traversal error when calling template for grok.View

[David Bain-5]

I have a simple class in app.py

class Master(grok.View):
    """The master page template macro."""
    # register this view for all objects
    grok.context(Interface)


there is a master template in app_templates/master.pt

The following code gives a traversal error:

hey = Master
hey(None,None)._render_template()
*** TraversalError: (None, 'master.css')

This line of code, by the way, seems to answer your question from
earlier today - the way you get a template to render something for you
is to instantiate its View, just like (I think) you're doing here.

Does your template try to determine the URL to "master.css" anywhere?
Whenever, in a template, you say "get the URL of <this>", you have to
make sure that "<this>" can be "traversed" to find where it lives and,
perhaps in this case, what lives inside of it.

Take a look at:

and see whether it addresses your situation.
