Hello,  
I have a database table with a primary key not being a simple id but  
three columns. By overriding update() and create() I got Rails to work  
with that table quit good. Except for the destroy() action. From the  
resulting trace I can see that the old version of destroy() is called  
from transaction.rb. I think this lines might be the reason that I’m  
unable to override detroy():

from transaction.rb

```
 def self.append_features(base)
   super
   base.extend(ClassMethods)

   base.class_eval do
     alias_method :destroy_without_transactions, :destroy
     alias_method :destroy, :destroy_with_transactions

```

…

Any ideas, hints, etc.?

best regards,  
Torsten

Add on: My fault, I simply picked the wrong model class. Now with  
overloading update(), create() and destroy() in the right model class  
with natural primary keys every thing works as expected.
