Rails-散列数组中的带状键

Question

I have an array of hashes I'm submitting in a form. I'm pre-pending a unique key to the beginning because the names of the fields are the same and I needed to stop them over-writing each other. But when I save the data serialized in a field, I don't need the key anymore, so I'm looking for the best way to take it out:

{"6"=>{"Between Wires"=>"0"},
 "7"=>{"Wires to GND"=>"0"},
 "8"=>{"Between Wires"=>"0"},
 "9"=>{"Wires to GND"=>"0"},
 "10"=>{"Between Wires"=>"0"},
 "11"=>{"Wires to GND"=>"0"},
 "13"=>{"Between Wires"=>"0"},
 "14"=>{"Wires to GND"=>"0"},
 "16"=>{"Between Wires"=>"0"},
 "17"=>{"Wires to GND"=>"0"},
 "19"=>{"Between Wires"=>"0"}}

How can I remove the keys so I have this?

{{"Between Wires"=>"0"},
 {"Wires to GND"=>"0"},
 {"Between Wires"=>"0"},
 {"Wires to GND"=>"0"},
 {"Between Wires"=>"0"},
 {"Wires to GND"=>"0"},
 {"Between Wires"=>"0"},
 {"Wires to GND"=>"0"},
 {"Between Wires"=>"0"},
 {"Wires to GND"=>"0"},
 {"Between Wires"=>"0"},
 {"Wires to GND"=>"0"}}

Answer 1

It's been already answered, but I believe a better solution would be to use #values

hash = {
 "6"=>{"Between Wires"=>"0"},
 "7"=>{"Wires to GND"=>"0"},
 "8"=>{"Between Wires"=>"0"}
}

hash.values

Answer 2

You can iterate over them with map and leave out the key.

old = {"6"=>{"Between Wires"=>"0"}, "7"=>{"Wires to GND"=>"0"}}
new = old.map { |k,v| v }
