def build_url(self, values, **args):
"""
build_url(values)
Build a URL for this resource.
The URL is built using the current WSGI environ, so this function
must be called from inside a request context. Furthermore, the
resource must have already been routed to in the current app
(see: :meth:`findig.dispatcher.Dispatcher.route`), and this method
must be passed values for any variables in the URL rule used to
route to the resource.
:param values: Values for the variables in a URL rule used to
route to the resource.
:type values: :class:`dict`
Example::
>>> from findig import App
>>> app = App()
>>> @app.route("/index/<int:num>")
... @app.resource
... def item(num):
... return {}
...
>>> with app.test_context(path="/index/1"):
... item.build_url(dict(num=4))
...
'/index/4'
This method is *not* abstract.
