Convert Array of objects to Hash with a field as the key

I have an Array of objects:

[  #<User id: 1, name: "Kostas">,  #<User id: 2, name: "Moufa">,  ...]

And I want to convert this into an Hash with the id as the keys and the objects as the values. Right now I do it like so but I know there is a better way:

users = User.all.reduce({}) do |hash, user|  hash[user.id] = user  hashend

The expected output:

{  1 => #<User id: 1, name: "Kostas">,  2 => #<User id: 2, name: "Moufa">,  ...}
