Problem
When using a nested (or embedded) scaffold in ActiveScaffold with Rails 2.3.2 you have the error:

undefined method `render_component'

Solution
According to the issue here, in Rails 2.3 the render_component has been removed.

Install the render_component from:

script/plugin install git://github.com/lackac/render_component.git -r rails-edge

and restart your server, and it should be working.

undefined method `cache_template_loading=’ for ActionView::Base:Class

Problem
While developing on Rails 2.3.2 you want to deploy in dreamhost that uses 2.2.2 at the moment.

Solution
Although we could try to freeze the specific rails version we are using, it’s probably easier as a temporary solution, until dreamhost upgrades the rails version to do the following:

  • Make sure that we have the following line with the appropriate version of 
    • RAILS_GEM_VERSION = '2.2.2' unless defined? RAILS_GEM_VERSION

    in the config/environment.rb file

  • Rename the application_controller.rb file back to application.rb
  • Comment out the following line from config/environments/production.rb
    • config.action_view.cache_template_loading = true
