    <p>Hi I have a Django template tag to get an rss feed. It is quite simple and uses feedparser to place the decoded result in the context. IE</p> <pre><code>context[self.var_name] = feedparser.parse(self.url) </code></pre> <p>For a particular url '<a href="http://feeds.bbci.co.uk/news/england/oxford/rss.xml" rel="nofollow">http://feeds.bbci.co.uk/news/england/oxford/rss.xml</a>' The first entry printed from feedparser has an entry like this (I have removed other keys to keep this post short).</p> <pre><code>{'media_thumbnail': [{'url': u'_67862157_67862150.jpg', 'width': u'66', 'height': u'49'}, {'url': u'67862000/jpg/_67862158_67862150.jpg', 'width': u'144', 'height': u'81'}]} </code></pre> <p>However, in my template tag test the element 'media_thumbnail' is changed so the list is empty.</p> <p>My test case</p> <pre><code>class GetRssTagTest(TestCase): def test_request(self): t = Template('{% load rss_parser %}}{% get_rss "feed.xml" as rss %}{{rss.entries.0}}') c = Context({}) print t.render(c) </code></pre> <p>returns</p> <pre><code>{media_thumbnail&amp;#39;: u&amp;#39;&amp;#39;} </code></pre> <p>(Again have removed other fields)</p> <p>I can't understand why is element has been removed ? There are other lists in that dictionary that have been left.</p> <p>Is there some kind of key/size limit to what can be passed to a context variable ?</p> <p>I know I could make a tag custom and do this in Python but I would rather keep the tag generic for use with other feeds.</p> <p>Thanks</p>

    1. CONot that this makes a difference, but `{% load rss_parser %}}` has a trailing `}`. Also `{media_thumbnail&#39;: u&#39;&#39;}` looks incorrect to me - It should have been `{&#39;media_thumbnail&#39;: u&#39;&#39;}` . I m guessing there is a typo somewhere

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.
