Where do I place the configuration for Act-as-taggable-on?

acts-as-taggable-on, ruby-on-rails, ruby-on-rails-3

Solution

You can create a custom initializer in `config/initializers` and put this line there.

Or alternatively, you can set this in `config/application.rb`:

module YourApp
  class Application < Rails::Application
    ActsAsTaggableOn.force_lowercase = true
  end
end

Problem

I'm reading the act-as-taggable Github document, https://github.com/mbleigh/acts-as-taggable-on, and I want to force tags to be saved downcase. The instruction in the Configuration section says to add the line `ActsAsTaggableOn.force_lowercase = true` but I'm not quite sure where this would go. In what file am I supposed to put this piece of code? Thanks!
