django 学习笔记（一）搭建基础环境

1、安装django 下载地址 https://github.com/django/django

　　解压后进入文件夹运行指令 >> python setup.py install

2、创建工程

     >> django-admin.py startproject web_1

3、修改默认配置

　　cd web_1

　　修改 settings.py

LANGUAGE_CODE = 'zh-Hans'

TIME_ZONE = 'Asia/Shanghai'

4、添加app

　　修改 settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog',
] 

添加blog应用

5、添加blog应用对应的url

　　修改 urls.py

from django.conf.urls import url
from django.contrib import admin
# 引入模块
from blog import views as blog_views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # 添加url映射
    url(r'^blog/index/$',blog_views.index),
]    

　　创建blog应用

　　返回工程根目录

　　执行命令 >> django-admin.py startapp blog

6、添加view.index 解析

　 blog/views.py：

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render

from django.http import HttpResponse

# Create your views here.

def index(req):
    return HttpResponse("<h1>hello world!</h1>")

7、运行服务

　　>> python manage.py runserver

　　如果出现如下错误：

Performing system checks...

System check identified no issues (0 silenced).

You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

　　先运行指令: >> python manage.py migrate

　　重新启动服务：>> python manage.py runserver

　　出现如下内容，恭喜你，服务启动成功了
