Django database settings with PostgreSQL

By default, Django uses the SQLite database. For production applications, you can use the PostgreSQL, MariaDB, Oracle, or MySQL databases. For this book, it will be PostgreSQL. Perform the following steps:

1. The virtual environment is active; now, we will install the psycopg2 PostgreSQL adaptor with the help of the following command:

(venv) [root@ip-172-31-95-213 atmproject]# pip3 install psycopg2-binary

After the preceding command has been executed, the console should appear as follows:

2.  Now, open the settings file of the project to declare the database's RDS endpoint from AWS along with the username, password, and database name, as follows: 

(venv) [root@ip-172-31-95-213 atmproject]# vi atmproject/settings.py
