Instance Method Details

#clone_with_immunio ⇒ Object

ActiveRecord will “spawn”, or clone, relations under many circumstances. For example, #where will first spawn the relation, then add the where clause to the new relation, then return the new relation. This is so you can do something like:

prods = Product.where(cost: 10)

# Return blue products costing $10 prods_blue = prods.where(color: ‘blue’).to_a

# Return count of all products costing $10 prods_count = prods.count

We must track the prods relation and the relations returned by the color where call separately.
