I am new to CI and I am maintaining one project build in CI, previously developed by another guy.
This guy create his own MY_Model in application/core and all models he created extend that MY_Model.
I don't like the core model built by him and want to use Jamie Rumbelow's MY_Model instead in the other models I will create recently.
But since almost all the old models extended the MY_Model already, I can't just replace MY_Model.
How can I use Jamie Rumbelow's MY_Model' and still make old models work?
Thanks for any advices!
