DetailView not showing data

I am trying to display a ListView of items that when clicked opens the respective DetailView for that item. This is a pretty straightforward thing to do in Django, but I'm running into some trouble with it.

I have successfully created a ListView, but I can't get the DetailView to display the information for each item.

I am building a password safe. The ListView lists all the passwords saved, and the DetailView is the view/edit page for each password. And yes, I realize actually putting a password safe on the internet is a terrible idea, it's just a test project :)

My PasswordSafe class:

class PasswordSafe(models.Model):
    user = models.OneToOneField(User)

    pwWebsite = models.CharField(max_length=30)
    pwUsername = models.CharField(max_length=30)
    pwEmail = models.CharField(max_length=30)
    pwPassword = models.CharField(max_length=30)

    def __unicode__(self):              # __unicode__ on Python 2, __str__ on Python 3
        return self.pwWebsite

User.passwordSafe = property(lambda u: PasswordSafe.objects.get_or_create(user=u)[0])

My urls.py:

from django.conf.urls import patterns, include, url
from django.views.generic import ListView, DetailView
from models import PasswordSafe

urlpatterns = [
    url(r'^passwordSafe/$', ListView.as_view(queryset=PasswordSafe.objects.all().order_by('-pwWebsite')[:10], template_name = 'userprofile/passwordSafe_list.html')),
    url(r'^passwordSafe/(?P<pk>\d+)/$', DetailView.as_view(model=PasswordSafe, template_name='userprofile/passwordSafe.html')),
    ]

I use the following code successfully in my ListView template (passwordSafe_list.html):

{% for passwordSafe in object_list %}

    <h2><a href="/accounts/passwordSafe/{{passwordSafe.id}}">{{ passwordSafe.pwWebsite }}</a></h2>

{% endfor %}

However, when I try to use the passwordSafe data in my Detailview (the passwordSafe.html template), nothing shows up. I use the following code to try and change the title:

<title>{% block title %} | Edit {{ passwordSafe.pwWebsite }} Password{% endblock %}</title>

This should show a title something like "Password Safe | Edit Google Password", but passwordSafe.pwWebsite returns with nothing. Am I doing something wrong in trying to reference passwordSafe from this template? I know I haven't passed a query set like I did with the ListView, but I'm not sure if that's part of the problem or not.

In the DetailView, Django uses the model name in lowercase, by default, if you haven't set context_object_name. 

{{ passwordsafe.pwWebsite }}
