Subject: view-callable class - request arg receives context object

Docs say you should expect to handle a request argument in a view-callable class.

http://pyramid.readthedocs.org/en/latest/narr/views.html#defining-a-v...

But I found I was getting a context object for the request arg.

Does this mean context and request are being passed (in that order) as positional args, rather can keywords?

I know I can just reverse the order so context is first - just asking if there is anything wrong with below code that would cause this, or this is view-callables are called this way for any reason?

class SomeView():
    """
    """
    def __init__(self,
                 request, # called positionally?
                 context, # ..
                 *args,
                 **kwargs
                 ):
        print('"request" is {0}'.format(request.__class__))
        print('"context" is {0}'.format(context.__class__))

"request" is <class 'pyramid.traversal.DefaultRootFactory'>
"context" is <class 'pyramid.util.Request'>

They are called positionally via introspection and not by name. The
calling convention is here:

Thanks Michael

Is the example below given
in #defining-a-view-callable-as-a-class incorrect?

I.e. ``request`` is a context-object because it is the first-position arg.

from pyramid.response import Response

class MyView(object):
    def __init__(self, request):
        self.request = request

    def __call__(self):
        return Response('hello')

No, it's correct. As I said it uses introspection to see what args are
there. If your function takes 1 arg, it will be the request. If it
takes 2 or more args the first two will be context and request in that
order. You need to be aware of this if you try to do (request, *args)
because the first arg will be context and args[0] will be request.
