# controller:
def show_all_models
  # require all of your models so they get loaded
  Dir.glob(RAILS_ROOT + '/app/models/*.rb').each { |file| require
file }
  # find all subclasses of ActiveRecord
  @all_models = Object.subclasses_of(ActiveRecord::Base)
end

# view:
<ul>
  <% @all_models.each do |model| %>
    <li><%= model %></li>
  <% end %>
</ul>

if you are using ActiveRecordStore there is probably a model in there
for that as well. if you don't want to display that one, remove it
inside your controller.
