I am having a problem using the view_config decorator.
We have extended the view_config decorator to automatically include
the match_param
attribute. This new decorator is called action_config. I have
already eliminated
this as the source of my troubles, as the stock view_config decorator raises
the same errors.
I have 2 routes, 'contact' and 'contact id' that are being used by 4
view callables on a ContactHandler class. Only 1 of the view callables is using
the 'contact id' route while the other 3 use the 'contact' route.
(Note: Our project is using namespace packages, so application.lib is
located at application.lib/application/lib on disk, for example)
Routes
application/module/__init__.py:
...
config.add_route('contact',
'/contact/{action}',
factory='application.lib.contexts:ContactFactory')
config.add_route('contact id',
'/contact/{action}/{contact_id}',
factory='application.lib.contexts:ContactFactory')
config.scan('application.lib.handlers')
...
Callables
application.lib/application/lib/handlers/contact.py:
class ContactHandler(Handler):
@action_config(route_name='contact id')
def edit(self):
""" Add or edit a contact """
...
@action_config(route_name='contact')
def index(self):
""" Return list of contacts. """
...
@action_config(route_name='contact')
def search(self):
""" Return a list of contacts matching search parameters """
...
@action_config(route_name='contact')
def find(self):
""" Find a contacts """
...
I can't figure out how or why these route is conflicting. My application is
only scanning application.lib/application/lib/handlers/contact.py in one place
and each view/callable method is only decorated once, each for a specific route
as defined in my __init__.py.
If I decorate the ContactHandler class with @view_defaults(route_name='contact')
and remove all of the @action_config decorators from my class methods, no errors
are raised. However, this is not ideal as I one route requires an ID parameter
and one does not.
When using pdb.set_trace() inside of the our extended action_config
__call__ method
inside of the callback passed to view_config.venusian.attach(),
I find that the callback is being called 3 times for each of these routes.
I don't know if that is related to the problem.
Stragely, I am using this same action_config decorator in another module
inside of my application with no problems.
The error:
