How to get the public channel URL from YouTubeVideoFeed object using the YouTube API? | 776,110 | <p>I'm using the Python version of the YouTube API to get a YouTubeVideoFeed object using the following URL:</p>

<p>You have to get the link array from the feed and iterate to find alternate, then grab the href</p>

Appengine - Possible to get an entity using only key string without model name? | 776,324 | <p>I want to be able to have a view that will act upon a number of different types of objects</p>
<p>all the view will get is the key string eg:</p>
<p>agpwb2xsdGhyZWFkchULEg9wb2xsY29yZV9hbnN3ZXIYAww</p>
<p>without knowing the model type, is it possible to retrieve the entity from just that key string?</p>
<p>thank... | 3 | 2009-04-22T09:15:04Z | 776,332 | <p>If you design your models so they all use a common superclass it should be possible to retrieve your objects by using something like:</p>
<pre><code>entity = CommonSuperclass.get('agpwb2xsdGhyZWFkchULEg9wb2xsY29yZV9hbnN3ZXIYAww')
</code></pre>
