Django is a Python-based web framework that follows the MTV (Model-Template-View) design pattern. It allows developers to create dynamic websites and web applications by handling common tasks like database access, session management, and rendering templates. The document outlines how to create a Django project and app, configure settings like the database, and link views to URLs to handle requests and return responses.

What is Django? Django is a python-based web framework.
What is a framework? A web application framework (WAF) is a software framework that is designed to support the development of dynamic websites, web applications, web services and web resources.
The MTV Design  M-Models  T-Templates  V-View
Creating a Project Move to the directory where you want to create the project Type the following command in terminal C:/Python27/Scripts/django-admin.py startproject myprojectname Mysite/ manage.py mysite/ __init__.py settings.py urls.py wsgi.py
Settings.py  Databases DATABASES = { 'default': { 'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'. 'NAME': '', # Or path to database file if using sqlite3. 'USER': '', # Not used with sqlite3. 'PASSWORD': '', # Not used with sqlite3. 'HOST': '', # Set to empty string for localhost. Not used with sqlite3. 'PORT': '', # Set to empty string for default. Not used with sqlite3. } }
Settings.py (contd…)  Debug- is a boolean field and used to decide if your project is running on debug mode or not.
Creating an App  Move inside your project directory  Type the following in your terminal python manage.py startapp appname Your directory listing will look like books/ __init__.py admin.py models.py tests.py views.py
View  It is a python function that takes a request parameter as its first argument.  It always returns a response. from django.http import HttpResponse def hello(request): #Your code goes here return HttpResponse("Hello world")
URL(s)  It is used to link up your view to a URL(s) typed in the address bar.  It is a mapping between URL(s) and view functions that should be called for those URL(s) from django.conf.urls.defaults import patterns, include, url from mysite.views import hello urlpatterns = patterns('', url(r'^hello/$', hello), )
