How do I make this:

Into this:

["ford|white", "honda|blue"].collect do |str|
  ary = str.split('|')
  { 'make' => ary[0], 'color' => ary[1] }
end

gives me

[{"color"=>"white", "make"=>"ford"}, {"color"=>"blue", "make"=>"honda"}]

Without thought:

 > l = ["ford|white", "honda|blue"]
 > m = l.collect { |m| make, color = m.split('|'); { make: make, color: color } }
=> [{:make=>"ford", :color=>"white"}, {:make=>"honda", :color=>"blue"}]

(Using symbols for keys, generally recommended, IMO.)

input = ["ford|white", "honda|blue"]
input.map do |car|
  Hash[ %w(make color).zip car.split('|') ]
end
=> [{"make"=>"ford", "color"=>"white"}, {"make"=>"honda", "color"=>"blue"}]

This should do it

yourarray = ["ford|white", "honda|blue"]
yourhash = yourarray.map {|x| y = x.split('|'); {"make" => y[0], "color" => y[1]}}
