Question

I’ve spent a few hours trying to figure out how to install a plugin in Rails 3 (probably the time it wouldve taken me to build the plugin myself). So rather than wasting more time,I’m hoping someone can simply explain how I can incorporate plugins in the vendor/plugins folder (which I’ve unzipped there) into an application. The installation instructions for Rails 2 are below:

Then you need to copy the configuration files, database migration and UI files into your application like so:

./script/generate install_has_threaded_comments

Answer 1

Rails 3.2 has deprecation warnings for using vendor/plugins and advocates adding gems to your Gemfile for everything.

gem 'acts_as_commentable_with_threading'

Rails 3 converts Rails 2’s script/generate (or script/anything) to:

rails generate acts_as_commentable_with_threading_migration
