how can I eliminate duplicate elements from an array of ruby objects using an attribute of the object to match identical objects.
with an array of basic types I can use a set..
eg.
array_list = [1, 3, 4 5, 6, 6]
array_list.to_set
=> [1, 2, 3, 4, 5, 6]
can I adapt this technique to work with object attributes?
thanks
If you can write it into your objects to use
eql?then you can useuniq.
