Hi, yes i was approaching it very wrong, but figured it out.
Here is a little test which i got to work with the help of some IRC
django people! (Thanks).
I didnt know that django would also send all the related items from
the intermediate table to the template. Very nice!
I guess I should do some filtering thou as this could be a lot of
data..
Using my "news", "imagegroup", "images" setup, this is how i get to
the "images" data from the news object.
Yes News as a name would be better but than admin made Newss out of
it ;), I forgot that you can define the plural some where in the
model.
This gets the 1st result:<br />
{{ new.imagegroup.all.0.image.caption }}
{% if new.imagegroup.all.0 %}
<br />This has images
{% else %}
<br />This has NO images
{% endif %}
<br />
This gets all results: <br />
{% for newsitem in new.imagegroup.all %}
<p>
{{ newsitem.createdate }}
<br />
{{ newsitem.position }}
<br />
{{ newsitem.image.caption }}
<br />
{{ newsitem.image.get_imagefile_url }}
</p>
{% endfor %}
