Split an array of hashes in two based on the value of a key

arrays, ruby

Solution

Use the `Enumerable#partition` method:

array.partition { |x| x[:ate] }
# => [[{:name=>"Gad", :ate=>true}, {:name=>"Bad", :ate=>true}], 
#     [{:name=>"Lad", :ate=>false}, {:name=>"Sad", :ate=>false}]]

Or:

array_1, array_2 = array.partition { |x| x[:ate] }

array_1
# => [{:name=>"Gad", :ate=>true}, {:name=>"Bad", :ate=>true}]

array_2
# => [{:name=>"Lad", :ate=>false}, {:name=>"Sad", :ate=>false}]
