How to set up a PostgreSQL database in Django

Also make sure you have the PostgreSQL development package installed. On Ubuntu you need to do something like this:

$ sudo apt-get install libpq-dev

Step by step that I use:

 - sudo apt-get install python-dev
 - sudo apt-get install postgresql-server-dev-9.1
 - sudo apt-get install python-psycopg2 - Or sudo pip install psycopg2

You may want to install a graphic tool to manage your databases, for that you can do:

sudo apt-get install postgresql pgadmin4 

After, you must change Postgre user password, then do:

 - sudo su
 - su postgres -c psql postgres
 - ALTER USER postgres WITH PASSWORD 'YourPassWordHere';
 - \q

On your settings.py file you do:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'dbname',
        'USER': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': '',
        'PORT': '',
    }
}

Extra:

If you want to create the db using the command line you can just do:

- sudo su
- su postgres -c psql postgres
- CREATE DATABASE dbname;
- CREATE USER djangouser WITH ENCRYPTED PASSWORD 'myPasswordHere';
- GRANT ALL PRIVILEGES ON DATABASE dbname TO djangouser;

On your settings.py file you do:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'dbname',
        'USER': 'djangouser',
        'PASSWORD': 'myPasswordHere',
        'HOST': '',
        'PORT': '',
    }
}

You need to install psycopg2 Python library.

Installation

---

Download http://initd.org/psycopg/, then install it under Python PATH

After downloading, easily extract the tarball and:

$ python setup.py install

Or if you wish, install it by either easy_install or pip.

^{(I prefer to use pip over easy_install for no reason.)}

• $ easy_install psycopg2
• $ pip install psycopg2

Configuration

---

in settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'db_name',                      
        'USER': 'db_user',
        'PASSWORD': 'db_user_password',
        'HOST': '',
        'PORT': 'db_port_number',
    }
}
