gistfile1.rb

Use : hash.invert.invert

Fuck what is wrriten below
 hash = {"0"=>{"name"=>"app1103key1", "value"=>"app1103value1", "_destroy"=>"true", "id"=>""}, "1"=>{"name"=>"version102key2",
 "value"=>"version102value2"}, "2"=>{"name"=>"version102key1", "value"=>"version102value1"}, "3"=>{"name"=>"version102profile2key1", "value"=>"version102profile2value1"}, "4"=>{"name"=>"app1-103profilekey1", "value"=>"app1-103profilevalue1"}, "5"=>{"name"=>"app1-103profilekey1", "value"=>"app1-103profilevalue1"},"6"=>{"name"=>"version102key1", "value"=>"version102value1"}}

merged_list = {}
hash.values.each do |item|
  if merged_list.has_key? item['name']
    merged_list[item['name']].merge! item
  else
    merged_list[item['name']] = item
  end
end
my_array = merged_list.collect { |k, v| v }

required_hash = Hash[hash.keys.zip(my_array)].reject!{|k,v| v.nil?}  
puts required_hash
