Question

I’m on my first Django blog and when trying to get the posts by year, month and day, using the built-in generic view from Django, but I don’t get proper results. (Sorry for my non-professional first question.. if someone knows what is the appropriate question, please let me know)

Well, I think it’s better to show you my configuration to make yourself a better picture:

Complete blog URLconf:

from django.conf.urls.defaults import *

from weblog.models import Entry

entry_info_dict = {
    'queryset': Entry.published,
    'date_field': 'pub_date',
    'template_object_name': 'Entry',
    }

urlpatterns = patterns('django.views.generic.date_based',
      (r'^$', 'archive_index', entry_info_dict, 'weblog_entry_archive_index'),
      (r'^(?P<year>\d{4})/$',
       'archive_year', entry_info_dict,
       'weblog_entry_archive_year'),
      (r'^(?P<year>\d{4})/(?P<month>\w{3})/$',
       'archive_month',
       entry_info_dict,
       'weblog_entry_archive_month'),
      (r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/$',
       'archive_day',
       entry_info_dict,
       'weblog_entry_archive_day'),
      (r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/(?P<slug>[-\w]+)/$',
       'object_detail',
       entry_info_dict,
       'weblog_entry_detail'),
)

urls.py:

urlpatterns = patterns('',
(r'^blog/', include('weblog.urls.entries')),
...
)

entry_archive_year.html:

            <h2>Archive for {{ year }}</h2>
            <ul>
                    {% for month in pub_date %}
                    <li>
                            <a href="/blog/{{ year }}/{{ month|date:"b" }}/">{{ month|date:"F" }}</a>
                    </li>
                    {% endfor %}
            </ul>

Supposing I have the following blog entry:

example.com/blog/2009/dec/18/test

and now request

example.com/blog/2009/

I get no objects, though when giving the full URL the post is shown.

I think Django is failing silently somewhere, though it’s in DEBUG mode, and I can’t figure out where.
I’d appreciate any support with this one.

The month information is stored in the context variable date_list, not pub_date.

From the django docs for archive_year:

Template context:

In addition to extra_context, the
template’s context will be:

• date_list: A list of datetime.date objects representing all
  months that have objects available in
  the given year, according to queryset,
  in ascending order.

The following should do the trick:

{% for month in date_list %}
    <li>
        <a href="/blog/{{ year }}/{{ month|date:"b" }}/">{{ month|date:"F" }}</a>
    </li>
{% endfor %}
