Information Corner

We get a situation where we fetch some set of records from db as an array of hashes, and later we need to sort this array based on some field of DB.

Here is a very hand code to do so.

array_objs =[ {:title => "row1_title" ,:name => "Mumbai"},
              {:title => "row2_title" ,:name => "Delhi"},
              {:title => "row3_title" ,:name => "Bangalore"}  ]

array_objs .sort_by  {|array_objs|   array_objs [:name] }.each do |res|
  puts “#{res[:name] }”
end

O/P:
Bangalore
Delhi
Mumbai
