如何在django模型中将两个相关模型连接在一起，这样我就可以从这两个模型中提取所有数据？

from django.db import models

class ModelA(models.Model):
    # 定义Model A的字段
    field1 = models.CharField(max_length=100)
    # ...

    def __str__(self):
        return self.field1

from django.db import models

class ModelB(models.Model):
    # 定义Model B的字段
    field2 = models.CharField(max_length=100)
    model_a = models.ForeignKey(ModelA, on_delete=models.CASCADE)
    # ...

    def __str__(self):
        return self.field2

python manage.py makemigrations
python manage.py migrate

model_a_data = ModelA.objects.all()

model_b_data = ModelB.objects.filter(model_a=model_a_instance)
