Django-RQ 很难将项目添加到 Django 模型

编程问答 2022-05-12

问题描述

我正在使用 django-rq 来设置使用 Redis 的后台任务。 Redis 运行良好，代码正在向 Redis 发送请求 - 但它引发了异常。

Exception:
Traceback (most recent call last):
  File "/Users/jeremyenglert/Documents/Sites/showzone/.venv/lib/python3.8/site-packages/rq/worker.py",line 1003,in perform_job

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS,but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings

这是代码的简化版本。

# views.py
class PlayerProfileView(viewsets.ModelViewSet):
    ...

    def get_queryset(self):
        ...

    @action(methods=['get'],detail=False)
    def update_all_profiles(self,request,pk=None):
        update_player_profiles.delay(PlayerProfile)

        return Response(status=status.HTTP_200_OK)

# update_player_profiles.py
@job
def update_player_profiles(model):
    a_long_running_request_for_a_csv_file()
    a_long_running_task_to_process_data()
    a_long_running_task_to_save_the_data_to_a_django_model()

如何让 django-rq 与 django 模型交互？还是有不同的问题在起作用？
