Django not displaying images from blog Post - django

Question

I have created a DJANGO blog-engine which takes my post and the template parses it for html tags. links etc.. are working but it does not load image file and instead shows the 'alternative' . I have tried the tag in separate html files and it is otherwise. Just not displaying image from inside a django blog post.
Relevant portions of the template file :
{% include 'blog/header.html' %}
</aside>
<section id ="content">
<article>
{%for post in posts %}
<h2>{{ post.title }}</h2>
<h3>{{ post.created}}</h3>
<p>
{{ post.body|safe }}<br>
</p>
<h3>By {{ post.author }}</h3>
I am copy-pasting the post in question
<---- text here ------------------>
GDCM::Directory
<img src="/home/usman/www/deejay/blog/static/images/dicomdir.png" />
This is it
Interestingly, the 'a' tag works fine but the 'img' tag is not working. I have tried many variations but i want some inline code to display simple html tag, alternatively of course i will resort to it programmatically by passing some variable to the template from inside the post to let it know where to position the image.

Answer 1

Your problem is here: {{ post_get_absolute_url }}. You should use {{ post.get_absolute_url }}.
The better way is to call the URL of the image directly; that way you maintain your URLs in urls.py and not in your model code. It makes your app more portable.
Take your image field name value from your model, and then {{ post.image.url }}. For example, if your model is:
class Post(models.Model):
img = models.ImageField(upload_to='images')
Then you would use {{ post.img.url }}

Answer 2

Problem solved when I replaced the full address with
<img src="/static/images/dicomdir.png"/>
On development server as well as on production. What helped was that I looked at the Dev-server responses on my terminal and was able to figure out the url.
