Working With Rails

I tried posting this on Railsforums.com, but got no answer after a week. I’m guessing that the answer is easy, I just don’t know where to look for it. Anyway, here it is:

1. def self.subclasses(direct = false)
2. classes = []
3. if direct
4. ObjectSpace.each_object(self.class) do |c|
5. next unless c.superclass == self
6. classes << c
7. end
8. else
9. ObjectSpace.each_object(self.class) do |c|
10. next unless c.ancestors.include?(self) and (c != self)
11. classes << c
12. end
13. end
14. classes
15. end
    [/code]

The problem comes from when I call this function within the view that displays the select box. What is happening is that ObjectSpace only sees the current object associated with this view (a subclass of Field), and the Field parent, probably because Rails’ dynamic loading doesn’t see fit to load the other models within the hierarchy (which is understandable default behavior). I could manually add requires to see all the objects in question, but then I would have to update that list of requires every time a change is made to the hierarchy, and depending on where I stick the requires in the first place, I may be loading code that won’t be used in a particular situation. Since this seems like an obvious issue to come up, I’m imagining that Rails has solved this in some beautiful way, but I haven’t been able to find what it is.

I have a temporary solution in place-I stuck the name of every class in the two views that needed their names-but then if a class is added to the hierarchy, it will have to also be added to both of those places, which is not acceptable, for obvious reasons.

So that’s the story. Can anyone help me out?
