1) how to install django
	apt-get install python-django

2) how to check whether your django is correctly working or not
	python -c "import django; print(django.get_version())"
	
	here python -c is used for executing the python command 
	c stands for "command"
	
3) creating your first django project
	django-admin.py startproject MyFirstProject
	
4) how to create your own development server
	cd MyFirstProject
	python manage.py runserver
	
	NOTE
		by default the server will be running on 127.0.0.1:8000
		
		if you want to change the port and ip 
			changing the port : python manage.py runserver 8080
		
			changing the ip : python manage.py runserver 127.2.2.2:8080
			
5) creating a new app called "polls"
	python manage.py startapp polls
	
6) Edit the polls/models.py file so it looks like this:

#############################
from django.db import models

# Create your models here.

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')


class Choice(models.Model):
    question = models.ForeignKey(Question)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)
#############################

7) Edit the mysite/settings.py file again, and change the INSTALLED_APPS setting to include the string 'polls'. So it’ll look like this:
	by this now Django knows to include the polls app
INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls',
)

8) To create sql tables
	python manage.py sql polls
9) Now, run syncdb again to create those model tables in your database:
	python manage.py syncdb
	
	
	
from polls.models import Question,Choice
Question.objects.all()
Question.objects.filter(id=1)
from django.utils import timezone
q=Question(question_text="How are you?",pub_date=timezone.now())
q.save() 															# saving into the database
q.question_text="What are you doing?"
q.save()
