problem in using the address stored in imagefield
this is the news.html:
<html>
<head>
<title>News</title>
</head>
<body>
{% if news_list %}
<ul>
{% for news in news_list %}
<li><img src="{{ STATIC_URL }}/{{ news.image }}" width="100" height="100" />{{ news.image }} || {{ news.news }}</li>
{% endfor %}
</ul>
{% endif %}
</body>
</html>
this is the views:
from django.shortcuts import render_to_response
from news.models import MainNews
def display_news(request):
news_list=MainNews.objects.all().order_by('-date')
return render_to_response('news/news.html',{'news_list':news_list})
this is the models.py:
from django.db import models
class MainNews(models.Model):
news=models.CharField(max_length=200)
date=models.DateTimeField('date published')
image=models.ImageField(upload_to='news')
this is the news.html:
<html>
<head>
<title>News</title>
</head>
<body>
{% if news_list %}
<ul>
{% for news in news_list %}
<li><img src="{{ STATIC_URL }}/{{ news.image }}" width="100" height="100" />{{ news.image }} || {{ news.news }}</li>
{% endfor %}
</ul>
{% endif %}
</body>
</html>
this is the views:
from django.shortcuts import render_to_response
from news.models import MainNews
def display_news(request):
news_list=MainNews.objects.all().order_by('-date')
return render_to_response('news/news.html',{'news_list':news_list})
this is the models.py:
from django.db import models
class MainNews(models.Model):
news=models.CharField(max_length=200)
date=models.DateTimeField('date published')
image=models.ImageField(upload_to='news')

There can be better solutions but you can some easy hack like this -
date=models.DateTimeField('date published')
In models.py you can add a function to get image url
######################################
from django.db import models
import os
import settings
class MainNews(models.Model):
news=models.CharField(max_length=200)date=models.DateTimeField('date published')
image=models.ImageField(upload_to='news')
def get_image_url(self):
return os.path.join(settings.STATIC_URL, 'news', self.image.name.split('/')[-1])
######################################
now in the template make changes like this
<html>
<head>
<title>News</title>
</head>
<body>
{% if news_list %}
<ul>
{% for news in news_list %}
<head>
<title>News</title>
</head>
<body>
{% if news_list %}
<ul>
{% for news in news_list %}
<li><img src=" {{ news.image.get_image_url }}" width="100" height="100" />{{ news.image }} || {{ news.news }}</li>

you should describe your problem a little better!
But I guess the URL is not working?
You shouldn’t use STATIC_URL but MEDIA_URL for the prefix in your template.
STATIC_URL is for static files, that don’t change like CSS and JS.
MEDIA_URL is for user uploads, like a photo in your news entry.

yes even in get_image_url it will be
return os.path.join(settings.MEDIA_URL, 'news', self.image.name.split('/')[-1])

writing that function is not necessary.
3) All that will be stored in your database is a path to the file (relative to MEDIA_ROOT). You'll most likely want to use the convenience url function provided by Django. For example, if your ImageField is called mug_shot, you can get the absolute path to your image in a template with {{ object.mug_shot.url }}.
so the Pulkit was trying in his template is ok, he just should use the url function and the MEDIA_URL
