    <p>I'm building some project with bottle and I need it to run certain scheduled actions periodically.</p> <p>I decided to go with rabbitmq + celery since that seemed like the most robust &amp; complete solution to manage scheduled works programatically.</p> <p>I installed both rabbitmq and celery okay, and when I use celeryd -B , tasks get done okay. However when I use celerybeat command, tasks are "sent" (or so says the output, cause I run both celeryd and celerybeat with -l debug option to be more verbose), but though they are regularly being "sent", they don't get executed (for testing purposes, task ought to appent current timestamp to a file every 60 sec). Anyway, everything else works fine since celeryd -B command in the same directory works just fine, it writes the file in expected intervals.</p> <p>Am I missing something?</p> <p>Here is the output of $celerybeat -l debug:</p> <pre><code>[2012-06-30 18:07:44,676: WARNING/MainProcess] celerybeat v2.5.5 is starting.

    1. COThanks for the attention to details, @Taras. Anyway, the answer to this, it seems is aparently that celerybeat needs parallel celeryd process to function. If anyone thinks its wrong, do add your answer.

    2. COYes that's correct - celerybeat schedules the tasks, which celerd then picks up and actually executes. Thanks for the follow up @toninoj

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).
