Rails嵌套表单未插入数据库（Oracle）

Question

我有clients_controller与stores相关联。插入数据时，仅将其插入clients表中，而不会插入stores表中。如何在存储表中插入数据。 client_code是表之间的外键关联。

client.rb

class Client < ActiveRecord::Base
  extend FriendlyId
  has_paper_trail

  self.table_name = "DIM_CLIENT"
  self.primary_key = "client_code"
  self.sequence_name = :autogenerated


  has_many :stores, class_name: 'Store', foreign_key: 'client_code', dependent: :destroy
  accepts_nested_attributes_for :stores, allow_destroy: true, reject_if: :stores_blank
  validates_associated :stores

  validates :client_name, presence: true, uniqueness: {case_sensitive: false}
  validates :client_code, presence: true, uniqueness: {case_sensitive: false}
  after_save :set_default_store

  friendly_id :client_code


end

store.rb

class Store < ActiveRecord::Base
  extend FriendlyId
  has_paper_trail

  self.table_name = "DIM_STORE"
  self.primary_key = "store_id"
  self.sequence_name = :autogenerated

  belongs_to :client, class_name: 'Client', foreign_key: 'client_code'


  validates :store_name, presence: true, uniqueness: { case_sensitive: false }
  validates :store_id, presence: true, uniqueness: { case_sensitive: false }
  validates :client, presence: false

  friendly_id :store_id


end

clients_controller.rb

    class ClientsController < ApplicationController
  protect_from_forgery with: :null_session, if: Proc.new {|c| c.request.format == 'application/json'}
  before_filter :authenticate_user!, :is_admin
  before_action :set_client, only: [:show, :edit, :update, :destroy, :set_default_store, :update_default_store]

  # GET /clients/new
  def new
    @client = Client.new
    @store = Store.new
    3.times {@client.stores.build}
  end

  # POST /clients
  # POST /clients.json
  def create
    @client = Client.new(client_params)
    respond_to do |format|
      @client.valid?
      if @client.save
        format.js
      else
        @store = Store.new
        3.times {@client.stores.build}
        format.js {render "clients/new"}
        format.json {render json: @client.errors, status: :unprocessable_entity}
      end
    end
  end

  def create_success
    redirect_to request.referrer, notice: 'Client was successfully created.'
  end

  # PATCH/PUT /clients/1
  # PATCH/PUT /clients/1.json

  def set_default_store
    @stores = @client.stores.all.map {|store| store.code}.sort
  end

  def update_default_store
    if @client.update(update_default_store_params)
      redirect_to request.referrer, notice: 'Default Store successfully updated.'
    else
      redirect_to request.referrer, alert: 'Default Store could not be updated, Please contact support team.'
    end

  end

  private

  def set_client
    @client = Client.friendly.find(params[:id])
  end

  def client_params
    params.require(:client).permit(:client_name, :client_code, :enterprise_code, stores_attributes: [:id, :store_name, :store_id, :_destroy])
  end

  def update_default_store_params
    params.require(:client).permit(:default_store)
  end

end
