That's because of my example. I have a LEGO Set model:
class Set(models.Model):
lego_id = models.CharField(max_length=32, primary_key=True, blank=True)
#lego_id stores the unique number that's on every Lego box
text_name = models.CharField(max_length=64)
#...
And I resolved my problem by adding primary_key=True, like you said. (I
hope it's OK if the pk is a CharField?). Now the link works fine, and the
lego_id is the link, like so:
(r'^sets/(?P<pk>\d+)/$', SetDetailView.as_view(
model=Set,
context_object_name="set_details",
template_name='data/set_details.html',
)),
But the site is empty. Here's my extremely simple template:
{% block title %}{{ set.text_name }}{% endblock %}
{% block content %}
<h2>Set:</h2>
{{ set.theme }} - {{ set.subtheme }}
{% endblock %}
All I can see is the one " - " :).
