Django JSONField Constraint
I have a model that represents an email, which was sent via my Provider X. Im getting a callback from X with data, that I would like to save in the field called additional_recipients. Because of some mailing list only allowing 5 max additional recipients, i need to limit the jsonfield to only contain max 5 emails per row class EmailCallback(models.Model): additional_recipients = models.JSONField(default=list) Is it possible, to limit the JsonField so it it only holds max 5 values? [{"value": "email1"}, {"value": "email2"}, {"value": "email3"}, {"value": "email4"}] I know i can do class Meta: constraints = [ CheckConstraint(...) ] But i was wondering if thats even doable?

daemonizing celery worker and beat (environment variables problem or settings.py problem?)
I've been trying to daemonize celery and celerybeat using init scripts and systemd. The problem is that celery's tasks can't access rabbitmq and django database(postgresql in my case) because i moved my username and passwords to ~/.bashrc. for solving this problem celery documentation suggests: The daemonization script is configured by the file /etc/default/celeryd. This is a shell (sh) script where you can add environment variables like the configuration options below. To add real environment variables affecting the worker you must also export them (e.g., export DISPLAY=":0") Daemonization docs this gave me a hint to set variables in /etc/default/celeryd like this: export DJANGO_SETTINGS_MODULE="project.settings" export CELERY_BROKER_URL="ampq..." export DATABASE_USER="username" export DATABASE_PASSWORD="password" export REDIS_PASS="password" so after this, celery worker connects to rabbitmq virtualhost sometimes! most of the time it connects to rabbitmq as default guest user. before this it would always connect as guest user. when it connects as my user, worker and beat perform tasks without any problem. my tasks get and update objects from database and cache(redis). they work fine when i run them manually. I've read logs and it's always postgresql auth error by beat or the fact that worker is connected to rabbitmq as guest user. What is the solution … -

How to solve 'POST 401 Ajax Error' in the console of a deployed django website
I keep on getting an error like below in the chrome console whenever I click my "Place Order" button in my website. I have struggled with this for hours. Here is my error: POST https://{{mywebsitedomain}}/order/create_ajax/ 401 jquery-3.5.1.min.js:2 I have no idea why this error suddenly shows up after I uploaded my website on a hosting provider online.

Cannot deploy django app to strato hosting [closed]
Has anybody successfully deployed django app to strato (strato.de) web server? After some struggle I was able to install all dependencies as wall as npm and node. Basically I noticed that using strato with ssh is very limited. I am running gunicorn on my default wsgi file but when I try to reach my website from domain address, nothing happens. I noticed that there is apache installed on the machine but installing mod_wsgi via pip fails.
