如何保存在ready方法中创建的数据？Django产品与测试数据库

from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)

from django.apps import AppConfig
from .models import Product

class MyAppConfig(AppConfig):
    name = 'myapp'

    def ready(self):
        # 创建并保存一些初始产品数据
        products = [
            Product(name='Laptop', price=999.99),
            Product(name='Smartphone', price=499.99),
            Product(name='Tablet', price=299.99),
        ]
        Product.objects.bulk_create(products)

INSTALLED_APPS = [
    ...
    'myapp.apps.MyAppConfig',
    ...
]

python manage.py test

from django.apps import AppConfig
from .models import Product

class MyAppConfig(AppConfig):
    name = 'myapp'

    def ready(self):
        if not Product.objects.exists():
            products = [
                Product(name='Laptop', price=999.99),
                Product(name='Smartphone', price=499.99),
                Product(name='Tablet', price=299.99),
            ]
            Product.objects.bulk_create(products)
