Problem upgrading from Rails 2.0.2 to 2.2.2

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:

** Starting Rails with development environment...
ExitingC:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/initializer.rb:530:in `send': undefined method `cache_template_extensions=' for ActionView::Base:Class (NoMethodError)

Any help and pointers appreciated,

Hi All,

I found the following discussion on the group:

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?

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
