    <p>Keep in mind that a QuerySet is more than just a simple database query, so the "expected result" should be that it contains additional information. One simple way to do what you want (and I'd say it's a Django Way) is to define a <a href="https://docs.djangoproject.com/en/dev/topics/db/managers/" rel="nofollow">model manager</a> that returns only what you want. Something like:</p> <pre><code>import simplejson class StreamManager(models.Manager): def all_serialized(self): qset = super(StreamManager, self).get_query_set() return simplejson.dumps( [{ 'id':item.id, 'name':item.name, 'network':item.network.name, 'score':item.score, 'custom_url':item.custom_url,} for item in qset]) </code></pre> <p>then put <code>objects = StreamManger()</code> in your Stream class, and you can access the stream as Stream.objects.all_serialized()</p> <p>Another way to do it would be to subclass QuerySet so it returns only the information you want and then use the serialize() method on the queryset, but I've never gotten into that and assume it would require some knowledge of how QuerySets work under the hood (it might be slightly more efficient than my solution, but since the point is to serialize everything and you want to do a foreign key lookup on each entry to find the network name, I assume you not working with a huge amount of data).</p> <p>EDIT: regarding your comment on Rob's solution, see the <a href="https://docs.djangoproject.com/en/dev/topics/serialization/" rel="nofollow">documentation</a> for serialize() - you can define the fields you want to be serialized, but I don't think it supports foreign key lookups, and you'll still get it in the QuerySet format (pk, model, and fields).</p>

Querying!

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.
