Django:如何在bulk_create之前检查重复项(在定义对象时)？

from myapp.models import MyModel

# 假设我们有一个模型MyModel，它有一个唯一的字段'name'
names_to_create = ['name1', 'name2', 'name3']
existing_names = MyModel.objects.filter(name__in=names_to_create).values_list('name', flat=True)

# 过滤掉已经存在的名字
names_to_create = [name for name in names_to_create if name not in existing_names]

# 创建对象
objects_to_create = [MyModel(name=name) for name in names_to_create]
MyModel.objects.bulk_create(objects_to_create)

from myapp.models import MyModel

names_to_create = ['name1', 'name2', 'name3']
objects_to_create = []

for name in names_to_create:
    obj, created = MyModel.objects.get_or_create(name=name)
    if created:
        objects_to_create.append(obj)

# 批量创建对象
MyModel.objects.bulk_create(objects_to_create)
