    <p>So, I've been noodling about with Django's generic views, specifically the <code>object_list</code> view. I have this in my <code>urls.py</code>:</p> <pre><code>from django.conf.urls.defaults import * from django.views.generic import list_detail from diplomacy.engine.models import Game game_info = { "queryset": Game.objects.filter(state__in=('A', 'P')), "template_object_name": "game", } urlpatterns = patterns('', (r'^$', list_detail.object_list, game_info), ) </code></pre> <p>and this fairly rough template that it is going to:</p> <pre><code>{% block content %} &lt;table&gt; &lt;tr&gt; &lt;th&gt;Name&lt;/th&gt; &lt;th&gt;Turn&lt;/th&gt; &lt;th&gt;Last Generated&lt;/th&gt; &lt;/tr&gt; {% for game in game_list %} &lt;tr&gt; &lt;td&gt;{{ game.name }}&lt;/td&gt; &lt;/tr&gt; {% endfor %} &lt;/table&gt; {% endblock %} </code></pre> <p>What I'm looking for is the best idiomatic way of including in this view the unicode representation and <code>generated</code> field (a <code>DateTimeField</code>) from the <em>most recent</em> <code>Turn</code> that points to the current <code>Game</code> in the loop, based on the value of <code>generated</code>. <code>Turn.game</code> is the field that points to the <code>Game</code> the turn belongs to (a <code>ForeignKey</code>).</p> <p><strong>Update:</strong></p> <p>My <code>Turn</code> model is as follows:</p> <pre><code>SEASON_CHOICES = ( ('S', 'Spring'), ('SR', 'Spring Retreat'), ('F', 'Fall'), ('FR', 'Fall Retreat'), ('FB', 'Fall Build') ) class Turn(models.Model): game = models.ForeignKey(Game) year = models.PositiveIntegerField() season = models.CharField(max_length=2, choices=SEASON_CHOICES) generated = models.DateTimeField(auto_now_add=True) def __unicode__(self): return "%s %s" % (self.season, self.year) </code></pre> <p>The <code>Game</code> model has not appreciably changed from the way I specified it in <a href="https://stackoverflow.com/questions/1197674/actions-triggered-by-field-change-in-django">this other question</a>.</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.
