I am trying to change attribute of all objects in AR collection inside  
a map block  
see:

[http://pastie.org/329737](http://pastie.org/329737)

but attributes are not being updated in Rails 2.2

This was working in earlier versions of rails

Any help is appreciated

Here,

Anyway I guess you should call the save method on it like ‘user.save’.

Thanks,

First off, why use map when you could use each ?  
Secondly this looks related to what I wrote at  
[First, foremost and [0] - Space Vatican](http://www.spacevatican.org/2008/11/15/first-foremost-and-0) (although  
I don’t think that would account for your exact snippet)
