I am working on my first large rails app and had a quick question of
It is essentially an ERP type application, tracking customer accounts,
orders, and product inventory.
I am finding I am learning towards creating method libraries
containing certain areas of business logic that refer to multiple

modify existing resources, more make a decision based on some business
Pricing for example. Given the complexity of product pricing models
with customer specific pricing I was thinking of having some form of
pricing engine that given a customer and a product returned the price
I am also looking at doing similar things with despatch methods and so
Essentially encapsulating a number of business rules which do not
necessarily belong in the models.
Given the above I had considered creating modules within the lib

Does anyone know of a better ruby or rails specific way of modeling
