Looks like you hit the same thing I did. What you want to do is test to
see if d is in supporters, so something like this:
{% for d in dreamers %}
<p>
<a href="/user/{{ dreamer.user }}">{{ d.user }}</a>
{% IfInList d in supporters %}
supporter
{% else % }
add me!
{% endif %}
</p>
{% endfor %}
Unfortunately, this doesn't exist yet in django, I added an
implementation of IfInList if you want a custom tag [1], or you can wait
for us to stop arguing about the right way to do it [2] and have it in
the regular if tag.
(Also, your href link should really be using {% url %} and should it
really be 'dreamer.user' and then 'd.user'?)
Cheers
