Yeah, I know. The "novar" default was left over from passing strings
to the page via querystring. Like I said I'm just throwing stuff at
the framework right now to kind of "feel it out" and get a grip on how
it handles stuff.
Just to rule out the possibility that I did somthing wierd I created a
new project, added a new controller (changed nothing, its index action
returns 'Hello World', and just add the line to by BaseController to
print out the class name and received almost the same result:
CtestController
TemplateController
ErrorController
TemplateController
ErrorController
TemplateController
ErrorController
TemplateController
ErrorController
> Does it make a difference if you omit the trailing slash?
Nope.
> You mean the error controller itself is failing to return a page?
Here's my new test BaseController on the old project:
fp = open('dump.txt', 'w')
class BaseController(WSGIController):
def __call__(self, environ, start_response):
"""Invoke the Controller"""
# WSGIController.__call__ dispatches to the Controller method
# the request is routed to. This routing information is
# available in environ['pylons.routes_dict']
fp.write(self.__class__.__name__ + ':\n\n')
try:
result = WSGIController.__call__(self, environ,
start_response)
fp.write('\n'.join(result) + '\n\n')
return result
finally:
Session.remove()
And here's the output file (sorry about the length):
