You can't manipulate scopes that way.

def d(msg='my default message', alt="none"):
    def decorator(func):
        def newfn(request, **kwargs):
            if msg and alt:
               kwargs['variable'] = "Read Only"
            return func(request, **kwargs)
        return newfn
    return decorator

@d('hai', 'begin')
def company(request, variable):
   print(variable) #available as an argument to this view
   return ...
