ActiveRecord :: RecordNotFound: не удалось найти модель с ID = 62 для модели с ID = 2

Question

Не удалось найти MetricLocationHelper с идентификатором = 62 для Metric :: MetricDirector с идентификатором = 2

У меня есть has_and_belongs_to_many ассоциация, и мои модели

class MetricLocationHelper < ActiveRecord::Base
     has_and_belongs_to_many :metric_metric_directors, class_name: "Metric::MetricDirector", association_foreign_key: "metric_metric_director_id"
end

и

class Metric::MetricDirector < ActiveRecord::Base
   has_and_belongs_to_many :metric_location_helpers, foreign_key: 'metric_metric_director_id'

   accepts_nested_attributes_for :metric_location_helpers, reject_if: :all_blank, allow_destroy: true
end

Мои третьи столбцы таблицы:

• metric_metric_director_id
• metric_location_helper_id

А в контроллере

 def metric_director_params
   params.require(:metric_metric_director).permit(:name, :username, :region, metric_location_helpers_attributes: [:id, :_destroy])
end

У меня возникла проблема при обновлении и создании записи.

ActiveRecord :: RecordNotНайдено в метрике :: MetricDirectorsController # update

Не удалось найти MetricLocationHelper с ID = 62 для Metric :: MetricDirector с ID = 2

Обновлен код

class Metric::MetricDirectorsController < ApplicationController
  before_action :set_metric_director, only: [:show, :edit, :update, :destroy]

def new
  @metric_director = Metric::MetricDirector.new
  @locations = @metric_director.metric_location_helpers.build
end

def edit
  @locations = @metric_director.metric_location_helpers
end

def create
  @metric_director = Metric::MetricDirector.new(metric_director_params)

  if @metric_director.save
    redirect_to metric_metric_directors_path, notice: 'Director was successfully created.'
  else
    render :new
  end
end

def update  
  if @metric_director.update(metric_director_params)
  redirect_to metric_metric_directors_path, notice: 'Director was successfully updated.'
  else
    render :edit
  end
end


private

  def set_metric_director
    @metric_director = Metric::MetricDirector.find(params[:id])
  end


def metric_director_params
   params.require(:metric_metric_director).permit(:name, :username, :region, metric_location_helpers_attributes: [:id, :_destroy])

end

Ваша помощь очень ценится

Спасибо
