Hello World!
-
Create a new web project called
sigcse
. We will use this project for all other examples. Type at the command line:django-admin.py startproject sigcse
This creates a new folder named
sigcse
. Change to that directory with the following command line:cd sigcse
This folder should contain the following four files:
File Name Description __init__.py
Used to indicate that the current folder is a Python package. manage.py
Utility script that allows you to interact with the current Django project in various ways. settings.py
Configuration file for this Django project. urls.py
The URL mappings for this Django project. -
Run the web server to see if it works correctly. Type at the command line:
python manage.py runserver
Now, visit
http://localhost:8000/
with your Web browser. You should see a welcome page. -
Create a
templates
folder. At the command line type:mkdir templates
-
Tell Django the location of your
templates
folder. Edit the
sigcse/settings.py
file. Add a line similar to the one being highlighted:TEMPLATE_DIRS = ( # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates". # Always use forward slashes, even on Windows. # Don't forget to use absolute paths, not relative paths. '/home/aortiz/sigcse/templates', )
-
Create a
base.html
file and place it in thetemplates
folder. The contents of this file should be:<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { background: #FFFFFF; color: #000080; font-family: sans-serif; font-size: medium; margin: 20px; } hr { border: 0; color: #B0C4DE; background-color: #B0C4DE; height: 1px; } table { border-collapse: collapse; border: 1px solid #000000; padding: 0px; margin-bottom: 10px; color: #000000; background: #E6E6FA; } td { border: 1px solid #000000; padding: 10px; text-align: center; } th { border: 1px solid #000000; padding: 10px; color: #008080; background: #B0E0E6; } .footer { font-size: 70%; color: #B0C4DE; text-align: center; } </style> <title> {% block title %}No Title{% endblock %} </title> </head> <body> {% block main %} {% endblock %} <hr/> <p class="footer"> Workshop: <em>Web Development with Python and Django</em> <br/> <strong>SIGCSE 2009</strong> </p> </body> </html>

Create a new application called
hello
. At the command line, type:python manage.py startapp hello
-
Create a
hello.html
file in thetemplates
folder. The contents of this file should be:{% extends "base.html" %} {% block title %}Hello{% endblock %} {% block main %} <h1>Hello {{ name }}!</h1> <p> Yes! This is my first Django Web page. </p> {% endblock %}
-
Create a view that sends information to the template. Edit the file
sigcse/hello/views.py
so that it has the following content:from django.shortcuts import render_to_response def say(request, name): return render_to_response('hello.html', {'name': name})
-
Link the view function with a URL pattern. Edit the
sigcse/urls.py
file by adding the highlighted line:urlpatterns = patterns('', # Example: # (r'^sigcse/', include('sigcse.foo.urls')), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: # (r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: # (r'^admin/(.*)', admin.site.root), (r'^hello/(w+)/$', 'sigcse.hello.views.say'), )

Using your web browser, visit the following URL:
http://localhost:8000/hello/World/
