Active Admin add + button

Question

I have a model Post which have two attributes title - data-type string and description - data-type array

ActiveAdmin.register Post do
   permit_params :title, :description

   form do |f|
    f.inputs do
      f.input :title
      f.input :description
    end
    f.actions
  end

end

1. Value of title is saving properly but value of description is not saving through the form. How to save array field?

2. Can I put Add more button for description in active admin?

Answer 1

尝试更改名称以接受数组

f.input :description, input_html: { name: 'description[]' }
