Transform array of arrays to array of hashes with new keys

Question

I have array of arrays like this:

status = [
   ["Deleted", "deleted", 0],
   ["In planning", "planning", 1],
   ["In approval", "approval", 2]
]

How do I transform it to an array of hashes like this?

[
  {:label => "Deleted", :value => "deleted"},
  {:label => "In planning", :value => "planning"},
  {:label => "In approval", :value => "approval"}
]

So far I tried:

status.each do |s| label: s[0], value: s[1] end

However, I don't get back an array of hashes. If I do:

puts s[0], value: s[1]

I see only hashes in my console:

{:label => "Deleted", :value => "deleted"}
{:label => "In planning", :value => "planning"}
{:label => "In approval", :value => "approval"}

I believe I somehow would need to add those hashes to the array.

@BlueSmith Thank you, it works :) I tried similar as well, but without .map — matiss

Try to the following:

status.map { |label, value, _| { label: label, value: value } }

status.map{ |s| Hash[label: s[0], value: s[1]] }
# => [{:label=>"Deleted", :value=>"deleted"}, {:label=>"In planning", :value=>"planning"}, {:label=>"In approval", :value=>"approval"}]
