Hello,

I need to modelate a genealogical tree with:  
animal,Dam(Mother) and Sire(Father)

the Dam and Sire are Animals then i modelate this:

class Animal \< ActiveRecord::Base  
belongs\_to :sire  
belongs\_to :dam  
validates\_associated :sire, :dam  
end

class Sire \< Animal  
has\_many :animals  
end

class Dam \< Animal  
has\_many :animals  
end

then when i save a new animal the validate doesnt work like this:

i have the table Animals

ID, Name Father MOther  
1 A - -  
2 B - -

when I insert a new record like this

insert(3,C,1,2) its ok!  
insert(3,C,5,7) its ok too, (the validates is doesnt work)

how can i solve this??

Try the Rails mailing list  
[[http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails)] for this.

Also, I’m so ripping off the word “modelate”.
