This document introduces Django, a Python web framework. It discusses what a web framework is and compares building a Python web application without a framework versus using Django's MVC design pattern. It provides instructions for getting started with Django on Windows, including installing Python, adding it to the environment path, installing Django via pip or Git, and selecting an IDE like Eclipse with the PyDev plugin. The document concludes with an overview of a basic Django project directory structure and running a "Hello World" application on the development server.

1. Introduction to Django
The Django Book online(ch.1-2)

2. What Is a Web Framework?

5. Python web application without FrameWork
• fulfill the requirements of CGI
• connects to a database
• one-off page
• Example

6. The MVC Design Pattern(Django)
• models.py (the database tables)
• views.py (the business logic)
• urls.py (the URL configuration)
• latest_books.html (the template)
• Example

7. Getting Start(for windows)
• Django is “just” Python code, it runs anywhere Python does
• So, the next step is to install Python:
• https://www.python.org/download/
• then add the Python to the environment variable
• 開始->電腦右鍵->進階系統設定->進階->環境變數->在path後面加
入;D:Python27
• 之後就可以在cmd使用python囉

8. Install Django
• 2種方法 擇一即可:
• 1.pip(Python 套件管理工具)
• (1)到https://pip.pypa.io/en/latest/installing.html#install-pip下載get,
• (2)增加環境變數;D:Python27Scripts
• (3-1) pip install Django==1.6.5
• (3-2) pip install https://www.djangoproject.com/download/1.7c1/tarball/
• 2.Git (development version)
• git clone https://github.com/django/django.git

9. OK , 現在來選擇開發工具吧

10. 各種IDE
• Komodo Edit
• IDLE
• wxGlade
• Notepadd++
• Ipython
• Eclipse

11. 這邊介紹Eclipse

12. 既然選擇 Eclipse,就不能不裝
plugin
• 在Eclipse內安裝PyDev pligin
• Help->SoftWare Updates -> Available Software - > 按Add Site
• http://update-production-pydev.s3.amazonaws.com/pydev/updates/site.xml

13. 終於可以Hello World了
• Eclipse ->run server
• 打開broweser 127.0.0.1/8000
It works!
• Admin page

14. 專案目錄
• mysite/
• manage.py -- shell that that you interact with your project
• mysite/ -- main package with setting
• __init__.py -- A file required for Python to treat the mysite directory as a
package (i.e., a group of Python modules)
• settings.py -- configuration of the project ( here import the package
we created)
• urls.py -- url routing work
• wsgi.py -- An entry-point for WSGI-compatible webservers to serve
your project

15. Thank you
