Inspect all models in a Rails application
Quick Tip: Find all models in a project that include a certain method.
Useful for some engine applications. When you don't know what the parent application has you can do things like:
# if cache_classes is on - you need to do this # call first - otherwise you'll only get models # that have been touched/initialized Rails.application.eager_load! models = ActiveRecord::Base.descendants # find all models that have :users models.select {|m| m.new.respond_to?(:users) }
