How to order matrix blocks in reverse

Question

I've using a matrix field from the same entry in two different templates. In one template I want them in the order they're displaying in the CMS, while in the other I want them displayed in reverse.

It doesn't like this:

{% for cta in entry.ctas.order('desc') %}

Can this be done any other way?

Answer 1

I went and looked at the MatrixBlockModel; there's an attribute named sortOrder (If you output {{sortOrder}} inside the for loop, it will display the index of that block).

You can use that attribute to sort by, in reverse:

{% for cta in entry.ctas.order('sortOrder desc') %}
