You can put shared functions (or classes) in a model file instead. I use modules for decoupled, reusable code, model files for coupled app-specfic shared code. You just have to get past the idea that just because they're called 'models' doesn't mean that's all they can contain. > > > > > On May 4, 1:49 pm, mdipierro <[email protected]> wrote: >> A module is a module.
