How to sort a Ruby Hash by number value

Question

I have a counter hash that I am trying to sort by count  The problem I am running into is that the default Hash sort function sorts numbers like strings rather than by number size   i e  Given Hash   metrics     sitea com    gt  745   siteb com    gt  9   sitec com    gt  10     Running this code   metrics sort   a1 a2  a2 1  lt   gt a1 1     will return a sorted array      siteb com   9   sitea com   745   sitec com   10    Even though 745 is a larger number than 9  9 will appear first in the list  When trying to show who has the top count  this is making my life difficult      Any ideas on how to sort a hash  or an array even  by number value size   I appreciate any help

That s not the behavior I m seeing   irb main  001 0 gt  metrics     sitea com    gt  745   siteb com    gt  9   sitec com    gt   10     gt    siteb com   gt 9   sitec com   gt 10   sitea com   gt 745  irb main  002 0 gt  metrics sort   a1 a2  a2 1  lt   gt a1 1     gt     sitea com   745     sitec com   10     siteb com   9     Is it possible that somewhere along the line your numbers are being converted to strings   Is there more code you re not posting

Already answered but still  Change your code to   metrics sort   a1 a2  a2 1  to i  lt   gt  a1 1  to i     Converted to strings along the way or not  this will do the job

Since value is the last entry  you can do   metrics sort by  amp  last

No idea how you got your results  since it would not sort by string value    You should reverse a1 and a2 in your example  Best way in any case  as per Mladen  is   metrics     sitea com    gt  745   siteb com    gt  9   sitec com    gt  10   metrics sort by    key  value  value         gt     siteb com   9     sitec com   10     sitea com   745     If you need a hash as a result  you can use to h  in Ruby 2 0    metrics sort by    key  value  value  to h        gt    siteb com    gt  9   sitec com    gt  10   sitea com   745
