Question

I have an array of objects and I want to find which element in the array has a particular attribute equal to a value, specifically which element in this array has an object that has :parent_id equal to 55.

How can I do this?

Answer 1

To find the index:

 array.index{ |item| item.parent_id == 55 }

To find the item:

array.find{ |item| item.parent_id == 55 }
