Ruby 1.8: Hash#sort not return hash but array (better way to do this?) -

In some scenarios of Ruby 1.8, if I have hash

  # k, v Order fu = {"gym" => 1, "bar" = & gt; 1, "Joe" = & gt; 2} sorted_by_values ​​= foo.sort {| A, b A [1] & lt; ==> B [1]} #sorted_by_values ​​is an array of arrays, it is no longer a hash! My action is to create the rule  to_hash  for the Array class. 
 
  square array DEF    to_hash (& block) hash [* self.collect {| K, v | [K, v]}. Flaton] End End  
 
 I can then do the following: 
 
  sorted_by_values.to_hash.keys.join ','  
 
 Is there a better way to do this? 
 

There is no such thing as anarchold sorted hash by the hashas definition, your best The condition is probably possible to collect keys from the collected array and then add one to the result

  sortedByValues ​​= foo.sort {| A, b A [1] & lt; ==> B [1]} Sorted Belgian Colllect {| A. A [0]}. Insert ','
