Question

Consider the below hash

[
{:rank => 3, :time => "3.00 AM" , :name => "JJJ"},
{:rank => 1, :time => "3.05 AM" , :name => "AAA"},
{:rank => 5, :time => "2.55 AM" , :name => "XXX"},
{:rank => 2, :time => "3.10 AM" , :name => "BBB"}
]

How do i sort the fields in an order, so that i will obtain result
as like query
(Consider if we fetch values in has is from a table)

select * from my_table order by rank, time, name 

Please comment if i am not clear.

Answer 1

a = [
{:rank => 3, :time => "3.00 AM" , :name => "JJJ"},
{:rank => 1, :time => "3.05 AM" , :name => "AAA"},
{:rank => 5, :time => "2.55 AM" , :name => "XXX"},
{:rank => 2, :time => "3.10 AM" , :name => "BBB"}
]
res = a.sort_by{|t| [t[:rank], t[:time], t[:name]]}
