Loading a Codeigniter model from another application

Question

I am trying to load a Codeigniter model from another application. I know this can be done easily with HMVC but using that technique means all modules should be in the same /application directory, as far as I am aware.

The folder structure I have is similar to this:

document_root
  - my_app/
    - application/
      - controllers/
      - models/
  - application/
    - controllers/
    - models/

I have a model in /my_app/application/models/ that I want to load from a controller in /application/controllers . Is it possible to go about doing this?

This is a bit tricky. I found another answer on SO with the possible solution:

Your best bet is to use symlinks if you can and link them into a sub-directory of your models directory. This would be simple and clean.

Barring that, you should extend Loader and overwrite the &model method to look in the secondary directory (perhaps reassign $path to the alternate application's model folder if $path == 'frontend').

If that also isn't an option, loading is done through APPPATH.'models/'.$path . '/' .$model.EXT. This means you can access the model by the relative path to APPPATH.'models/'. Don't do that if you can possibly avoid it, however. It is non-obvious and an invitation to errors.
