    <p>I'm currently porting my GAE app to Python 2.7 and have come across some exciting things that I've slowly been able to figure out one at a time (Hello, aliased simplejson library!). However, I'm currently at a loss to explain this particular issue.</p> <p>Whenever I navigate to the Admin Console (http://localhost:8080/_ah/admin), I get a 404 page. This is strange in itself (This was working just fine before), but it also isn't my custom 404 page. This makes me think this is based on the built-in handlers, but I'm not sure what could be the cause.</p> <p>Other fun facts:</p> <ul> <li>There's no attempts to handle /_ah/.* in my app.yaml or elsewhere</li> <li>Nothing has changed in my app.yaml aside from the usual script-to-WSGI handler stuff</li> <li>No usage of Federated Logins</li> <li>Over time I've turned on almost all of the builtins</li> <li>The app deploys correctly and without issue</li> <li>I'm using the GAE Launcher on OSX (Minor, but it does have some odd quirks about it)</li> </ul> <p><em>Update</em></p> <p>It's probably easier just to show the console logs of what is coming out. This is after the app has fully started and I have attempted to navigate to the admin page twice (The IO Error is cute, and only happens the initial time):</p> <pre><code>[Master] [dev_appserver_multiprocess.py:650] INFO Running application mygaeapp on port 8081: http://localhost:8081 [Master] [dev_appserver_multiprocess.py:652] INFO Admin console is available at: http://localhost:8081/_ah/admin [Master] [dev_appserver_multiprocess.py:901] DEBUG balancer to port 9000 [App Instance] [0] [py_zipimport.py:139] WARNING Can't open zipfile /Library/Python/2.7/site-packages/slimmer-0.1.30-py2.7.egg: IOError: [Errno 13] file not accessible: '/Library/Python/2.7/site-packages/slimmer-0.1.30-py2.7.egg' [App Instance] [0] [py_zipimport.py:139] WARNING Can't open zipfile /Library/Python/2.7/site-packages/NoseGAE-0.2.0-py2.7.egg: IOError: [Errno 13] file not accessible: '/Library/Python/2.7/site-packages/NoseGAE-0.2.0-py2.7.egg' [App Instance] [0] [recording.py:372] INFO Saved; key: __appstats__:012400, part: 67 bytes, full: 8780 bytes, overhead: 0.000 + 0.007; link: http://localhost:8081/_ah/stats/details?time=1331638312442 [App Instance] [0] [dev_appserver.py:2865] INFO "GET /_ah/admin HTTP/1.1" 404 - [Master] [dev_appserver_multiprocess.py:901] DEBUG balancer to port 9000 [App Instance] [0] [recording.py:372] INFO Saved; key: __appstats__:020100, part: 67 bytes, full: 9196 bytes, overhead: 0.000 + 0.007; link: http://localhost:8081/_ah/stats/details?time=1331638320129 [App Instance] [0] [dev_appserver.py:2865] INFO "GET /_ah/admin HTTP/1.1" 404 - [Master] [dev_appserver_multiprocess.py:901] DEBUG balancer to port 9000 </code></pre>

    1. COIs the server logging the /_ah/admin request that's failing? I assume other requests to the app on that port are succeeding?

    2. COYes, but not as a 404. It's indistinguishable from any other successful page. Other requests on the port do succeed. Our 404 handler is pretty distinct as it logs information at an exception level as part of the page render.

    3. COThe _ah/admin uses the django template library. Do you have any references to django in your app? I've seen some people report errors, often from having the wrong version of django set up.

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).
