When using the object_detail generic view:
If you have for examle a blog entry Entry(), and comments Comment() on it;
I would use this to loop for comments:
{{{
{% for comment in object.comment_set.all %}
{{ comment.body_text }}
<hr>
{% endfor%}
}}}
Now the problem is; it is impossible to display something in case there
are no comments without hitting the database again.
It could be fixed with an '{% elsefor %}' or by making it possible to
assign object.comment_set.all to some var once.
Another solution would be to make '{% if object.comment_set_all %}' create
a variable 'if.result' or something.
