File upload with Activeadmin Rails using paperclip

Question

I use Active admin as my rails application backend. I want to make a file upload. How can I accomplish this functionality?

Answer 1

In latest Version of ActiveAdmin & Rails 6 for displaying the file field we need to use the below code

ActiveAdmin.register Project do
  permit_params :name, :uploads
  

  form multipart: true do |f|
    f.inputs "Project Details" do
      f.input :name
      f.input :uploads, as: :file, required: false
    end
    f.actions
  end

end

In some old version of AA following code also worked.

f.input :uploads, required: false
