Connecting Django to PostgreSQL database (GeoDjango)

I am having issues connecting to my Postgresql database with my Django website. My database is set up at Port 5434 as there is already an existing database in the default 5432 port.
This is the error I am getting

This is my settings.py file in django
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'database_name',
'USER': 'postgres',
'PASSWORD': '******',
'HOST': 'localhost',
'PORT': '5434',
}
}
Hi, I figured it out. Really stupid mistake. I add two of the Database= {} configuration twice, once at the top of the file and once i the bottom and for got to delete it lol.

This issue is generated for lack of permission.You should give the permission in pg_hba file.
Log into your db user and then play the command psql. The sequensial coammnd is given bellow.
sudo su - postgres
psql
show hba_file;
In my case the output is /var/lib/postgresql/data/pg_hba.conf. Rember this location
\q
ctrl + d # for loging out from postgres user
sudo vim /var/lib/postgresql/data/pg_hba.conf #you can use your prefer text editor
You need to change the file as shown bellow. Just change all method to trust.

django.db.utils.OperationalError: fe_sendauth: no password supplied when migrating django app

I'm a beginner with Django working on an open source project, which has been very challenging since it only gives build instructions for Mac, and not Linux. So, on my Ubuntu server, I've managed to install all the packages and fix a few initial bugs, but now, when I do python manage.py migrate, I'm stuck with this error: django.db.utils.OperationalError: fe_sendauth: no password supplied
I'm totally stuck here: I'm having a tough time understanding the error message, and other solutions aren't much help. Other solutions indicate that you have to change the DATABASES setting in the settings.py, but the setting has no PASSWORD attribute and it's only linked to sqlite:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
DATABASES['default'] = dj_database_url.config()
The error doesn't trace back to any specific lines of code so I'm guessing its more related to psycopg2 or django than the code itself, but I'm not sure how to go about fixing it. I'm using Python 2.7.17 and Ubuntu 18.04.5. Here's the full error message:

django.db.utils.OperationalError: fe_sendauth: no password supplied
Again, I'm very new to Django and Postgres, so I may be missing something obvious. It's equally likely that the code just doesn't work on Linux or that there's some unfixed bug in it. Any help would be appreciated.

As Vineet pointed out, the DATABASES['default'] = dj_database_url.config() line was overwriting the configuration, and as a result the 'PASSWORD' and other attributes existed and were blank. I added this line after it:
del DATABASES['default']['PASSWORD'], DATABASES['default']['HOST'], DATABASES['default']['PORT']
and the problem has been solved.

OperationalError: could not connect to server: Operation timed out - when trying to change database from sqlite to postresql

I'm following this tutorial to configure my zappa app so I can use AWS lambda functions for my django app. I'm up to "Configure the database" so that's what I'm trying to do. My django app uses postgresql so I'm trying to change my zappa app to postgresql (from the default sqlite). I've successfully created a postgres DB instance on Amazon RDS. The instance setting Publicly accessible is set to Yes.
I've also successfully installed psycopg2 and psycopg2-binary in my zappa app, as well as changing my DB settings:
DATABASES = {
'default': {
'ENGINE': config('DB_ENGINE'),
'NAME': config('DB_NAME'),
'USER': config('DB_USER'),
'PASSWORD': config('DB_PASSWORD'),
'HOST': config('DB_HOST'),
'PORT': '5432',
}
}
However when I perform makemigrations in my zappa app I get the following error:

Any idea what the problem is?

You need to open port 5432 on the aws firewall or on the box itself:
Here is a test on that port:

How to connect AWS RDS MySQL from Django app from local

SOLVED: Issue was using USERNAME, not USER.
I am able to connect to the RDS instance from both MySQL Workbench and the mysql CLI command, so it is not the credentials that are the issue. I am trying to run python manage.py migrate but I get the following output:

I've set the AWS Security Group and VPC Security Group with

I have the following in my settings.py

'PASSWORD': 'xxx',
'HOST': 'xxx.xxx.us-west-2.rds.amazonaws.com',

}
}
And this at the beginning of my manage.py
#!/usr/bin/env python
try:
import pymysql
pymysql.install_as_MySQLdb()
except ImportError:
print "Failed to import pymysql"
I'm just very confused since I can connect through mysql CLI, MySQL Workbench, and even through short python scripts like below.
connection = pymysql.connect(host='xxx.xx.us-west-2.rds.amazonaws.com',
user='xxx',
password='xxx',
db='playercomp',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)

Solution was to change USERNAME to USER.

I am new to programming and learning the web development. I have installed the

django.db.utils.OperationalError
I have checked with python script the psycopg2 is able to connect the database in postgresql but when I am running migrate from django project, its not working and getting above error.

Your postgres server is not started. You need to start the server first. Django does not come with postgres or any DB server. It provides connectors and ORM for these DB servers. Install postgres , create user and db as per your DATABASE settings in django, the errors should go.
If you dont know how to install postgres, then google.
Hope this helps.

You need to change 'User' to 'USER' in your DATABASES settings.
