Hi I've followed the documentation step by step but getting the above error while rendering the JSON.

Ruby 2.3.1 Rails 4.2.1 gem 'active_model_serializers', '~> 0.10.10'

Here is my datatable class

class SamsaraTripDatatable < AjaxDatatablesRails::ActiveRecord

  def view_columns
    @view_columns ||= {
      start_at: { source: "SamsaraTrip.start_at", cond: :date_range, delimiter: '-yadcf_delim-'},
      start_location: { source: "SamsaraTrip.start_location", cond: :like, searchable: true, orderable: true  }
    }
  end

  def data
    records.map do |record|
      {
        start_at: record.start_at,
        start_location: record.start_location
        DT_RowId:   record.id
      }
    end
  end

  def get_raw_records
    SamsaraTrip.all
  end

end

Here is my backtrace.

NoMethodError at /samsara_trips.json
