How to get the input value on Formtastic's hint?

Question

I have a Formtastic form and would like it to display a link in the hint if there's one.

f.input :link, hint: 'link here'

Answer 1

The solution I found to solve this was to use f.objectand then call the attribute link on it, like so:

  form do |f|
    f.inputs do
      f.input :link, hint: link_to(f.object.link, f.object.link)
    end
    f.actions do
      f.action :submit
    end
  end
