I've got an array in the following form:
[["First", ["a", "b", "c"]], ["Second", ["d", "e"]], ["Third", ["g", "h", "i"]]]
Is there a way to somehow display this information on a Rails template using iterators? I need something like this:
First - a, b, c
Second - d, e,
Third - g, h, i.
Or this is impossible and I should modify the initial array form?
Thanks in advance.
Without modifing the main array you could try with each_with_index inside each for the main array of arrays, then checking for the first value you can skip it and get the array of letters:
array = [["First", ["a", "b", "c"]], ["Second", ["d", "e"]], ["Third", ["g", "h", "i"]]]
array.each do |main|
main.each_with_index do |value, index|
next if index.zero?
p value
end
end
# => ["a", "b", "c"]
# ["d", "e"]
# ["g", "h", "i"]
Or if you want to access it as a hash it'd be easier:
array = [["First", ["a", "b", "c"]], ["Second", ["d", "e"]], ["Third", ["g", "h", "i"]]]
array.to_h.each do |_, value|
p value
end
# => ["a", "b", "c"]
# ["d", "e"]
# ["g", "h", "i"]
