    <p>I am doing some file aggregation / generation and want to immediately run collectstatic afterwards. Ideally I either extend the collectstatic command (i don't know if this is possible) or I chain control to that command. I have tried the second, which isnt working:</p> <pre><code>class Command(BaseCommand): can_import_settings = True def handle(self, *args, **options): something_necessary() execute_from_command_line('collectstatic') </code></pre> <p>Many thanks in advance from this django newbie.</p> <p>Edit running from the command line is interesting</p> <pre><code>C:\www\app&gt;python manage.py customCmd ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb' </code></pre> <p>Well OK - that is interesting, as my command doesn't use the MySQLdb. But trying the collectstatic separately works:</p> <pre><code>C:\www\app&gt;python manage.py collectstatic C:\Python33\lib\site-packages\django\contrib\staticfiles\management\commands\collectstatic.py:65: DeprecationWarning: stat_float_times() is deprecated os.stat_float_times(False) You have requested to collect static files at the destination location as specified in your settings. This will overwrite existing files! Are you sure you want to do this? </code></pre> <p>If I write the command as simple as</p> <pre><code>from django.core.management.base import BaseCommand class Command(BaseCommand): can_import_settings = False def handle(self, *args, **options): pass </code></pre> <p>I get the MySQLdb error from a command line run. </p> <p>SO what I know </p> <ol> <li>it works fine from PyCHarm IF i dont make the call to execute_from_command_line</li> <li>I can't get my custom command to execute from the command line (python manage,py customCmd)</li> <li>the collectstatic works fine from both the PyCHarm interface and the command line</li> </ol>

    2. COIn pycharm it just kind of hangs, and I need to stop the command. if I remove the last line it works fine. I am trying to figure out the best way to run it separately from the console.

    3. COHmmm by saying it hangs, I'm wondering if you're inadvertently getting stuck in an endless loop - perhaps with control flow or (more likely?) through imports. Django's a little touchy re: databases. I've got a website which doesn't use a DB and it was a lot of hassle to unpick it. Make sure that your `settings.py` has `DATABASES = {}` if you're not using a DB, otherwise django will try to load drivers anyway.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
