Convert and modify ruby hash to new hash - ruby

Question

How could I convert my hash to 2 very different hashes?
My hash:
{ "grey"=> ["421_01.jpg", "421_02.jpg", "421_03.jpg"],
"heather blue"=> ["422_01.jpg", "422_02.jpg", "422_03.jpg"],
"indigo"=> [],
"dark grey"=> ["435_01.jpg", "435_02.jpg", "435_03.jpg"] }
1. Desired hash: (all values from my hash)
[{ src: "421_01.jpg" },
{ src: "421_02.jpg" },
{ src: "421_03.jpg" },
{ src: "422_01.jpg" },
{ src: "422_02.jpg" },
{ src: "422_03.jpg" },
{ src: "435_01.jpg" },
{ src: "435_02.jpg" },
{ src: "435_03.jpg" }]
2. Desired hash:
[{
image: "421_01.jpg, 421_02.jpg, 421_03.jpg",
attributes: [
{
name: "Color",
option: "grey"
}
]
},
{
image: "422_01.jpg, 422_02.jpg, 422_03.jpg",
attributes: [
{
name: "Color",
option: "heather blue"
}
]
},
{
image: "",
attributes: [
{
name: "Color",
option: "indigo"
}
]
},
{
image: "435_01.jpg, 435_02.jpg, 435_03.jpg",
attributes: [
{
name: "Color",
option: "dark grey"
}
]
}]
Please note: empty array in my hash shouldn't add any images to color variation, but should add variation with empty image string. (All shown in examples)

Answer 1

h = { "grey"=> ["421_01.jpg", "421_02.jpg", "421_03.jpg"],
"heather blue"=> ["422_01.jpg", "422_02.jpg", "422_03.jpg"],
"indigo"=> [],
"dark grey"=> ["435_01.jpg", "435_02.jpg", "435_03.jpg"] }
a = h.values
#=> [["421_01.jpg", "421_02.jpg", "421_03.jpg"],
# ["422_01.jpg", "422_02.jpg", "422_03.jpg"],
# [],
# ["435_01.jpg", "435_02.jpg", "435_03.jpg"]]
For #1:
a.flat_map { |s| { src: s } }
#=> [{:src=>"421_01.jpg"}, {:src=>"421_02.jpg"}, {:src=>"421_03.jpg"},
# {:src=>"422_01.jpg"}, {:src=>"422_02.jpg"}, {:src=>"422_03.jpg"},
# {:src=>"435_01.jpg"}, {:src=>"435_02.jpg"}, {:src=>"435_03.jpg"}]
For #2:
h.map { |k,_| { image: a.shift.join(', '),
attributes: [{ name: "Color", option: k }] } }
# => [{:image=>"421_01.jpg, 421_02.jpg, 421_03.jpg",
:attributes=>[{:name=>"Color", :option=>"grey"}]},
{:image=>"422_01.jpg, 422_02.jpg, 422_03.jpg",
:attributes=>[{:name=>"Color", :option=>"heather blue"}]},
{:image=>"", :attributes=>[{:name=>"Color", :option=>"indigo"}]},
{:image=>"435_01.jpg, 435_02.jpg, 435_03.jpg",
:attributes=>[{:name=>"Color", :option=>"dark grey"}]}]
