Are your saves working?

unless object.save  
raise :Yikes  
end

Perhaps your model isn’t validating?

Are you saying that you change the model’s ID and that the save does  
not update the ID of the record ?

I’m not sure that changing the ID is supported.

Check the log to see what gets saved.

Hope that helps !

Is your ID column set to auto-increment?

What is happening is that when i do:

m = Model.new  
m.description = ‘Another test’  
puts ‘Work fine’ if m.save  
puts ‘The attribute ID wasn’t updated’ if m.id.nil?  
m = Model.find(:first, :order =\> ‘id desc’ )  
puts m.description

The output is:  
$: Work fine  
$: The attribute ID wasn’t updated  
$: Another test

The record was inserted but the model object wasn’t updated with the  
id of the new record.
