I have a hash like so:
list=[
{:cod => "0001", :name => "name1", :val => 10},
{:cod => "0001", :name => "name1", :val => 12},
{:cod => "0002", :name => "name2", :val => 13},
{:cod => "0002", :name => "name2", :val => 14},
{:cod => "0002", :name => "name2", :val => 14},
{:cod => "0004", :name => "name4", :val => 16},
{:cod => "0004", :name => "name4", :val => 16},
{:cod => "0004", :name => "name4", :val => 17},
{:cod => "0005", :name => "name5", :val => 17},
{:cod => "0005", :name => "name5", :val => 17},
{:cod => "0005", :name => "name5", :val => 17},
{:cod => "0006", :name => "name6", :val => 110},
{:cod => "0006", :name => "name6", :val => 10},
]
What I would like to learn how to do is how to remove a record if it is
duplicate end sum values :val.

Thanks for replay, but this solution only remove the duplication of values and sum of values duplication? Thanks again.

Botp, thanks for replay, this is solution:
list.inject(Hash.new(0)) { |hash, el| hash[el[:cod]] += el[:val] ; hash }
I want it out:
{"0006"=>120, "0005"=>17, "0004"=>33,
"0002"=>27, "0001"=>22}
Thanks for replay again.
