Hi All

I have a model defined as follows:

class a\< ActiveRecord::Base  
has\_many :a\_b\_mappings  
has\_many :bs, :through =\> :a\_b\_mappings, :uniq =\> true

has\_many :a\_c\_mappings  
has\_many :cs, :through =\> :a\_c\_mappings, :uniq=\> true

has\_many :a\_d\_mappings  
has\_many :ds, :through =\> :a\_d\_mappings, :uniq =\> true

…

end

I’m trying to find a class method that will enumerate all the classes  
(:bs,:cs,:ds,…) being associated from class a.  
I’m at a loss as to what hooks ActiveRecord provides that would enable  
me to do that.

Thanks much  
Kretch
