五：创建model并同步数据库
现在我们打开blog目录下的models.py文件，这是我们定义blog数据结构的地方。
from django.db import models
# Create your models here.
class BlogsPost(models.Model):
title = models.CharField(max_length = 150)
body = models.TextField()
timestamp = models.DateTimeField()同步数据库却报错如下：
.......
.......
django.db.utils.OperationalError: near "��N": syntax error
解决不了之后在另一台机器上重复上述步骤成功
同步数据库
[root@localhost mysite16_2]# python manage.py syncdb
Creating tables ...
Creating table django_admin_log
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_groups
Creating table auth_user_user_permissions
Creating table auth_user
Creating table django_content_type
Creating table django_session
You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'root'): root
Email address: [email protected]
Password:
Password (again):
Superuser created successfully.

[root@localhost mysite16_2]# 六 ：设置admin应用
vi settings.py
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'blog',
)vi urls.py
[root@localhost mysite16_2]# more mysite16_2/urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'mysite16_2.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
)创建数据到后台
[root@localhost mysite16_2]# vi blog/models.py
from django.db import models
from django.contrib import admin
# Create your models here.
class BlogsPost(models.Model):
title = models.CharField(max_length = 150)
body = models.TextField()
timestamp = models.DateTimeField()
admin.site.register(BlogsPost)[root@localhost mysite16_2]# python manage.py syncdb

[root@localhost mysite16_2]# 启动服务登录admin
root 123456
python mange.py runserver
add一个博客
编辑让他显示正确的标题
[root@localhost mysite16_2]# vi blog/models.py
from django.db import models
from django.contrib import admin
# Create your models here.
class BlogsPost(models.Model):
title = models.CharField(max_length = 150)
body = models.TextField()
timestamp = models.DateTimeField()
class BlogPostAdmin(admin.ModelAdmin):
list_display = ('title','timestamp')
admin.site.register(BlogsPost,BlogPostAdmin)
七：创建blog的公共部分
从Django的角度看，一个页面具有三个典型的组件：一个模板（template）：模板负责把传递进来的信息显示出来。
一个视图（viw）：视图负责从数据库获取需要显示的信息。
一个URL模式：它负责把收到的请求和你的试图函数匹配，有时候也会向视
图传递一些参数。
7.1：创建模版页面让他在前台显示
查看表
[root@localhost mysite16_2]# sqlite3 db.sqlite3
SQLite version 3.6.20
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .tables
auth_group auth_user_user_permissions
auth_group_permissions blog_blogspost
auth_permission django_admin_log
auth_user django_content_type
auth_user_groups django_session
sqlite> select * from blog_blogspost;
1|wenchao first blog|this is my first blog|2014-11-07 11:32:34
2|second blog|this is my second blog|2014-11-07 11:36:01
sqlite> 常见模版目录及模版文件
[root@localhost blog]# cd templates/
[root@localhost templates]# ll
total 4
-rw-r--r--. 1 root root 114 Nov 7 11:50 archive.html
[root@localhost templates]# more archive.html
{% for post in posts %}
{{ post.title }}
{{ post.timestamp }}
{{ post.body }}
{% endfor %}
[root@localhost templates]# pwd
/root/Desktop/data/download/django/mysite16_2/blog/templates
[root@localhost templates]# 注册模版文件
在settings.py中增加
TEMPLATE_DIRS = (
'/root/Desktop/data/download/django/mysite16_2/blog/templates'
,
)7.2：创建视图函数
[root@localhost mysite16_2]# cd ../blog/
[root@localhost blog]# more views.py
from django.shortcuts import render
from django.template import loader,Context
from django.http import HttpResponse
from blog.models import BlogsPost
# Create your views here.
def archive(request):
posts = BlogsPost.objects.all()
t = loader.get_template("archive.html")
c = Context({'posts':posts})
return HttpResponse(t.render(c))
[root@localhost blog]# pwd
/root/Desktop/data/download/django/mysite16_2/blog
[root@localhost blog]# posts = BlogPost.objects.all() ：获取数据库里面所拥有BlogPost对象
t = loader.get_template("archive.html")：加载模板
c = Context({'posts':posts})：模板的渲染的数据是有一个字典类的对象Conte
xt提供，这里的是一对键值对。
7.3：创建url模式
增加blog的url
[root@localhost mysite16_2]# more urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'mysite16_2.views.home', name='home'),
url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
)
[root@localhost mysite16_2]# pwd
/root/Desktop/data/download/django/mysite16_2/mysite16_2
[root@localhost mysite16_2]# 在blog应用中创建blog文件
[root@localhost blog]# more urls.py
from django.conf.urls import *
from blog.views import archive
urlpatterns = patterns('',
url(r'^$',archive),
)
[root@localhost blog]# pwd
/root/Desktop/data/download/django/mysite16_2/blog
[root@localhost blog]# 之所以在blog应用下面又创建urls.py文件，是为了降低耦合度。这样mysite/
urls.py文件针对的是每个项目的url。
八：启动服务看前台显示的效果
应该是python路径找不到的问题
我的解决方法如下
[root@localhost blog]# cd /usr/lib/python2.6/site-packages/
[root@localhost site-packages]# ll *pth
-rw-r--r--. 1 root root 30 Feb 23 2013 abrt.pth
-rw-r--r--. 1 root root 47 Nov 7 12:45 path.pth
[root@localhost site-packages]# more path.pth
/root/Desktop/data/download/django/mysite16_2/
[root@localhost site-packages]# echo $PYTHONPATH
[root@localhost site-packages]# python

[root@localhost site-packages]# pwd

九：样式修改
创建基础模版
[root@localhost templates]# more base.html
fuwenchao first blog
hehe
{% block content %}
{% endblock %}
[root@localhost templates]#
修改模版引用基础模版
[root@localhost templates]# more archive.html
{% extends "base.html" %}
{% block content %}
{% for post in posts %}
{{ post.title }}
{{ post.timestamp }}
{{ post.body }}
{% endfor %}
{% endblock %}
[root@localhost templates]# 测试：
