Customizing the Form

Active Admin gives complete control over the output of the form by creating a thin DSL on top of the fabulous DSL created by Formtastic (http://github.com/justinfrench/formtastic).

ActiveAdmin.register Post do

  form do |f|
    f.inputs "Details" do
      f.input :title
      f.input :published_at, :label => "Publish Post At"
      f.input :category
    end
    f.inputs "Content" do
      f.input :body
    end
    f.buttons
  end

end

Please view the documentation for Formtastic to see all the wonderful things you can do: http://github.com/justinfrench/formtastic

If you require a more custom form than can be provided through the DSL, you can pass a partial in to render the form yourself.

For example:

ActiveAdmin.register Post do
  form :partial => "form"
end

Then implement app/views/admin/posts/_form.html.erb:

<%= semantic_form_for [:admin, @post] do |f| %>
  <%= f.inputs :title, :body %>
  <%= f.buttons :commit %>
<% end %>
