Body
I'm using GAE Python 2.7 with the local development server. I have configured a backend <pre><code>backends: - name: worker class: B1 options: dynamic </code></pre> and I'm using the default taskqueue. Everything works fine and the backend and taskqueue are visible at the SDK console. Also the local development work starts without any errors: <pre><code>Multiprocess Setup Complete: Remote API Server [http://localhost:9200] App Instance [http://localhost:9000] Backend Instance: worker.0 [http://localhost:9100] Backend Balancer: worker [http://localhost:9199] </code></pre> BUT if I try to address the backend via a task <pre><code>taskqueue.add(url='/xyz', method='POST', target='worker', params={'a':'b'}) </code></pre> this error raises: <pre><code>ERROR An error occured while sending the task "task1" (Url: "/backend/languages/create_database/") in queue "default". Treating as a task error. Traceback (most recent call last): File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/taskqueue/taskqueue_stub.py", line 1884, in ExecuteTask connection.endheaders() File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 937, in endheaders self._send_output(message_body) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 797, in _send_output self.send(msg) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 759, in send self.connect() File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 740, in connect self.timeout, self.source_address) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 553, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): gaierror: [Errno 8] nodename nor servname provided, or not known </code></pre> I'm using 'localhost' and can't see any reason why it fails. Some ideas / solutions? Any startup-parameter missing or somethin like that? Thanks

Guidance

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.
