Third, Django installation

Since Django is a Python web framework, you must first install Python to run the Django program.

Django-supported Python versions:

Django Version	python version
1.8	2.7,3.2 (until the end of 2016), 3.3,3.4,3.5
1.9,1.10	2.7,3.4,3.5

Installation:

1) using the Python PIP installation module, if you want to install the Django1.8.1 version, command: Pip install django==1.8.1

Verify:

You can import the Django module test on the Python command line interface, and if the installation is successful, the following information is displayed:

>>> Import django>>> Print (Django.get_version ()) 1.8.1

Note: The following issues may occur when you enter django-admin at the command prompt after the Windows installation has completed Django

Iv. creating a simple Web site with Django

Django creates a site that is quick and easy and requires only a few simple commands, and a basic website is created.

1) Create MySite Project

c:\users\administrator>django-admin.py Startproject mysitec:\users\administrator>

After the command is complete, you can see a new MySite directory, the MySite directory tree as follows:

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M02/08/65/wKiom1ngpMrwOb4eAAAH3Akp0s0823.png "title=" Qq20171013193253.png "alt=" Wkiom1ngpmrwob4eaaah3akp0s0823.png "/>

File Description:

django-admin.py: is a Django command-line tool for managing tasks

Manage.py:Django Project Management command-line tools are automatically generated for each project you create.

manage.py is a simple package for django-admin.py, and it helps us do two things in addition:

1. 1. It puts your project's package in the Sys.path

   2. It sets the Django_settings_module environment variable to the location of your project's setting.py file.

Urls.py:python the processing mechanism of URL matching

settings.py: Site project configuration file, you can configure the site language, database connection, static content path and so on.

2) Use manage.py to create an application (app) for MySite, Mysite_app

650) this.width=650; "src=" Https://s5.51cto.com/wyfs02/M00/A7/1C/wKioL1ngo0iiuu5qAAAf1oK_wmw357.png "title=" Untitled. png "alt=" Wkiol1ngo0iiuu5qaaaf1ok_wmw357.png "/>

3) At this point, a simple site is created to complete, next test site can not access

To run the server:

From the output of the program you can see that the Web server has been created successfully, running on port 8000 of 127.0.0.1

Access Server (127.0.0.1:8000):
