Missing models after generating an Engine

Hi all !

I am extracting chunks of code into engines from an existing app. One
model I’m extracting is Recipient.

I followed the LoginEngine convention:

app/models/recipient.rb:
class Recipient < AR::Base
include XlPop::Recipient
end

lib/xl_pop/recipient.rb
module XlPop
module Recipient
def self.included(base)
base.send :include, XlPop::Recipient::InstanceMethods
base.send :extend, XlPop::Recipient::ClassMethods
base.validates_presence_of …
end

module ClassMethods
  ...
end

module InstanceMethods
  ...
end

end
end

The other models I extracted worked correctly, but loading Recipient
complains:

$ ruby script\console
Loading development environment.
./script/…/config/…/config/…/vendor/rails/activerecord/lib/…/…/activesupport/lib/active_support/dependencies.rb:123:in
`const_missing’:NameError: uninitialized constant Recipient

I added some code to
vendor/rails/activesupport/lib/active_support/dependencies.rb to show
me what files were loaded and the load path at that time. I noticed
that vendor/plugins/xl_pop/app/models is NOT in the load path. Is
that to be expected ?

I did try creating my model in app/models, and it works. So, I am
inclined to think the missing models directory in the load path is the
problem.

Thanks all !

Are you definitely ‘starting’ the engine?
