Minor code error in doc page for DetailView

[ijl20@…]

Re:
​https://docs.djangoproject.com/en/dev/ref/class-based-views/generic-display/#django.views.generic.detail.DetailView

Current (2013-July-11) docs give example myapp/article_detail.html:

<h1>{{ object.headline }}</h1>
<p>{{ object.content }}</p>
<p>Reporter: {{ object.reporter }}</p>
<p>Published: {{ object.pub_date|date }}</p>
<p>Date: {{ object.now|date }}</p>

the last line should be

<p>Date: {{ now|date }}</p>

Because views.py only adds 'now' to the context, not as a new attribute of the object being rendered, as below. Currently, object.now displays as 'blank'.

    def get_context_data(self, **kwargs):
        context = super(ArticleDetailView, self).get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context
