Pylons/Routes Did url_for() change within templates?

Question

I'm getting an error:

GenerationException: url_for could not generate URL. Called with args: () {}

from this line of a mako template:

<p>Your url is ${h.url_for()}</p>

Over in my helpers.py, I do have:

from routes import url_for

Looking at the Routes-1.12.1-py2.6.egg/routes/util.py, I seem to go wrong about line it calls _screenargs().

This is simple functionality from the Pylons book. What silly thing am I doing wrong? Was there a new url_current()? Where?

Answer 1

I didn't know url_for() (no arguments) was ever legal, but if it was and this is what you're referring to as "url_current", I believe the new approach is to use the url object, calling a method on it as url.current().
