I would like to write a few custom methods for my model, but keep
getting an error saying the method is not defined for the model (playing
in the console).
For example, I have a product model, and I want a method called stocked?
that will return ‘yes’ or ‘no’ depending on an in_stock boolean field
for the model:
class Product < ActiveRecord::Base
self.in_stock ? ‘yes’ : ‘no’
How would I fix this?..
