Django:如何从多对多的字段中获取对象？

class ModelA(models.Model):
    field_name = models.ManyToManyField(ModelB, related_name='related_objects')

model_a = ModelA.objects.get(id=1)
related_objects = model_a.field_name.all()

class IntermediateModel(models.Model):
    model_a = models.ForeignKey(ModelA, on_delete=models.CASCADE)
    model_b = models.ForeignKey(ModelB, on_delete=models.CASCADE)

class ModelA(models.Model):
    field_name = models.ManyToManyField(ModelB, through=IntermediateModel)

class ModelB(models.Model):
    pass

model_a = ModelA.objects.get(id=1)
intermediate_objects = model_a.intermediatemodel_set.all()
related_objects = [obj.model_b for obj in intermediate_objects]
