After I patched my rails to allow me to use the “\<\<” operation on  
has\_many through WITH a self referential relationship, I ran into  
another issue:

:uniq=\> true does not prohibit me from creating a second record in the  
database.

Has anyone experienced this or has a work around? BTW, Im using Rails  
1.2.
