Is there any way to use formtastic in activeadmin batch action form?

Question

According to activeamdin document, we can do:

batch_action :flag, form: {
type: %w[Offensive Spam Other],
  reason: :text,
  notes:  :textarea,
  hide:   :checkbox,
  date:   :datepicker
} do |ids, inputs|
  # inputs is a hash of all the form fields you requested
  redirect_to collection_path, notice: [ids, inputs].to_s
end

However, the above form is not formtastic and doesn't support advanced table configuration(set the size for the form window). Is there any way that I can change it to formtastic format like:

form do |f|
  f.semantic_errors # shows errors on :base
  f.inputs          # builds an input field for every attribute
  f.actions         # adds the 'Submit' and 'Cancel' buttons
end

Answer 1

Probably not. The form is built in batch_action_form.rb but rendered dynamically by the front end in modal_dialog.js.coffee, which is currently using jQuery. It is possible to get creative rewriting batch action forms but I can't recommend it. If your batch actions are complex try seeing if Custom Pages can meet your needs.
