Django compressor issue - media assets from the forms.py won't update in the frontend django template

[Danny Blaker]

We are currently experiencing an issue with the Django compressor: We have 
an app that has forms.py and its media assets from the forms.py won't 
update in the frontend django template (only stuff inside the django 
compress tag won't update). This problem came about when we initially 
included external files in the static files media asset in forms.py, but 
that lead to problems with django compressor not being able to compress and 
access via our Cloudfront CDN. We changed that and now, it's stuck there, 
meaning it won't refresh with our newer local static files (we changed 
external file links to local static in the Media class inside forms.py). We 
have flushed our Redis node, done cloudfront invalidations, compressed 
again, collectstatic, terminated and started new instance within 
elasticbeanstalk. Has anyone had experience a similar issue and / or has 
any solutions? Many Thanks!!

Our architecture:
Elasticbeanstalk. (amazon's linux ec2 instance, python)
RDS (postgres database)
Elasticache (Redis)

Re: How to get object id from database?

[Yoo]

Maybe try album__id (two underscores)? Or try album_title as defined in the 
Album model. I also advise not to expose your primary key in the URL. If 
the above did not work, check Django  documentation: 
https://docs.djangoproject.com/en/2.2/topics/http/urls/

Re: Right method for url mapping

[Yoo]

First one. Usually I'd have it be views.index. Otherwise, the first one is 
perfectly fine. Need explanation?

Hostgator used to be a decent company until they were bought out by
EIG, a parent company with a reputation of buying up good hosting
companies and turning them into a bucket of suck.  They over allocate
their shared hosts, customer/technical service is slow and
inconvenient (they tend to shut down email and web case submission in
favor of chat, but then are slow to answer chats if at all; nagging
on Twitter will get a "please give us the case# and we'll escalate
it" which largely means they'll actually look at it)

I had service with one that got bought out by EIG and turned
horrible (and AFAICT, ended up going under as a business), so I fled
to another (Site5) which also got bought out by EIG and also turned
horrible. So I'd avoid any EIG property unless you don't care about
the quality of your hosting:

https://www.linux-depot.com/non-endurance-international-group-eig-hosting/

I have good things to say (from either personal experience or the
experiences of those I trust) about Digital Ocean, Heroku, Linode,
OVH, and Vultr.
