A Web site in the Django Framework can contain multiple Django projects, while a Django project contains a specific set of objects, including the design of the URL, the design of the database, and other options.
django-admin.py-----It has a number of command options that you can use to manipulate the project. With the startproject command option, you can generate a directory of project names that includes the file structure needed for a basic Web application:
__init__.py: Empty file, used primarily to tell Python to use this site directory as a python package
manage.py: Allows site administrators to manage Django projects
Configuration file for Settings.py:django project
urls.py: Write a configuration file that includes a URL, which is how users access the Django app
Attention:
(1) The Django project is handled as a Python package, so when the project is named, try not to conflict with the name in the existing Python module.
1. Create a new project and an app
Attention:
(1) When performing python3.4 manage.py startapp firstapp: Importerror:no module named ' MySQLdb '
The Python standard library does not have an integrated MySQL interface program, and MySQLdb is a third-party package that needs to be downloaded and installed separately. Currently MYSQLDB does not support python3.x, can install Pymysql instead of Mysql-python.
# yum-y Install mysql-python.x86_64 # #安装后, you must recompile python, but use the default python.
For Connector/python 2.0, the source tree had been reorganized to having a single code base, for easier maintenance, testing , and distribution.
# tar XVF mysql-connector-python-2.0.4.tar.gz
# python3.4 setup.py Install--help
# python3.4 setup.py Install
Copying build/lib/mysql/connector/catch23.py-/usr/local/python3.4.3/lib/python3.4/site-packages/mysql/ Connector
(2) manage.py when creating an app, it reads the settings.py configuration
(3) Pymysql.err.InternalError: (1130, "Host":: 1 ' isn't allowed to connect to this MySQL server ")

2. A lightweight Web application server in the Django framework
The Django built-in server can be loaded automatically when the code is modified, enabling rapid website development.
# python3.4 manage.py runserver 0.0.0.0:8000 & # #使用http://192.168.0.4:8000/Visit Web page
