Adding a delete link for nested attributes

Question

I have nested attributes in my show.erb and I create a blank nested attribute and show a grid of items with the blank at the bottom like so.

<%= form_for          


        

Answer 1

Why do you want to use a link? You can also use the destroy functionality in the nested attributes.

All you need to do is to add :allow_destroy => true in your accepts_nested_attributes definition and add

<%= l.check_box '_destroy' %>

to each record. That way it removes all the nested records with the check-box checked when saving the record.
