Here's a simple Tool for Mako templating:
import cherrypy from mako.lookup import TemplateLookup class MakoHandler(cherrypy.dispatch.LateParamPageHandler): """Callable which sets response.body.""" def __init__(self, template, next_handler): self.template = template self.next_handler = next_handler def __call__(self): env = globals().copy() env.update(self.next_handler()) return self.template.render(**env) class MakoLoader(object): def __init__(self): self.lookups = {} def __call__(self, filename, directories, module_directory=None, collection_size=-1): # Find the appropriate template lookup. key = (tuple(directories), module_directory) try: lookup = self.lookups[key] except KeyError: lookup = TemplateLookup(directories=directories, module_directory=module_directory, collection_size=collection_size, ) self.lookups[key] = lookup cherrypy.request.lookup = lookup # Replace the current handler. cherrypy.request.template = t = lookup.get_template(filename) cherrypy.request.handler = MakoHandler(t, cherrypy.request.handler) main = MakoLoader() cherrypy.tools.mako = cherrypy.Tool('on_start_resource', main)
Use it like this:
@cherrypy.expose @cherrypy.tools.mako(filename="index.html") def index(name=None): return {'username': name}
You will also need two config options:
tools.mako.collection_size = 500 tools.mako.directories = "path/to/templates"
index.html:
<html>
<body>
Hello, ${username}!
</body>
</html>
To avoid UTF-8 encoding problems use following for template lookup
lookup = TemplateLookup(directories=directories, module_directory=module_directory, collection_size=collection_size,output_encoding='utf-8', encoding_errors='replace')
