    <p>For my current flask deployment, I had to set up a uwsgi server. This is how I have created the uwsgi daemon:</p> <p><code>sudo vim /etc/init/uwsgi.conf</code></p> <pre><code># file: /etc/init/uwsgi.conf description "uWSGI server" start on runlevel [2345] stop on runlevel [!2345] respawn exec /myproject/myproject-env/bin/uwsgi --uid www-data --gid www-data --home /myproject/myproject-env/site/F11/Engineering/ --socket /tmp/uwsgi.sock --chmod-socket --module F11 --callable app --pythonpath /myproject/myproject-env/site/F11/Engineering/ -H /myproject/myproject-env </code></pre> <p>However after running this successfully: <code>sudo start uwsgi</code></p> <pre><code>uwsgi start/running, process 1286 </code></pre> <p>And trying to access the application via browser:</p> <p>I get a <strong>502 Bad Gateway</strong></p> <p>and an error entry in nginx error.log:</p> <blockquote> <p>2013/06/13 23:47:28 [error] 743#0: *296 upstream prematurely closed connection while reading response header from upstream, client: xx.161.xx.228, server: myproject.com, request: "GET /show_records/2013/6 HTTP/1.1", upstream: "uwsgi://unix:///tmp/uwsgi.sock:", host: "myproject.com"</p> </blockquote> <p>But the sock file has the permission it needs:</p> <pre><code>srw-rw-rw- 1 www-data www-data 0 Jun 13 23:46 /tmp/uwsgi.sock </code></pre> <p>If I run the <code>exec</code> command from above in the command line as a process, it works perfectly fine. Why is the daemon not working correctly please?</p> <p>btw Nginx is running as <code>vim /etc/nginx/nginx.conf</code></p> <pre><code>user www-data; </code></pre> <p>and <code>vim /etc/nginx/sites-available/default</code></p> <pre><code>location / { uwsgi_pass unix:///tmp/uwsgi.sock; include uwsgi_params; } </code></pre> <p>and it is started as <code>sudo service nginx start</code></p> <p>I am running this on <code>Ubuntu 12.04 LTS</code>.</p> <p>I hope I have provided all the necessary data, hope someone can guide me into the right direction. Thanks.</p>

    2. CO@joe, Ubuntu 12.04 LTS that is. I just tested it on my laptop running 13.04 and its exactly the same problem. Which is good, hence replicable.

    3. COsounds like the daemon runs under a different user or has access to different configs... isn't this a hint: http://stackoverflow.com/questions/394984/best-practice-to-run-linux-service-as-a-different-user

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).
