It verifies that both apps are really running with the right code. But for some
reason, it seems to be messed up at the time that you run any controller in
your app. That's a puzzle to me.
I appreciate your patience...
So, here's something we can try. In your first (alphabetically) model, create a
dict:
urldebug = dict()
urldebug['model1name'] = URL.__name__
The idea will be to trace URL.__name__ as we progress through a request. So at
the beginning of each model file:
urldebug['model2name'] = URL.__name__
...and one more at the end of your last model.
Then one more in one of your failing controllers (that is, failing if you try
to call URL with one argument; not actually failing, because we want to get to
the view).
Then pass urldebug to your view, and dump it there. {{=BEAUTIFY(urldebug)}}
will do the trick.
Hopefully we'll see the name change from _URL to URL at some point in the
sequence, and then we can go lion hunting.
