API: mark - activescaffold/active_scaffold GitHub Wiki

Enable mark records in list. It will add a checkbox at each row to select the record, and a checkbox to select all records. Selected records will be stored in the session and you can get currently selected records with the controller method marked_records. You can get the marked records from the model with marked_records class method too, and check if a record is marked with as_marked method.

Example (don’t forget to add appropriate changes to routes.rb!):

class ModelsController < ApplicationController
  active_scaffold :model do |conf|
    conf.actions.add :mark
    conf.action_links.add :delete_selected, :type => :collection, :method => :delete
  end

  def delete_selected
    each_marked_record do |record|
      record.as_marked = false if record.destroy
    end
    head :ok # FIXME: You should delete it and write some js view or something else
  end
end

It allows to change which records will be marked on clicking mark all checkbox. Set to :page to mark all records in current page. By default is :search which will mark all records in the list, using current search conditions.
