Question

I have an array of users who are managers.

However there are repeated Users.

I would like to group them so that there is only one instance of each User in the array.

What would be the best way to go about this?

@managers.sort_by{|obj| obj.id} # Just sorted the data but did not eliminate duplicats

@managers.group_by{|u|u.name}    # just created a bunch of arrays for each name

Answer 1

Use the uniq method, which returns a new array with duplicates removed.

@managers.uniq
