I wonder if I could get some clarification on the usage of
as a prefix to method names in CFWheels. It seems to me that this is used in lieu of actually making a method private. The only reference I have been able to find for this in the docs is a mention in passing:
If you have functions that should only be called from the plugin itself, we recommend starting the function name with the
character (this is how many internal Wheels functions are named as well)
(my emphasis, and that is from I could find no other explicit explanation, but
is hard to google for, so this means nothing. I didn't find anything further searching for "private" or "internal" either, that said. I want code to run every time a model object is created. Normally I would put this in the constructor of the class, but for reasons that I cannot fathom, CFWheels does not call
when it creates an object. So that's no good. I have found
, and if I override that in my own models, it seems to work as I'd expect. Certainly when I call
on the model factory object, it seems to be called on the returned model object(s). However I am cautious that it's a method prefixed with
, therefore "internal" to CFWheels. I should probably not be messing with it, or calling it directly (even in an overridden implementation of itself). So is there a more CFWheels-idiomatic way of doing this? Or am I fine with this approach? Cheers.

@Adam Cameron could you not use the
Callback Function.

Oooh, I'll look at that tomorrow (in the pub watching sportsball ATM). Thanks dude.
Yep that did the trick! Thanks @Peter Amiri 🙂
