instance method
==
Ruby on Rails edge
Since v4.0.13Signature
==(comparison_object)Returns true if comparison_object is the same exact object, or comparison_object
is of the same type and `self` has an ID and it is equal to `comparison_object.id`.
Note that new records are different from any other record by definition, unless the
other record is the receiver itself. Besides, if you fetch existing records with
`select` and leave the ID out, you're on your own, this predicate will return false.
Note also that destroying a record preserves its ID in the model instance, so deleted
models are still comparable.: (top) -> bool
