如何让表django中的一个数据有两个或两个所有者？

from django.db import models
from django.contrib.auth.models import User

class Ownership(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    mymodel = models.ForeignKey(MyModel, on_delete=models.CASCADE)

from django.db import models

class MyModel(models.Model):
    owners = models.ManyToManyField(User, through='Ownership')
    # 其他字段...

from django.contrib.auth.models import User
from .models import MyModel

def create_data(request):
    # 创建MyModel对象
    my_model = MyModel.objects.create()

    # 添加多个所有者
    owner1 = User.objects.get(username='owner1')
    owner2 = User.objects.get(username='owner2')
    my_model.owners.add(owner1, owner2)

    return HttpResponse("Data created successfully.")
