Celery might overkill they are other more simple solutions that only
involve your current database and cron jobs.

Re: Django/Web Programming Pattern

2013-11-14 Thread Jonathan Baker

You're welcome. I just set celery+rabbitmq up on a new project, and while
it can seem like a lot of steps (and potential information overload), it
isn't so bad once you get a grasp on the concepts.

One thing that recently bit me: once in production with running workers, if
the models your task code are interacting with change (in my case, a south
migration from concrete inheritance to abstract), you need to restart the
workers just like you would Apache (doc:
http://docs.celeryproject.org/en/latest/userguide/workers.html#restarting-the-worker).
This seems obvious to me know, but hindsight...

I have a situation where I'm loading a lot of images that takes a long
time. What I do is I have this code in my template:

 ... loading images 

$('.loadMsg').show();

window.onload = function() {
$(function() {
$('.loadMsg').hide();
});
};

Not the most elegant thing in the world, but it works and meets my needs.
YMMV

This sounds like a good candidate for an async Celery task:

Django/Web Programming Pattern

2013-11-14 Thread Timothy W. Cook

Well, this isn't likely a Django specific question but since this
project is built in Django, I'd like to know how best to handle this
issue.

I have a view that calls a function and performs a long running
process.  It reads and processes a file, creating potentially
thousands of objects and can take up to several minutes to complete.

Right now it just displays a pretty much blank template.  This isn't
very user friendly.  I imagine some kind of counter or progress bar
but I am not certain how best to display this via Django.

What do others do in this case?

Thanks,
Tim
