You have not told us what your fundamental problem is, so it is
difficult to say. You have just said you want to display all the
categories so something like
Category.all.each do |category|
# show data for category
end
However since I am telepathic I am guessing that what you actually
want to do is show the categories for each parent, which sounds pretty
much like user/micropost relationship in the tutorial. The clue here
is in the words "each parent". Don't start with the categories and
try to group them with the parents, start with the parents and work
down, so maybe
Parent.each do |parent|
# show parent data
parent.categories.each do |category|
# show category data
end
end
