That shouldn't be an issue, you can access the currently dispatched controller using tg.dispatched_controller() This way you will be able to access the controller instance and retrieve the property you need even from the class method.
About the behavior of the before_validate parameters, that is actually the right one. I used *args and **kw just because I'm lazy and didn't want to specify the right parameters. The expected before_validate hook signature is: def before_validate_hook(remainder, params): if you use *args and **kw you simply get the remainder and the params inside the args argument :D On Wed, Apr 18, 2012 at 10:02 AM, Moritz Schlarb <[email protected]> wrote: > I wanted to do it that way, but since I need a property of the class that I > want to "inject" into kw, I can't do it as a classmethod.... > But it doesn't really matter if it gets injected twenty times... > > Thanks anyway! > > Am Dienstag, 17.
