I am wondering how to merge these two arrays into one clean array in Ruby
Both arrays share one similar key:value pair. I am trying to merge information from these two separate arrays that have information for the same person. One array has his name. The other array has his job and age. Both arrays have an id matching to the same person.
An example of what I am trying to do
array1 = [ {:id => 1, :name => "Bob"}, {:id => 2, :name => "Tim"}]
array2 = [ {:id => 1, :job => "firefighter", :age => 25}, { :id => 2, :job => "accountant", :age => 30} ]
new_array = [ {:id=> 1, name => "Bob", :job => "firefighter", :age => 25}, { :id => 2, :name => "Tim", :job => "accountant", :age => 30} ]
You could do something like this:
new_array = array1.each_with_index.map { |x, i| x.merge array2[i] }
# => [{:id=>1, :name=>"Bob", :job=>"firefighter", :age=>25}, {:id=>2, :name=>"Tim", :job=>"accountant", :age=>30}]
If you want a solution that is not dependent on the order of the array, and instead uses the :id to match the hashes:
array1.map { |x| x.merge (array2.find { |h| h[:id] == x[:id] } || {}) }
