Twisted Adapters for Templating Engines
Project description
txTemplate provides adapters for a few popular template engines to make them easily callable and usable within Twisted Web.
txTemplate uses zope.interface to provide a consistent loader and template interface for every template engine.
Supported Template Engines
ClearSilver
Genshi
Jinja2
Getting Started
- All you really need to do to use txTemplate in twisted is:
import it
create a loader pointed at your template directory
load a template with said loader
call template.render, attach callbacks to the rendered deferred (if desired) and return the deferred from and of your twisted.web.resource.Resource render_* methods.
Here’s a code sample of a Twisted Web resource that uses txTemplate to render a lovely Genshi template to say Hello World in HTML:
import os from twisted.application import internet from twisted.internet import reactor from twisted.web import resource from twisted.web import server import txtemplate TEMPLATE_DIR = os.path.join(os.path.dirname(os.path.abspath(__file__)), "templates") class HelloWorld(resource.Resource): def __init__(self): resource.Resource.__init__(self) self.loader = txtemplate.GenshiTemplateLoader(TEMPLATE_DIR) def getChild(self, name, request): return self def render_GET(self, request): template_name = "hello.xhtml" template = self.loader.load(template_name) context = {"greeting": "Hello", "greetee": "World"} def cb(content): request.write(content) request.setResponseCode(200) request.finish() d = template.render(**context) d.addCallback(cb) return server.NOT_DONE_YET site = server.Site(HelloWorld()) reactor.listenTCP(8888, site) reactor.run()
This example is included in txtemplate/examples/txweb.py and the root.xhtml template is in txtemplate/examples/templates/root.xhtml.
