如何在Django中向现有模型添加数据？

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
    email = models.EmailField()

from django.contrib import admin
from .models import Person

admin.site.register(Person)

python manage.py makemigrations
python manage.py migrate

from myapp.models import Person

# 创建一个新的Person对象
person = Person(name='John Doe', age=30, email='john.doe@example.com')

# 将对象保存到数据库中
person.save()

from myapp.models import Person

# 创建一个Person对象列表
people = [
    Person(name='Jane Doe', age=28, email='jane.doe@example.com'),
    Person(name='Bob Smith', age=35, email='bob.smith@example.com'),
]

# 将对象列表批量保存到数据库中
Person.objects.bulk_create(people)
