django 模型对象实例应该传递给 celery 吗

使用Django和Celery进行异步任务处理是一个常见的场景。在这种情况下，我们可能会遇到一个问题：是否应该将Django模型对象实例直接传递给Celery任务？

pip install django
pip install celery

python
# settings.py
# Celery配置
CELERY_BROKER_URL = 'amqp://localhost'  # 消息队列的URL
CELERY_RESULT_BACKEND = 'rpc://localhost'  # 结果后端的URL
# Django应用配置
INSTALLED_APPS = [
    ...
    'django_celery_results',
]

python
# tasks.py
from celery import shared_task
from .models import MyModel
@shared_task
def process_model_instance(model_id):
    try:
        model_instance = MyModel.objects.get(id=model_id)
        # 在这里处理模型对象实例
        ...
    except MyModel.DoesNotExist:
        pass

python
# views.py
from .tasks import process_model_instance
def my_view(request):
    # 获取模型对象实例的主键
    model_id = 1
    # 调用Celery任务
    process_model_instance.delay(model_id)
    return HttpResponse('任务已触发')
