I have read that you could turn of time stamped migrations by adding  
the line “config.active\_record.timestamped\_migrations = false” to your  
environment.rb. After I add this line I get the following error when  
running “script/generate model Post”:

/Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/  
base.rb:1667:in `method_missing': undefined method`timestamped\_migrations=’ for ActiveRecord::Base:Class (NoMethodError)

Am I mistaken about this feature?

If I’m not mistaken about this feature has anyone else run into this?  
(I’d like to confirm before taking the next step.)

Thanks.  
Mike

I found it detailed in this ticket  
[http://dev.rubyonrails.org/ticket/11458](http://dev.rubyonrails.org/ticket/11458)  
and here  
[http://dev.rubyonrails.org/attachment/ticket/11458/timestamped-migrations.diff?format=txt](http://dev.rubyonrails.org/attachment/ticket/11458/timestamped-migrations.diff?format=txt)  
but I guess it didn’t make it in to 2.1.
