时候不早了�Q�废话也不多说了。开始吧�Q?br />1. paster create --template=pylons minispider
2. MySQL�Q�徏立数据库minispider

CREATE TABLE minispider.titleinfo
( id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
  link VARCHAR ( 255 ) NOT NULL DEFAULT '' ,
  description VARCHAR ( 255 ) NOT NULL DEFAULT '' ,
  sitename VARCHAR ( 255 ) NOT NULL DEFAULT '' ,
  updatetime TIMESTAMP NOT NULL DEFAULT 0 ,
   PRIMARY KEY (id)
)

3. The Model
1) 修改development.ini�Q�代码如下：

1#
2# minispider - Pylons development environment configuration
3#
4# The %(here)s variable will be replaced with the parent directory of this file
5#
6[DEFAULT]
7debug = true
8email_to = you@yourdomain.com
9smtp_server = localhost
10error_email_from = paste@localhost
11
12[server:main]
13use = egg:Paste#http
14host = 0.0.0.0
15port = 5000
16
17[app:main]
18use = egg:minispider
19cache_dir = %(here)s/data
20session_key = minispider
21session_secret = somesecret
22
23# If you'd like to fine-tune the individual locations of the cache data dirs
24# for Myghty, the Cache data, or the Session saves, un-comment the desired
25# settings here:
26#myghty_data_dir = %(here)s/data/templates
27#cache_data_dir = %(here)s/data/cache
28#session_data_dir = %(here)s/data/sessions
29
30# Specify the database for SQLObject to use via pylons.database.PackageHub.
31# %(here) may include a ':' character on Windows environments; this can
32# invalidate the URI when specifying a SQLite db via path name. Refer to the
33# SQLObject documentation for a special syntax to preserve the URI.
34#sqlobject.dburi = sqlite:%(here)s/somedb.db
35sqlobject.dburi = mysql://root:123456@localhost:3306/minispider
36
37# WARNING: *THE LINE BELOW MUST BE UNCOMMENTED ON A PRODUCTION ENVIRONMENT*
38# Debug mode will enable the interactive debugging tool, allowing ANYONE to
39# execute malicious code after an exception is raised.
40#set debug = false

�W?5行�ؓ��d��的部分�?br />2�Q�在models目录下，建立msmodel.py�Q�代码如下：

from sqlobject import *
from pylons.database import PackageHub
hub = PackageHub("minispider")
__connection__ = hub

class titleinfo(SQLObject):
    link = StringCol(length=255)
    description = StringCol(length=255)
    sitename = StringCol(length=255)
    updatetime = DateTimeCol()

修改__init__.py�Q�代码如下：

## NOTE
## If you plan on using SQLObject, the following should be un-commented and provides
## a starting point for setting up your schema

#from sqlobject import *
#from pylons.database import PackageHub
#hub = PackageHub("minispider")
#__connection__ = hub

# You should then import your SQLObject classes
# from myclass import MyDataClass
from msmodel import titleinfo

4.The view
在templates文�g夹下建立ms文�g夹，在ms文�g中徏立list.myt�Q�代码如下：

<html>
<head>
<title>Generated by Mini Spider v0.1title>
head>
<body>
<table width="80%"  border="0">
  <tr>
    <td width="60%"><strong>Whatstrong>td>
    <td width="20%"><strong>Wherestrong>td>
    <td width="20%"><strong>Whenstrong>td>
  tr>
% for ti in c.titleinfo:
  <tr>
    <td><a href="<% ti.link %>" target="_blank"><% ti.description %>a>td>
    <td><% ti.sitename %>td>
    <td><% ti.updatetime %>td>
  tr>
% #endfor
table>
body>
html>

务必注意代码的羃�q�！��费了偶半个多小�Ӟ��

5.The controller
命��o行运行：
cd minispider
paster controller ms
��controllers文�g夹下ms.py修改�Q�代码如下：

from minispider.lib.base import *

class MsController(BaseController):

  template_prefix = '/ms'

  def index(self):
    redirect_to(action='list')

  def list(self):
    c.titleinfo = list(model.titleinfo.select())
    return render_response(self.template_prefix + '/list.myt')

6. run
命��o行运行：
paster serve --reload development.ini
ok�Q�访问：http://127.0.0.1:5000/ms
�l�果�c�M��Q?br />
