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

Question

我有一个Formtastic表单，并希望它在提示中显示一个链接，如果有的话。

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

Answer 1

The solution I found to solve this was to use f.object and 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
