What does the Magic Field Name position do?
I was looking here:
http://wiki.rubyonrails.com/rails/pages/MagicFieldNames
And unfortunately that documentation is incomplete.
Thanks.

When using acts_as_list, it keeps track of the position of the item on
the list.

Can the list be specific to a belongs_to relationship?

Yes - use :order => :position in the belongs_to.
D’oh… Must not post before tea…
class Parent < AR::Base
has_many :children, :order => :position
endclass Child < AR::Base
acts_as_list, :scope => :parent
belongs_to :parent, :order => :position
end
Ahhh, that is cool.
One more question: what is the difference between specifying the :order
in belongs_to vs. has_many? I would think you only need specify :order
in the has_many declaration. ??

Just looking at it, I can’t think where it would be useful, but it’s in
the docs as a supported option, so I suppose it must do something
