ID: ruby-best-practices/identity-comparison
Language: Ruby
Severity: Info
Category: Best Practices
In Ruby, the rule “Prefer equal?
over ==
when comparing object_id
” is important to remember because of how these two comparison methods function. The equal?
method checks if the two compared references point to the exact same object, while the ==
method checks if the values of the two objects are the same.
This rule is crucial because when you are comparing object_id
, you are actually interested in whether the two objects are the same object, not whether their values are equal. Using ==
can lead to unexpected results if two different objects have the same object_id
.
To adhere to this rule and maintain good coding practices, always use equal?
when comparing object_id
. This ensures that you are accurately checking if the two objects are the same. For instance, instead of writing foo.object_id == bar.object_id
, you should write foo.equal?(bar)
. This way, you are properly checking for object identity, not object equality.
foo.object_id == bar.object_id
foo.equal?(bar)
