Re: Query Regarding Django Signals

2018-05-04 Thread jacob duyon 
You can also just write a Celery task to do your async stuff and trigger it
from signals.py

Re: Need Help With integrating Python Scripts with Django Frame Work

2018-04-16 Thread jacob duyon 
I'm not sure how many users you have for this, but it's best practice to
use an asynchronous task queue (like Celery) to run the actual powerpoint
creation code. If you simply run the script inside the view it will block
the response from happening. You create a celery task (which in your case
would have the powerpoint code), and the view will add the task to the
queue.

Celery requires a message broker, like RabbitMQ or Redis in order to use
it. They are both simple to setup and work well. The docs are pretty good
too.

Re: What were your best resources in learning programming, python, ultimately django?

2018-04-09 Thread jacob duyon 
Do the class completely. Don't skip anything, especially things that are
hard. Always try to figure something out on your own, and take breaks when
you are completely stuck. If you are ever stuck, ask yourself why you are
stuck, and usually its because you don't understand some dependency. Google
everything about that thing until you fully understand that well. Then,
come back to the problem. Getting stuck and persevering are the fastest
ways to learn something, so don't be fearful of that process.

Tango with Django is the first interactive book I've read for Django. I
started by making some silly website I was interested in as quickly as I
could. Then, I went back and rebuilt it by writing tests for everything.
When you are prototyping to see how something works, don't bother with unit
tests. When you are prototyping you want to get an idea of how to design
the code. Just make sure to re-build it while writing unit tests.

Learning how to test things is the most important thing to learn early on.
When you write tests for your project, you are not only testing that the
thing works.. but also are writing documentation about how to use it.
