白手起家搭建django app

$django-admin.py startproject web2
$cd web2/
$python manage.py startapp blog
$vim web2/settings.py 

注意settings.py以下两个部分,首先要配置数据库，其次要在INSTALLED_APP里添加刚才新建的app

DATABASES = { 
    'default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' o
        'NAME': 'dj_db01',                      # Or path to database file if using sqlite3.
        # The following settings are not used with sqlite3:
        'USER': 'root',
        'PASSWORD': '', 
        'HOST': 'localhost',                      # Empty for localhost through domain sockets 
        'PORT': '',                      # Set to empty string for default.
    }   
}

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    'django.contrib.admindocs',
)

接下来编辑models.py

$vim blog/models.py

from django.db import models

在mysql里新建对应的数据里

mysql> create database dj_db01 default charset utf8;

现在可以自动生成各种表啦

$ python manage.py syncdb

现在编辑以下url的config

$vim web1/urls.py

from django.conf.urls import patterns, include, url 

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'web1.views.home', name='home'),
    # url(r'^web1/', include('web1.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    # url(r'^admin/', include(admin.site.urls)),
    url(r'^blog/$','blog.views.index'),
)

$mkdir blog/static/images

然后从别的地方拷贝过来一张图，这里我拷贝过来的img2.jpg

接下来编辑一下页面

$mkdir blog/templates
$vim blog/templates/index.html

 <h1>hello world</h1>
 <img src='/static/images/img2.jpg'/>

运行一下

python manage.py runserver 3900
