Hello

When I try the command:  
rake db:migrate  
I get the following:

rello@calimero:~/Sites/music\_library/config$ rake db:migrate  
(in /home/rello/Sites/music\_library)  
rake aborted!  
undefined method `partial\_updates=’ for ActiveRecord::Base:Class

I googled with no results.  
Anybody can help me?  
Thankyou

Solved

It was an issue of Rails Vers. 2.0.2.9216

I just removed and everything works again.

You need to remove the edge gem (the one that looks like rails  
2.0.2.9216)

If you’re using Aptana, this is a problem that you may run into  
frequently  
as that ide adds [gems.rubyonrails.org](http://gems.rubyonrails.org) to your sources [without informing  
so]. [http://forums.aptana.com/viewtopic.php?p=20485](http://forums.aptana.com/viewtopic.php?p=20485) has more information  
about this. Hope it helps.

Check again; the tooth fairy didn’t stick that in your config. You had  
rails 2.0.2.xxx installed at the point that you ran rails my\_app.  
Remove the app, remove the gem and start afresh.
