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.

am trying to show pic in django tempate but its not working
here is my settings.py where the path of static and media file
STATIC_URL = '/static/'
STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'),
]
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR , "media")
this is my model.py
the image is store under static/img folder
class Loader_post(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="Loader")

this is my html template for showing user posted data

<a class="btn btn-primary" href="{% url 'Loader:Update' loader.id %} ">update</a>
</div> {% endfor %} {% endblock content %}
this is my urls.py
from django.urls import path

path('update/<int:pk>', views.Loader_post_update.as_view(template_name="post_detail.html"), name="Update")
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
how can i remove this error or any bug in my code?
Take a closer look
First of all, you use different names. In the models.py the image attribute corresponds to image_of_load, whereas in your template the src is equal to {{loader.image.url}} not {{loader.image_of_load.url}}. Second, try to put {% load static %} at the very top of your file, which is an advice from the documentation, at least above the {% block content %} tag.
I think that on the models.py file, you should use upload_to='img' because you have set your static folder directory. Remember that the uploaded images by users go to your media folder / URL, not your static folder. The static folder is for CSS files and images that you serve, such as your website's logo.
I hope that helps. Feel free to ask me any more questions!
I only see the file path in the template. I can't see the file itself.
(django 3.x)
settings.py
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]

<h4 class="card-title">{{girdi.bKaydi}}</h4>
<h4 class="card-title">{{girdi.cKaydi}}</h4>
<h4 class="card-title">{{girdi.yuklemeTarihi}}</h4>
you have to loop through your queryset and .url to the image
{% for girdi in girdiler %}
<img class="card-img-top" src="{{ girdi.upload.url }}">
<h4 class="card-title">{{girdi.aKaydi}}</h4>
<h4 class="card-title">{{girdi.bKaydi}}</h4>
<h4 class="card-title">{{girdi.cKaydi}}</h4>
<h4 class="card-title">{{girdi.yuklemeTarihi}}</h4>
{% endfor %}
<img class="card-img-top" src="girdi.upload.url"> #add url after fieldname like this
try this
{% for girdi in girdiler %}
<img class="card-img-top" src="{{me.upload.url}}">
{% endfor %}
and to your model
class EkleModel (models.Model):
upload = models.FileField(upload_to='image/', null=True, blank=True,FileField)

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:

Html output:
here
I'm sure part of the problem is the "post.picture.url" in the HTML.
Any insight is greatly appreciated.
Thanks

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.

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.
