POST-запрос не позволяет базе данных достаточно долго генерировать ID

Question

Мой почтовый запрос к моему rails-api не дает достаточно времени для генерации моего вторичного идентификатора.Когда я использую setState в родительском контейнере в функции axios.post (функция addNewLoad), мой delivery_id (пользовательский дополнительный идентификатор в базе данных) возвращает null в this.state.apiData.

Если я обновляю страницу, delivery_id заполняется ПРАВИЛЬНЫМИ данными, но мне нужно, чтобы данные были правильными, когда я возвращаю response и использую setState в запросе POST.

Я понятия не имею, что происходит!

Родительский контейнер, в котором я использую axios для GET и POST:

export default class PickupDeliveries extends Component {
    state = {
        apiData: [],
    }

    componentDidMount(){
    // gets all the pickup/deliveries
        axios.get('http://localhost:3001/api/v1/pickup_deliveries')
            .then((response) => {
                console.log(response);
                this.setState({
                    apiData: response.data})
                })
            .catch((error)=>{console.log(error);});
    }

    addNewLoad = (pickup_date, pickup_location, rate, delivery_date, delivery_location, local, loaded_miles, deadhead_miles, delivery_id, pickup_zip, delivery_zip) => {
        let config = {
            headers: {
                'Content-Type': 'application/json; charset=utf-8', "Accepts": "application/json",
            }
        }
     const instance = axios.create({baseURL: 'http://localhost:3001'})
            instance.post('/api/v1/pickup_deliveries', {pickup_date, pickup_location, rate, delivery_date, delivery_location, local, loaded_miles, deadhead_miles, delivery_id, pickup_zip, delivery_zip}, config)
            .then(response => {
                this.setState({apiData: [ ...this.state.apiData, response.data ] })

            })
            .catch(error => {
                    console.log(error)
            })
    }

Это дочерний компонент, который использует this.props.addNewLoad для отправки данных формы:

    handleSubmit = (e) => {
        e.preventDefault()
        this.props.onNewLoad(
          this.state.pickup_date, 
          this.state.pickup_location, 
          this.state.rate, 
          this.state.delivery_date, 
          this.state.delivery_location, 
          this.state.local, 
          this.state.loaded_miles, 
          this.state.deadhead_miles, 
          this.state.delivery_id, 
          this.state.pickup_zip, 
          this.state.delivery_zip
          )
        this.setState({
            pickup_date: new Date(),
            pickup_zip: '',
            pickup_location: '',
            rate: '',
            delivery_zip: '',
            delivery_date: new Date(),
            delivery_location: '',
            loaded_miles: '',
            deadhead_miles: '',
            local: false,
          delivery_zip: '',
          association_zip: '',
          delivery_id: ''
        })
    }

Вот моя база данных:

ActiveRecord::Schema.define(version: 2019_05_17_163434) do

  # These are extensions that must be enabled in order to support this database
  enable_extension "plpgsql"

  create_table "pickup_deliveries", force: :cascade do |t|
    t.date "pickup_date"
    t.text "pickup_location"
    t.money "rate", scale: 2
    t.date "delivery_date"
    t.text "delivery_location"
    t.boolean "local"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.integer "loaded_miles", default: 0
    t.integer "deadhead_miles", default: 0
    t.integer "delivery_id", default: -> { "nextval('delivery_id_seq'::regclass)" }
    t.text "pickup_zip"
    t.text "delivery_zip"
  end

end

Вот как я устанавливаю функцию приращения для своего вторичного идентификатора:

class AddJobIdSequenceToScores < ActiveRecord::Migration[5.2]
  def up
    execute <<-SQL
      ALTER SEQUENCE delivery_id_seq OWNED BY pickup_deliveries.delivery_id;
      ALTER TABLE pickup_deliveries ALTER COLUMN delivery_id SET DEFAULT nextval('delivery_id_seq');
    SQL
  end

  def down
    execute <<-SQL
      ALTER SEQUENCE delivery_id_seq OWNED BY NONE;
      ALTER TABLE pickup_deliveries ALTER COLUMN delivery_id SET NOT NULL;
    SQL
  end
end

Я в растерянности, и любая помощь очень ценится.
