So far I made it to the part where a user uploads an image but how can I use those images which are located in my media folder? Here is what I tried :
my view:
#I even tried to import MEDIA_ROOT to use it in my template...
#from settings import MEDIA_ROOT
def home(request):
latest_images = Image.objects.all().order_by('-pub_date')
return render_to_response('home.html',
#{'latest_images':latest_images, 'media_root':MEDIA_ROOT},
{'latest_images':latest_images,},
context_instance=RequestContext(request)
)
my model:
class Image(models.Model):
image = models.ImageField(upload_to='imgupload')
title = models.CharField(max_length=250)
owner = models.ForeignKey(User)
pub_date = models.DateTimeField(auto_now=True)
my template:
{% for image in latest_images %}
<img src="{{ MEDIA_ROOT }}{{ image.image }}" width="100px" height="100px" />
{% endfor %}
and my settings.py MEDIA_ROOT and URL:
MEDIA_ROOT = '/home/tony/Documents/photocomp/photocomp/apps/uploading/media/'
MEDIA_URL = '/media/'
So again here is what I am trying to do: Use those images in my templates!
If you use the url
attribute, MEDIA_URL
is automatically appended. Use name
if you want the path without MEDIA_URL
. So all you need to do is:
<img src="{{ some_object.image_field.url }}">
On development machine, you need to tell the devserver to serve uploaded files
# in urls.py
from django.conf import settings
if settings.DEBUG:
urlpatterns += patterns('',
url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
'document_root': settings.MEDIA_ROOT,
}),
)
{# in template, use sorl-thumbnail if your want to resize images #}
{% with image.image as img %}
<img src="{{ img.url }}" width="{{ img.width }}" height="{{ img.height }}" />
{% endwith %}
# furthermore, the view code could be simplified as
from django.shortcuts import render
def home(request):
latest_images = Image.objects.order_by('-pub_date')
return render(request, 'home.html', {'latest_images':latest_images})
On production environment using normal filesystem storage, ensure the webserver has permission to write to MEDIA_ROOT. Also configure the webserver to read /media/filename
from correct path.
ImageField() has an url
attribute so try:
<img src="{{ MEDIA_URL }}{{ image.image.url }}" />
You could also add a method to your model like this to skip the MEDIA_ROOT part:
from django.conf import settings
class Image(...):
...
def get_absolute_url(self):
return settings.MEDIA_URL+"%s" % self.image.url
Also I'd use upload_to like this for sanity:
models.ImageField(upload_to="appname/classname/fieldname")
Try these settings:
import socket
PROJECT_ROOT = path.dirname(path.abspath(__file__))
# Dynamic content is saved to here
MEDIA_ROOT = path.join(PROJECT_ROOT,'media')
if ".example.com" in socket.gethostname():
MEDIA_URL = 'http://www.example.com/media/'
else:
MEDIA_URL = '/media/'
# Static content is saved to here
STATIC_ROOT = path.join(PROJECT_ROOT,'static-root') # this folder is used to collect static files in production. not used in development
STATIC_URL = "/static/"
STATICFILES_DIRS = (
('', path.join(PROJECT_ROOT,'static')), #store site-specific media here.
)
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)
For Django version 2.2., try the following:
#You need to add the following into your urls.py
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
Your URL mapping
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) #add this
# And then use this in your html file to access the uploaded image
<img src="{{ object.image_field.url }}">
You have to make the folder containing the uploaded images "web accessible", ie either use Django to serve static files from the folder or use a dedicated web server for that.
Inside your template code, you have to use proper MEDIA_URL
values.
