artist = Artist.objects.all()
return {'all_artists':artist}

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")
is_poster = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
width_field = models.IntegerField(default=0)
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">
{{ one_to_one_path.to_series.season_of_this_series.number_of_season }} сезон {{ one_to_one_path.to_series.number_of_series }} серия
</div>
<div class="date">{{ one_to_one_path.to_series.timestamp_rus }}</div>
<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)

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 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 images I uploaded through django admin, but they are not displaying. The weird thing is that I have another project with the EXACT same code and it works. object.image.url outputs /media/media/image.jpg as does my other project. But this project does not show the image. if I put an image from my static folder or if I hardcode an image, it works fine. The problem is only when I try an image uploaded from the admin it does not work. Am I missing something in my settings.py file? or anywhere?

I believe you need to add the media urls to your urls.py. Something like:
from django.conf import settings
from django.conf.urls import url
from django.conf.urls.static import static
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('home.urls'), name="home"),
] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)
On production environment Django does not load the media root automatically so that we can we can overcome that issue by adding following after url patterns:
urlpatterns = [
''''
your urls
''''
] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)
If you are using more than one app and including app urls on main app url, just add this on main project url.
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.

image = models.ImageField(upload_to="images/%Y/%m/", blank=True, null=True)
content = models.TextField()

I'm currently learning how to upload and display images in Django but I've run into a block where I can't figure out how to call the images location from the database and then display it in a template... What am I missing?
settings
MEDIA_ROOT = '/Users/chr/Desktop/DJANGO-APP/media/'
MEDIA_URL = '/media/'
models
class Product(models.Model):
product_name = models.CharField(max_length=200)
product_description = models.TextField()
def __unicode__(self):
return self.product_name
class Image(models.Model):
product_image = models.ForeignKey(Product)
image = models.ImageField(upload_to='image')
views
def productpage(request, product_image_id):
product = get_object_or_404(Product, pk=product_image_id)
render(request, 'polls/productpage.html', {'product': product})
html
<h1>{{ product.product_name }}</h1>
<br>
{{ product.product_description }}
<br>
{{ product.image.url }}
EDIT:
urls.py (main)
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^polls/', include('polls.urls', namespace="polls")),
url(r'^admin/', include(admin.site.urls)),
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
def productpage(request, product_image_id):
product = get_object_or_404(Image, product_image=product_image_id)
render(request, 'polls/productpage.html', {'product': product})
I guess product_image_id refers to the product ID?
