…e active admin page has the 'belongs_to' statement.

I needed to implement this change in order to get a reference of the parent resource within a proc passed to the before_batch_import option in order to insert additional information to each line.

before_batch_import: Proc.new{|importer|         
      _form = importer.model.parent
       importer.csv_lines.each do |line|
         line.push _form.id
         line.push _form.generate_registration_code
       end
 }

I was not sure where and how to document this change.

What do you think about this proposal?

@ricardojudo , for new features to merge there is a requirement to add spec here https://github.com/activeadmin-plugins/active_admin_import/blob/master/spec/import_spec.rb

@ricardojudo , why not
if parent? instead of defined?(parent).nil?
