Hey all,

I just upgraded a very simple rails based website from Rails 2.0.2 to  
2.2.2. When I started up Mongrel however, I got the following error:

Any help and pointers appreciated,

Hi All,

I found the following discussion on the group:  
[http://groups.google.com/group/rubyonrails-talk/browse\_thread/thread/ba1942467c19ea41/7b0a6ae9e87e8d49?hide\_quotes=no](http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/ba1942467c19ea41/7b0a6ae9e87e8d49?hide_quotes=no)

I now see this is a deprecated and now removed attribute. However, what  
I was wondering, isn’t running rake rails:update supposed to fix these  
issues. From Aptana it states that rails:update does the following:

Update both configs, scripts and public/javascripts from Rails

Seeing that the files that contained the removed attribute is in the  
config/environments folder I find it strange that the Rake command did  
not fix it or, am I misunderstanding what exactly the command does?

Thanks,  
Schalk

editing a user editable and often heavily modified file like  
production.rb would be somewhat error prone. As far as I can remember  
the only such file that is updated is boot.rb (which has a warning at  
the top saying ‘don’t change me’)

The following command is deprecated in Rails 2.2.2  
in config/environments/development.rb  
config.action\_view.cache\_template\_extensions = false
