Django with Postgresql database createsuperuser no response - django

I've tried to use postgresql 10 database with django 2,
when i ran
python manage.py makemigrations
python manage.py migrate
the output indicates the database is doing well.
but when i try to create a supseruser
python manage.py createsuperuser
the console actually hangs like below:
root#ca80209360d2:/app# python manage.py createsuperuser
Username (leave blank to use 'root'): tdy
Email address:
Password:
Password (again):
so after i entered the passwords, it doesn't print out super user created successfully as when I'm using sqlite..
I have to Ctrl+C:

Connection error between Django and Postgres

I'm setting up an Amazon AWS test server with Django on which I use Postgres as a database. This was my way here:
$ sudo apt update
$ sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib
I downloaded my files from Github and created a virtual environment for it and inside I installed psycopg2.
$ pip install psycopg2
How I configured Postgres:
$ sudo -i -u postgres
$ psql
$ createuser --interactive (super user);
$ createdb Filme;
Some other information that may be useful about Postgres:
$ service postgresql status

PS: I also followed the DigitalOcean tutorial, but I end up falling into an almost identical error. (https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04)
You've only configured the ENGINE and NAME settings. You have left all the other DB connection settings as default, such as the username, password, etc. So it is trying to connect to the database using the username of the current Linux user, which appears to be ubuntu. I'm guessing when you ran createuser you didn't specify a username of ubuntu and you didn't leave the password blank, so you need to set those settings in the Django database config.
Look at all those database connection settings in the Digital Ocean tutorial you linked, compared to the two settings you have configured in your settings file.
Note that since you are just running Django and Postgres on the same server, there is nothing AWS specific about your issue. It is the same as how you would configure Django/PostgreSQL on any other Linux server. If you are searching for "django connect to postgres on AWS" or something like that, (focusing on the AWS aspect of your problem, when in actuality there is no AWS aspect to your problem at all), that is probably preventing you from finding answers to your question.

Gunicorn not starting anymore after adding PostgreSQL in Docker

I have a Django project that I'm trying to dockerize. I successfully added Django with gunicorn and nginx to Docker. However, when trying to add PostgreSQL, I encountered an issue. My Postgres container starts, but my gunicorn one doesn't start anymore, and I get this error in the logs, so it indeed seems like it comes from Postgres :

I tried changing the host IP address of postgres in my settings, but it only changed the error, but didn't solve it.

I have absolutely no idea where the problem could be coming from, so I'd be glad if someone could guide me on how to solve it, thank you in advance !

AWS Postgresql RDS instance "does not exist" with docker-compose and Django

My RDS and web container are not connected.
But I did all the database-related settings in Django's settings, and I also set up AWS RDS properly.
What should I do more?
This is DATABASES of settings file of Django.
DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
"NAME": env("SQL_DATABASE"),
"USER": env("SQL_USER"),
"PASSWORD": env("SQL_PASSWORD"),
"HOST": env("SQL_HOST"),
"PORT": env("SQL_PORT"),
}
}
I skipped the docker-compose.yml with nginx-proxy or TLS.
When I tested in local, I made and mounted DB containers on docker-compose, but in prod environments, I didn't make DB containers because I use AWS RDS.
Will this be a problem?
Please help me.

Highly likely the reason is that the AWS RDS DB instance name differs from PostgreSQL DB name.
As per AWS RDS manual
For Databases, choose the name of the new DB instance.
On the RDS console, the details for the new DB instance appear. The DB instance has a status of creating until the DB instance is created and ready for use. When the state changes to available, you can connect to the DB instance. Depending on the DB instance class and storage allocated, it can take several minutes for the new instance to be available.
As per PostgreSQL: Documentation
dbname
Specifies the name of the database to be created. The name must be unique among all PostgreSQL databases in this cluster. The default is to create a database with the same name as the current system user.
Default dbname is postgres
So, you may want to try postgres instead db-PROJECT_NAME-ec2 as a DB name.

How to solve pg_dump: aborting because of server version mismatch using docker

pg_dump: aborting because of server version mismatch
After searching for answers, I tried to update postgresql-client but it says I already have the newest version.
root#528fdf5ac614:/code/mysite# apt-get install postgresql-client
Reading package lists... Done
Building dependency tree
Reading state information... Done
postgresql-client is already the newest version (11+200+deb10u4).
0 upgraded, 0 newly installed, 0 to remove and 18 not upgraded.
So I don't know how to proceed. Should I downgrade the database container using postgres:11.12 docker image? That means data will be lost?
Also, why does the error say dbbackup.db.exceptions.CommandConnectorError: Error running: pg_dump --host=pgdb --port=5432 --username=postgres --no-password --clean postgres ?
I have set the password in base.py like so:

Your error is self-explanatory
pg_dump: server version: 13.3 (Debian 13.3-1.pgdg100+1); pg_dump version: 11.12 (Debian 11.12-0+deb10u1)
You should find psql as well as pg_dump for this installation under /postgres/bin/. This is the pg_dump you want to use. You can validate the version of pg_dump using
pg_dump --version
django-dbbackup allows you to specify the connector it uses to create the backup. In particular, it allows you to specify the dump command (DUMP_CMD). To specify the connector, add the following block to your settings.py:
import os # if not yet imported
DBBACKUP_CONNECTORS = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'xxx',

Celery can't connect to local PostgreSQL from within Docker container

I have a Django-Celery-PostgreSQL project that should partially run in Docker. Having Redis and PostgreSQL servers running locally on the machine and using virtual environment for the project everything runs smoothly. But when I try to setup Docker instance Celery seems unable to connect to the Postgres database while Django can.
When running project in Docker I put only Django and Celery in it and set network_mode: "host". Redis and Postgres remains on the local machine. Django server itself works flawlessly reading and writing data into the Postgres database, but when I try to run Celery tasks - I get following exception (thrown by django_celery_results):
[2019-08-13 11:26:24,815: ERROR/MainProcess] Pool callback raised exception: OperationalError('could not connect to server: No such file or directory\n\tIs the server running locally and accepting\n\tconnections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?\n',)

The above exception was the direct cause of the following exception:

Turned out I messed up with the DJANGO_SETTINGS_MODULE in celery.py - Celery got common settings file and not the one intended for the local development.
