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
