How do I loop over a hash of hashes?
I have this hash:
h
=> {"67676.mpa"=>{:link=>"pool/sdafdsaff", :size=>4556}}
> h.each do |key, value|
> puts key
> puts value
> end
67676.mpa
linkpool/sdafdsaffsize4556
How do I access the separate values in the value hash on the loop?
Solution 1:
Value is a Hash to so you need iterate on it or you can get only values:-
h.each do |key, value|
puts key
value.each do |k,v|
puts k
puts v
end
end
or
h.each do |key, value|
puts key
value.values.each do |v|
puts v
end
end
Solution 2:
You'll want to recurse through the hash, here's a recursive method:
def ihash(h)
h.each_pair do |k,v|
if v.is_a?(Hash)
puts "key: #{k} recursing..."
ihash(v)
else
# MODIFY HERE! Look for what you want to find in the hash here
puts "key: #{k} value: #{v}"
end
end
end
You can Then take any hash and pass it in:
h = {
"x" => "a",
"y" => {
"y1" => {
"y2" => "final"
},
"yy1" => "hello"
}
}
ihash(h)
