My question is very simple, I have:
@users = User.first(100)
From the @users array, how can i get the user object with the id 50?

Use detect:
user = @users.detect { |u| u.id == 50 }
Though there are ways to fetch just one record (with id 50) if you don't need the remaining 99.

Thanks for your answer, do you think your answer is better? I've never read about detect.

You should check the link to its documentation. I don't know about
@users.find, how it works. But detect will iterate over the @users and when first element with matching condition is found, loop breaks and that element is returned.If you want to do an ActiveRecord find you can do:
@users = User.find_by_id(50)Or if you want to do an Array find you can do:
@users.find_all { |user| user.id == 50 }

Thanks for your answer, is very close of how I get it. Do you think your answer is better?
I have found a solution myself, but I'll wait until other people tell us which answer is better.
@users.find {|u| u.id == 50 }
Thanks for your answers!
