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

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

without array block

Answer 1

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">

Answer 2

irb(main):005:0> arr = ["#"]
irb(main):006:0> elem = arr.first
irb(main):008:0> elem == "#"
=> true
