I've confused myself. I have three objects: level, product, part. Together they classify a repair type.
- Replacing a part in a product has a level of difficulty associated with it. - The same part replaced in a different product has a different level of difficulty. How can I model an association among these? I have created a join model, "Repair class," and connected all three using :has_many through. However, this does not prevent multiple records where the part and product stay the same, but the level changes. In other words, I end up with multiple levels assigned to the same part/product combination which does not happen in the real world. What's the best way to proceed?
