How to connect to the PostgreSQL Database in Django

Hello everyone!!

In this article we are going to show you how to connect postgresql in django. PostgreSQL is a powerful and open source object relational database system. It has a wide range of uses and applications in the field of technology, also it has fast performance. Django has an SQLite3 database by default. PostgreSQL has the capability to handle the complex database. The integration of PostgreSQL with Django can improve production performance.

In this article you will learn how to connect a postgreSQL database to a django project. Also you will learn how to create a Virtual environment for a django project and how to edit your django project setting file and connect with postgreSQL database. So let's start.

Create Virtual Environment

First create an empty folder and open it in the visual studio. After creating the directory and opening it in the visual studio, create a virtual environment using “py -m venv env” command by selecting a new terminal. The final step is to activate the virtual environment. Then use ctrl + shift +p shortcut key and select python executable file from the folder just created by creating a virtual environment command.

Now open a new terminal. You will see that the virtual environment will be activated.

Installing Django and PostgreSQL

To install Django and postgreSQL just run the following command

  1. pip install django

  2. pip install psycopg2

Creating project and application in Django

Let's create our first project, which will only have one project in our project folder.

django-admin startproject postgresConn

As a result of the above command, the “postgreConn” project folder will be created in our project folder.

Now move the project folder using the following command.

cd postgreConn

Launch the application using the following command.

python startapp testdb

Now running the project to ensure that the out project is working correctly. Run the following command.

Python .\manage runserver

from django.shortcuts import render

# Create your views here.

# Create your views here.
def index(request):
    return render(request,"index.html")

Then create a new folder in testdb “templates”. In this folder contains all webpage related files html files.

    description = models.TextField()
    def __str__(self):
        return self.assignment 


from django.contrib import admin

from .models import Assignment

Now open pgadmin4. Create a database “test1"


By default the django uses sqlite3 database. Here we change the code and field the details of database name, user and password to connect with postgresql.

    'default': {
        'ENGINE': 'django.db.backends.postgresql',
       'NAME': 'test1',
       'USER': 'pushkar',
       'PASSWORD': 'pushkar',

Test Connection

Run the following command to migrate all tables in our Django project to PostgreSQL.

python .\ makemigrations
python .\ migrate

You will get the output as shown below.

Create Superuser

Just run this command to create superuser. field the details like username, email address and password.

python .\ createsuperuser

Now run the Django project

command : python .\ runserver

We go to on and Add the assignment and descriptions by clicking on add button.

After adding the you will see it on the home page.
