How can I fetch last row of the array in Ruby on rails?

Question

<%= m.members %>

This gives back this array below. If I want to get only last row of this array(Ray's record), how can I code?

[#<User id: 4, username: "John", age: 27, deleted_at: nil>, 
#<User id: 8, username: "Mike", age: 27, deleted_at: nil>,
#<User id: 13, username: "Ray", age: 27, deleted_at: nil>]

[#<User id: 4, username: "John", age: 27, deleted_at: nil>, 
#<User id: 8, username: "Mike", age: 27, deleted_at: nil>,
#<User id: 13, username: "Ray", age: 27, deleted_at: nil>].last

If we want to get the last and first elements as follows:
Ex: arr = [1,2,3,4]
$> arr.last => 4
$> arr.first => 1

please write .inspect after that.

The default to_s method for Array is the same as inspect in Ruby 1.9. An individual element's to_s method may be different. You shouldn't be dumping raw records into your HTML anyway, but instead accessing specific properties. to_yaml or to_json often provides a more readable output.

Also: [1,2,3,4][-1] #=> 4
