Migration does object to DB creation:


python manage.py makemigrations
python manage.py sqlmigrate <package name> version number
ex python manage.py sqlmigrate travello 001
python manage.py migrate

Re-migration:

python manage.py makemigrations
python manage.py migrate

Admin Panel:

run the host and /admin
If operational error:
 python manage.py migrate

----------------------

You've locked yourself out, because you enabled md5 authentication for database user postgres without setting a password for the database user postgres.

Add a new line to the top of pg_hba.conf:

local    postgres     postgres     peer
then restart/reload PostgreSQL and:

sudo -u postgres psql
From the resulting prompt:

ALTER USER postgres PASSWORD 'my_postgres_password';


---------------------------
Creating a PostgreSQL Database
Step 1: Login as the Postgres User

su - postgres

Step 2: Enter the PostgreSQL Environment

psql

With the psql command, you’ll be greeted by its current version and command prompt.

psql (9.5.14)
Type "help" for help.
postgres=#

Step 3: Creating the PostgreSQL Database

Let’s create our first database by typing in the command below.  Replace dbname with the database name of your choice.

CREATE DATABASE dbname;

Open admin.py and 
admin.site.register(Destination)

Now u can see the space for entereing values to your DB


Working project : C:\Users\Admin\Python\Projects\telusko




---------------------------------

Part 1: Install the required packages
sudo apt-get install python-pip python-dev build-essential

sudo pip install virtualenv virtualenvwrapper

sudo pip install --upgrade pip

Part 2: Setup virtualenvwrapper in ~/.bashrc.
I used vim to edit ~/.bashrc.

Firstly, install vim with the command:

sudo apt-get install vim

Secondly, edit ~/.bashrc

vi .bashrc

enter [Shift] + [g] //G (shift + g): to go the end of the file

enter [a] //Type a to edit the file

export WORKON_HOME=~/virtualenvs

source /usr/local/bin/virtualenvwrapper.sh

enter [Esc] then :wq

The Esc key means return the command line, :wq means save the changes and exit vi.

Part 3: Enable the virtual environment.
source ~/.bashrc

mkdir -p $WORKON_HOME

Now, you can try again with mkvirtualenv:

mkvirtualenv your_project

To enable the 'your_project' virtual environment:

 workon your_project

To exit it:
deactivate

if any error try re installing : sudo apt install virtualenv
