Converting an array of hashes to ONE hash in Ruby

Question

I have an array of hashes with arrays that look something like this:

result = [
  {\"id_t\"=>[\"1\"], \"transcript_t\"=>[\"I am a transcript ONE\"]},
          


        

Answer 1

I think the key to the solution is Hash[], which will create a Hash based on an array of key/values, i.e.

Hash[[["key1", "value1"], ["key2", "value2"]]]
#=> {"key1" => "value1", "key2" => "value2"}

Just add a set of map, and you have a solution!

result = [
  {"id_t"=>["1"], "transcript_t"=>["I am a transcript ONE"]},
  {"id_t"=>["2"], "transcript_t"=>["I am a transcript TWO"]},
  {"id_t"=>["3"], "transcript_t"=>["I am a transcript THREE"]}
]
Hash[result.map(&:values).map(&:flatten)]
