Hello all,

I’m inserting records from another system and it looks something like  
this:

Model.create :id=\>123, :name=\>“asdf”

I noticed that the id attribute is ignored (the database will  
automatically assign an auto\_increment id starting from 1).

I remember reading about this before: iirc this is done so that you can  
easily fill in model information from forms, but I can’t find any  
documentation on this now.

Is there a way to force the id? Or do I have to do:

m = Model.new( :name=\>“asdf” )  
m.id = 123  
m.save

Thanks.

I’d suggest you leave id as an auto-increment and create a new field  
(oldsystem\_id or something).
