cache_key

Importance_1
cache_key() public

Returns a stable cache key that can be used to identify this record.

Product.new.cache_key     # => "products/new"
Product.find(5).cache_key # => "products/5"

If ActiveRecord::Base.cache_versioning is turned off, as it was in Rails 5.1 and earlier, the cache key will also include a version.

Product.cache_versioning = false
Product.find(5).cache_key  # => "products/5-20071224150000" (updated_at available)
