Templates¶

nanohttp have no any plan to officially support template engines. But you can implement any template engines (like Mako, Jinja, Mustache, etc.).

This is how to use Mako template engine with the nanohttp:

main.py

import functools
from os.path import dirname, abspath, join

from mako.lookup import TemplateLookup

from nanohttp import Controller, context, Static, settings, action


here = abspath(dirname(__file__))
lookup = TemplateLookup(directories=[join(here, 'templates')])


def render_template(func, template_name):

    @functools.wraps(func)
    def wrapper(*args, **kwargs):

        result = func(*args, **kwargs)
        if hasattr(result, 'to_dict'):
            result = result.to_dict()
        elif not isinstance(result, dict):
            raise ValueError('The result must be an instance of dict, not: %s' % type(result))

        template_ = lookup.get_template(template_name)
        return template_.render(**result)

    return wrapper


template = functools.partial(action, content_type='text/html', inner_decorator=render_template)


class Root(Controller):
    static = Static(here)

    @template('index.mak')
    def index(self):
        return dict(
            settings=settings,
            environ=context.environ
        )
