Sort the hash by value in descending order, and then type in ascending ruby

Question

I have a hash like this

trial_hash ={"key1"=>1000, "key2"=>34, "key3"=>500, "key4"=>500, "key5"=>500, "key6"=>500} 

I order it in descending order of value:

  my_hash = trial_hash.sort_by{|k, v| v}.reverse 

I get it like this:

  [["key1", 1000], ["key4", 500], ["key5", 500], ["key6", 500], ["key3", 500], ["key2", 34]] 

But I want it to be sorted in ascending order when the value is the same. How can I do it?

For example: the above hash will be ordered this way:

  [["key1", 1000], ["key3", 500], ["key4", 500], ["key5", 500], ["key6", 500], ["key2", 34]] 

Answer 1

When comparing, arrays are first evaluated by the first elements, then by their second, etc. You can use this fact to list successive comparisons. Comparison by [-v, k] first sorts by value (in reverse order), then by key.

 >> trial_hash.sort_by{|k, v| [-v, k]} => [["key1", 1000], ["key3", 500], ["key4", 500], ["key5", 500], ["key6", 500], ["key2", 34]]
