nested_form for recursive Model

[viniciusfont]

I have this:
https://stackoverflow.com/questions/36960235/rails-nested-form-recursive

And the problem here is nested_form creating the partial recursively until exausts.
I think the problem is nested_form creating multiple blueprint for each partial.

How can I solve this problem? Thanks in advance!
