Also check the permissions on your images. I had set the
FILE_UPLOAD_PERMISSIONS to 0640 in development, but this wasn't
correct for my production server. Ensure that Apache or whatever user
the webserver is running has read access to your images.

First verify that the generated url is correct, that django is producing the 
right url with the context.  Then it would now be a problem of the image not 
being were you expect it or a misconfiguration of your urls.py.  I would 
suspect the latter first, so you need to check that.  For this, depending on 
your setup, you'll want to look at setting up django serve static files[1]. 
If you're using apache, you should follow the mod_python instructions [2]. 
For a seperate media server (url points to another domain such as 
media.yourdomain.com), then you should have your MEDIA_ROOT pointed to that 
domains document root.  

If this doesn't help and you are serving your media correctly, then you'll 
want to check your paths and make sure the actual file exists on the file 
system, where it should be.  

If all this is correct and you can view the image by itself in your browser, 
then follow the path of the earlier suggestions.

This will add the media url that you set for MEDIA_URL in settings.py (as long 
as the context processor for media is also set) 

an example of mine:

TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n", 
"django.core.context_processors.media",
}


As long as the url generated points to the image, this should work.

Ok!

views.py

from booksite.books.models import Article
from django.template import RequestContext

def art(request):
art = Article.objects.all()
return render_to_response('art.html', {'art': art},
context_instance=RequestContext(request))


art.html

{% for art in art %}
{{ art.title }}
{{art.anonce }}
 

{% endfor %}



I have made by your example, but all the same image is not displayed

It's not mentioned in the settings.py file, but that's why django has great 
documentation available for it.  See the link I posted before on how to use 
the context processors.  If you scroll up a little bit, the same page will 
show you how to use the RequestContext class to your benefit.

In my case I use the render_to_response shortcut in my views and pass the 
context_instance variable set as such: 

context_instance=RequestContext(request)

Full use is 

sample from views.py

from sample.models import News

from django.template import RequestContext

def index(request):
qs = News.objects.all()[:5]
return render_to_response('index.html', 
   {'items': qs},
   context_instance=RequestContext(request)
)

Doing so, django will apply the context processors to your request object, 
adding the contexts for use in your views.

I'm going to make a small suggestion, while the books are a great resource, 
they should be used in addition to the actual documentation available, not 
instead of.  

Mike.

In your settings.py check the context processors and make sure the 
Media context processor[1] is set and you pass the request object to your 
RequestContext[2]

art.allow_tags = True

I so have written, but all the same it is impossible

It can is necessary to make, that the path was http://127.0.0.1:8000/media/1.jpg

I think this line should be more along the lines of:



When you render the html, view the source, and make sure its rendering  
the right path.
Access the image directly through the browser to make sure you have  
the path correct.

Hope that helps,

Pawel.

Re: Question IMAGE in Django

[Vlad(L)]

Nick, thanks!
But I unfortunately cannot still make.
My problem: that in the Template the picture was displayed
For example, I load in Django Admin article, I write title, anonce,
body and I load Image... It is necessary For me, that Image it was
deduced on a site together with title, anonce, body

My new code:

settings.py

MEDIA_ROOT = 'C:/booksite/media/'
MEDIA_URL = 'http://127.0.0.1:8000/media'

models.py

class Article(models.Model):
title = models.CharField(max_length=200)
anonce = models.TextField()
body = models.TextField()
url = models.URLField(unique=True)
date = models.DateTimeField()
image = models.ImageField(upload_to='media/')

views.py


def art(request):
art = Article.objects.all()
return render_to_response('art.html', {'art': art})

art.html

{% for art in art %}
{{ art.title }}
{{art.anonce }}
 






urls.py

urlpatterns = patterns('',
('^$', index),
(r'^books/$', archive),
(r'^pub/$', publisher),
(r'^article/$', art),
(r'^admin/(.*)', admin.site.root),



)

For some reason for me title, anonce are output well, and image it is
not output - there an empty square with a red dagger in a browser...

Your question isn't very clear but I'll try and help with what it  
sounds like you're asking: How to get images into your template? If so  
how about something like this:

In booksite/books/templates/pub.html

{% extends "base.html" %}

{% block title %}Книги{% endblock %}
{% block banner %}{% endblock %}
{% block content %}
{% for x in pub %}
{{ x.name }}
 {{ x.address }}
 {{ x.website }}


{% endfor %}
{% endblock %}

Or you could use:

/images/pub/{{ x.id }}-thumbnail.jpg

Hope that helps?

Nick
