How to return newest record in array

Question

I want to return the most recent record in an array according to message_date. How would i go about this? I have this piece of code returning all and have tried using last etc. but I'm not too sure what i'm doing.

contact_messages_threads(@customer.id).each do |openmessagethread|
  - @messagelast = openmessagethread.message_date

Not sure if I understand correctly. Is contact_messages_threads(@customer.id) or openmessagethread the array you want to find the newest record in? — IngoAlbers

@EgonWilzer contact_messages_threads is the method and I assume openmessagethread is the array. — user3385136

You should be able to get it like this if contact_messages_threads(@customer.id) returns the array:

@messagelast = contact_messages_threads(@customer.id).max_by(&:message_date)

For what? So openmessagethread is not the array? Can you try @messagelast = contact_messages_threads(@customer.id).max_by(&:message_date) ?

Got it. Thanks. Really confused matters. Thanks for clarifying. I thought contact_messages_threads was a method as I have defined it elsewhere.
