Add an Array of length x to value in key : value hash using Ruby

Question

Here is a hash

personal_details = {
  name: name,
  dob: dob,
  age: age,
  height: height
}

Here is an array

puts "What are the name of some of your relatives? (eg. Bob, James, Harry etc)"
relatives = gets().chomp.split(",")

Lets say the input for relatives was "Bob, James, Harry".

I want the hash to look like this:

personal_details = {
  name: name,
  dob: dob,
  age: age,
  height: height
  relatives: [
         {name: Bob},
         {name: James},
         {name: Harry}
  ]
}

The array in the hash is updated based on user input.

Start by initialising relatives as an array:

personal_details = {
  name: name,
  dob: dob,
  age: age,
  height: height,
  relatives: []
}

Then for each relative, push to the array:

relatives = gets().chomp.split(",")
relatives.each do |relative|
  personal_details.relatives.push(name: relative)
end

This worked personal_details[:relatives].push(name: relative)

This should work, if I've interpreted the question as intended:

personal_details[:relatives] = relatives.map{|r| {name: r}}
