Hi,

I am running into a problem which really confuses me. I have Rails 2.1  
and friends installed on both my osx development machine and a gentoo  
linux machine.

I get a different ActiveRecord initialisation behaviour on those  
machines. Here is a console example:

OSX (IMHO correct behaviour):

Loading development environment (Rails 2.1.0)

> > Image.new.parent\_id  
> > =\> nil

Linux (IMHO wrong behaviour):

Loading development environment (Rails 2.1.0)

> > Image.new.parent\_id  
> > =\> 0

Image is an ActiveRecord using the attachment\_fu plugin (but that is  
not the problem).

Any ideas why this is happening???

Thanks

nikwest

Ok, as usual I solved it once I wrote the post.

The problem was that I had an older version of sqlite3-ruby (1.1) on  
my linux box. After updating to 1.2.2 it showed the same behaviour as  
on OSX …
