How do I loop over a hash of hashes?

Question

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?

Answer 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 

Answer 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)
