[python]pyramid 学习6 (template)

直接调用模板

from pyramid.renderers import render_to_response

def sample_view(request):
    return render_to_response('templates/foo.pt',
                              {'foo':1, 'bar':2},
                              request=request)

Response输出

from pyramid.renderers import render
from pyramid.response import Response

def sample_view(request):
    result = render('mypackage:templates/foo.pt',
                    {'foo':1, 'bar':2},
                    request=request)
    response = Response(result)
    return response

view_config中定义模板

from pyramid.view import view_config

@view_config(renderer='templates/foo.pt')
def my_view(request):
    return {'foo':1, 'bar':2}

ZPT宏的运用(chameleon)

from pyramid.renderers import get_renderer
from pyramid.view import view_config

@view_config(renderer='templates/mytemplate.pt')
def my_view(request):
    main = get_renderer('templates/master.pt').implementation()
    return {'main':main}

templates/master.pt

<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:tal="http://xml.zope.org/namespaces/tal"
       xmlns:metal="http://xml.zope.org/namespaces/metal">
   <span metal:define-macro="hello">
     <h1>
       Hello <span metal:define-slot="name">Fred</span>!
     </h1>
   </span>
</html>

templates/mytemplate.pt

<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:tal="http://xml.zope.org/namespaces/tal"
       xmlns:metal="http://xml.zope.org/namespaces/metal">
   <span metal:use-macro="main.macros['hello']">
     <span metal:fill-slot="name">Chris</span>
   </span>
</html>

使用Chameleon的txt模板

from pyramid.view import view_config

@view_config(renderer='templates/mytemplate.txt')
def my_view(request):
    return {'name':'world'}

templates/mytemplate.txt

Hello, ${name}!

模板错误调试
命令行设置

PYRAMID_DEBUG_TEMPLATES=1 bin/paster serve myproject.ini

ini文件中定义

pyramid.debug_templates = true

设置mako模板目录

mako.directories = mypackage:templates

使用Mako模板

from pyramid.view import view_config

@view_config(renderer='foo.mak')
def my_view(request):
    return {'project':'my project'}

foo.mak

<html>
 <head>
     <title>${project} Application</title>
 </head>
   <body>
      <h1 class="title">Welcome to <code>${project}</code>, an
       application generated by the <a
       href="http://docs.pylonsproject.org/projects/pyramid/current/"
      >pyramid</a> web application framework.</h1>
   </body>
 </html>

Mako Template

from mako.template import Template
from pyramid.response import Response

def make_view(request):
    template = Template(filename='/templates/template.mak')
    result = template.render(name=request.params['name'])
    response = Response(result)
    return response

自动加载模板(如果模板有修改不用重启应用)
命令行

PYRAMID_RELOAD_TEMPLATES=1 bin/paster serve myproject.ini

.ini配置文件

[app:main]
pyramid.reload_templates = true
