Rails, ancestry gem, populating dropdown with two depth level
I installed ancestry gem successfully following instruction from https://github.com/stefankroes/ancestry and my Categories table look like this:
Categories(id, category_name, ancestry, created_at, updated_at)
I want to make select based on parent->sub-category->sub-sub-category:
At this point with code(taken from https://github.com/stefankroes/ancestry/wiki/Creating-a-selectbox-for-a-form-using-ancestry) i can only manage to get following which is not correct.
Solution
