| 安装：1. 下载安装工具ez_setup.py2. 命令行运行：python ez_setup.py Pylons 耐心等待，安装结束。3. 设置环境变量 系统变量->path->;C:\Python24\Scripts4. 命令行运行：paster 产生下面类似结果，则说明安装成功。运行结果Usage: C:\Python24\Scripts\paster-script.py COMMANDusage: paster-script.py [paster_options] COMMAND [command_options]

pylons: controller Create a Controller and functional test for it
The Controller command will create the standard controller template file and associated functional test to speed creation of controllers.
Example usage::
yourproj% paster controller comments Creating yourproj/yourproj/controllers/comments.py Creating yourproj/yourproj/tests/functional/test_comments.py
If you'd like to have controllers underneath a directory, just include the path as the controller name and the necessary directories will be created for you::
yourproj% paster controller admin/trackback Creating yourproj/controllers/admin Creating yourproj/yourproj/controllers/admin/trackback.py Creating yourproj/yourproj/tests/functional/test_admin_trackback.py
shell Open an interactive shell with the Pylons app loaded
The optional CONFIG_FILE argument specifies the config file to use for the interactive shell. CONFIG_FILE defaults to 'development.ini'.
This allows you to test your mapper, models, and simulate web requests using ``paste.fixture``.
Example::
$ paster shell my-development.ini 开始动手：1. 建立一个Pylons工程 命令行运行： F:\python\lab\Pylons>paster create --template=pylons helloworld 产生下面类似结果：运行结果Selected and implied templates: pylons#pylons Pylons application template

3. 禁用调试功能 将development.ini文件中的： #set debug = false 改成： set debug = false
4. 创建一个控制器、修改Routes 1. 命令行运行：F:\python\lab\Pylons\helloworld>paster controller hello 2. 修改helloworld/controllers/hello.py，代码如下：
1from helloworld.lib.base import *23class HelloController(BaseController):4 def index(self):5 return Response('hello world')
3. 修改helloworld/config/routing.py，代码如下：
1""" 2Setup your Routes options here 3""" 4import sys, os 5from routes import Mapper 6 7def make_map(global_conf={}, app_conf={}): 8 root_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) 910 map = Mapper(directory=os.path.join(root_path, 'controllers'))11 12 # This route handles displaying the error page and graphics used in the 404/50013 # error pages. It should likely stay at the top to ensure that the error page is14 # displayed properly.15 map.connect('error/:action/:id', controller='error')16 17 # Define your routes. The more specific and detailed routes should be defined first,18 # so they may take precedent over the more generic routes. For more information, refer19 # to the routes manual @ http://routes.groovie.org/docs/20 map.connect('', controller='hello', action='index')21 map.connect(':controller/:action/:id')22 map.connect('*url', controller='template', action='view')2324 return map 4. 删除public/index.html。访问http://127.0.0.1:5000/hello和http://127.0.0.1:5000/，你将看到“hello world”。
5.模版和请求周期 1.创建模版文件：helloworld/templates/serverinfo.myt，代码如下：<p>Hi, here's the server environment: <br /><% str(request.environ) %></p>
<p>and here's the URL you called: <% h.url_for() %></p> 2. 修改helloworld/controllers/hello.py，代码如下：from helloworld.lib.base import *
class HelloController(BaseController): def index(self): return Response('hello world') def serverinfo(self): return render_response('/serverinfo.myt') 3.访问http://127.0.0.1:5000/hello/serverinfo，你将看到下面类似结果：运行结果Hi, here's the server environment:{'HTTP_REFERER': 'http://pylonshq.com/docs/0.9.3/getting_started.html', 'paste.recursive.forward': , 'pylons.routes_dict': {'action': 'serverinfo', 'controller': 'hello', 'id': None}, 'paste.recursive.include': , 'SCRIPT_NAME': '', 'REQUEST_METHOD': 'GET', 'PATH_INFO': '/hello/serverinfo', 'SERVER_PROTOCOL': 'HTTP/1.1', 'QUERY_STRING': '', 'paste.throw_errors': True, 'CONTENT_LENGTH': '', 'HTTP_ACCEPT_CHARSET': 'gb2312,utf-8;q=0.7,*;q=0.7', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.8.1) Gecko/20061010 Firefox/2.0', 'HTTP_CONNECTION': 'keep-alive', 'HTTP_COOKIE': 'helloworld=ef423552a79452b4061d63335840e6690237c4375498846bc40a5e9218518af5', 'SERVER_NAME': '0.0.0.0', 'REMOTE_ADDR': '127.0.0.1', 'pylons.environ_config': {'cache': 'beaker.cache', 'session': 'beaker.session'}, 'paste.expected_exceptions': [], 'wsgi.url_scheme': 'http', 'beaker.cache': , 'paste.config': {'global_conf': {'error_email_from': 'paste@localhost', 'email_to': 'you@yourdomain.com', 'debug': 'false', '__file__': 'F:\\python\\lab\\Pylons\\helloworld\\development.ini', 'smtp_server': 'localhost', 'here': 'F:\\python\\lab\\Pylons\\helloworld'}, 'app_conf': {'session_key': 'helloworld', 'package': 'helloworld', 'session_secret': 'somesecret', 'cache_dir': 'F:\\python\\lab\\Pylons\\helloworld/data', 'session_data_dir': 'F:\\python\\lab\\Pylons\\helloworld/data\\sessions', 'cache_data_dir': 'F:\\python\\lab\\Pylons\\helloworld/data\\cache'}}, 'SERVER_PORT': '5000', 'paste.recursive.script_name': '', 'wsgi.input': , 'HTTP_HOST': '127.0.0.1:5000', 'beaker.session': {'_accessed_time': 1164775636.45, '_creation_time': 1164775537.0710001}, 'paste.recursive.include_app_iter': , 'wsgi.multithread': True, 'paste.httpexceptions': , 'HTTP_ACCEPT': 'text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5', 'wsgi.version': (1, 0), 'paste.registry': , 'wsgi.run_once': False, 'wsgi.errors': ', mode 'w' at 0x00ACE0B0>, 'wsgi.multiprocess': False, 'HTTP_ACCEPT_LANGUAGE': 'zh-cn,zh;q=0.5', 'CONTENT_TYPE': '', 'REMOTE_HOST': 'localhost', 'HTTP_ACCEPT_ENCODING': 'gzip,deflate', 'HTTP_KEEP_ALIVE': '300'}
and here's the URL you called: /hello/serverinfo 6. 使用Sessions 代码片段：1def serverinfo(self):2 session['name'] = 'George'3 session.save()4 return render_response('/serverinfo.myt')7. 控制器变量和模版全局变量 控制器变量 1. 修改helloworld/controllers/hello.py，代码如下：from helloworld.lib.base import *
class HelloController(BaseController): def index(self): return Response('hello world') def serverinfo(self): c.value = 2 return render_response('/serverinfo.myt') 2. 修改helloworld/templates/serverinfo.myt，代码如下：<p>The value of <tt>c.value</tt> is:<% c.value %>
3. 访问http://127.0.0.1:5000/hello/serverinfo，你将看到“The value of c.value is: 2”。 模版全局变量 1.修改lib/app_globals.py，代码如下： 1class Globals(object): 2 3 def __init__(self, defaults, app, **extra): 4 self.message = 'Hello' 5 6 def __del__(self): 7 """ 8 Put any cleanup code to be run when the application finally exits 9 here.10 """11 pass 2.修改helloworld/controllers/hello.py，代码如下：
from helloworld.lib.base import *
class HelloController(BaseController): def index(self): return Response('hello world') def serverinfo(self): c.value = 2 return render_response('/serverinfo.myt') def app_globals_test(self): resp = Response() if g.message == 'Hello': resp.write(g.message) g.message = 'Hello World!' else: resp.write(g.message) return resp 3.访问http://127.0.0.1:5000/hello/app_globals_test/，你将看到“Hello World!”参考资料：http://pylonshq.com/docs/0.9.3/getting_started.html |
