RoR free element from array

i have an element in a array such that,

[#<Name id: 23, first_name: "anderson", last_name: "gorge">]

how can i remove the array block, so that i want it as

#<Name id: 23, first_name: "anderson", last_name: "gorge">

Do you mean you have a single element in an array and you want to extract it? There so many ways of doing it, 2 that quickly come to mind are:

>> obj = [#<Name id: 23, first_name: "anderson", last_name: "gorge">].first
=> #<Name id: 23, first_name: "anderson", last_name: "gorge">
>> obj = [#<Name id: 23, first_name: "anderson", last_name: "gorge">].shift
=> #<Name id: 23, first_name: "anderson", last_name: "gorge">
