Hi guys,

In my "fooengine" mountable engine, I have subfolders within the app/
models/fooengine folder. For example:

In order to have these files loaded, I added:
config.autoload_paths += %W(#{config.root}/app/models/fooengine/
to lib/fooengine/engine.rb.

But it gives an error:
LoadError: Expected ... to define Foo
and indeed, the fully qualified name is FooengineFoo, not Foo so the
auto loader is lost.

It works if I rename all my model files to fooengine_(model name).rb,
but I guess there probably is a better way.

Do you know?

Thanks a lot!

Hi guys,

Answering my own question in case it helps others.

Devise is considered a kind of "reference" Engine, and the way they do
it is in lib/devise.rb, they use autoload for the classes defined in
their lib folder. For instance:

autoload :Delegator,     'devise/delegator'

It worked for me.
