I started to use formstatic but I need to make a file field with image preview. I mean, when i edit an object, i want to see the image already linked.
How can I do that?
Thank you !
The answer is to use the hint attribute :
ActiveAdmin.register Event do
form :html => { :enctype => "multipart/form-data" } do |f|
f.input :map, :as => :file, :hint => f.template.image_tag(f.object.map.url(:thumb))
end
end
Bye
