    <p>This is the first project I've done using Class-based views in django (1.4) and I'm having some trouble with date-based archives not returning URLs. I've successfully built several apps in my project (a corporate intranet) that don't need them, but the 'news' part of the site really needs a date-based archive.</p> <p>The year, month and day archives all seem to work fine, but my individual articles aren't producing the URLs I think they should. I'm pretty sure the problem is in my get_absolute_url function in models.py, because if I type the URL I want them to have directly django finds and displays the article I want!</p> <p>Calling get_absolute_url function from a shell I get:</p> <pre><code>NoReverseMatch: Reverse for 'news_detail' with arguments '('2013', 'Jan', '14', 'another-news-thang')' and keyword arguments '{}' not found. </code></pre> <p>I've read the <a href="https://docs.djangoproject.com/en/1.4/topics/class-based-views/" rel="nofollow">relevant docs</a> and the specific reference for the <a href="https://docs.djangoproject.com/en/1.4/ref/class-based-views/#datedetailview" rel="nofollow">DateDetailView</a> but I can't quite get my head round where I'm going wrong.</p> <p>My models.py is:</p> <pre><code>from django.db import models import datetime from django.core.urlresolvers import reverse from django.contrib.auth.models import User from phone_list.models import Person, Team from tinymce import models as tinymce_models from taggit.managers import TaggableManager from easy_thumbnails.fields import ThumbnailerImageField class LiveNewsManager(models.Manager): def get_query_set(self): return super(LiveNewsManager, self).get_query_set().filter(status=self.model.LIVE_STATUS) class News(models.Model): LIVE_STATUS=1 DRAFT_STATUS=2 HIDDEN_STATUS=3 STATUS_CHOICES=( (LIVE_STATUS, 'Live'), (DRAFT_STATUS, 'Draft'), (HIDDEN_STATUS, 'Hidden'), ) # core fields headline=models.CharField(max_length=250) image = ThumbnailerImageField( upload_to='news_images', resize_source=dict(size=(700, 500), sharpen=True), null=True, blank=True, help_text = "Optional.

Any help much appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
