How to check if a specific key is present in a hash or not

0 votes

I want to check whether the "user" key is present or not in the session hash. How can I do this?

Note that I don't want to check whether the key's value is nil or not. I just want to check whether the "user" key is present.

Hello @kartik,

While Hash#has_key? gets the job done, as it has been deprecated in favour of Hash#key?.

hash.key?(some_key)

Hope it helps!!

Thank You!!
