Instance Method Details

#get_sorted_objects(params, options = {}) ⇒ Object

Users can also pass in optional conditions that are used by the finder method call. For example if only wanted to show the items that had a certain status value you could pass in a condition ‘mytable.status == 300’ for example as the conditions parameter and when the finder is called the sortable table will only display objects that meet those conditions. Additionally you can paginate and sort the objects that are returned and apply the conditions to them.
