Sounds like you need to break the logic into modules instead of having them
all in the models folders that is kind of bad design. And module can be
imported into a conditional model file when needed which will make it
accessed to all actions in the controller that needs them. You can also
make cold only load for specific actions.
Remember just by putting the code in a model it is loaded every time. Where
as if you move the same code into a module it is only loaded when you need
it.
