Question

Starting using werkzeug, i try to map urls (from a file urls.py) to views (from a folder views and then in different files to manage differents kinds of view), my folder organisation looks like that :

myapp/
   application.py
   urls.py
   views/
      __init__.py
      common.py
      places.py
      ...

my urls.py files looks like that:

from werkzeug.routing import Map, Rule  

url_map = Map([  
Rule('/places', endpoint='places.overview')  
])  

and obviously i got that piece in the views/places.py file :

def overview(request):
    mycode...
    render_template('places.html', extra...)

Most of werkzeug examples show the utilisation of the decorator expose to attach urls to views. It’s practical for an app with 5 or 6 urls but can become a hell when you got more…

Is there a simple way to map the urls directly to the views???
Thanks.

Here is a simplified example:

import views

def app(environ, start_response):
    urls = url_map.bind_to_environ(environ)
    request = Request(environ)
    endpoint, params = urls.match()
    names = endpoint.split('.')
    view = views
    for name in names:
        if not hasattr(view, name):
            __import__(view.__name__, None, None, [name])
        view = getattr(view, name)
    try:
        response = view(request)
    except werkzeug.exceptions.HTTPException, exc:
        response = exc
    return response(environ, start_response)
