[FE-discuss] OneOf with deferred call on function?

[Iain Duncan]

Hi folks, I'm wanting to do the following

validator = OneOf( [ <list generated at call time> ] )

I was hoping this would work

validator = OneOf( get_valid_options )

but it doesn't. Is there something I'm missing to do the above?

Thanks
Iain

Well... doesn't work. You could, I suppose, do:

class OneOfMine(OneOf):
get_valid_options = None
@property
def list(self):
return self.get_valid_options()
