如何在金字塔中使用pyramid_celery？

Question

I want to use celery with pyramid. Try to use pyramid_celery package. Аll attempts have failed.

My development.ini has:

BROKER_URL = amqp://dev:dev@192.168.1.50:5672//test
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_ACCEPT_CONTENT = ['json', 'application/json']
CELERY_RESULT_BACKEND = amqp://dev:dev@192.168.1.50:5672//test
;CELERY_ACCEPT_CONTENT = json12
CELERY_IMPORTS = celerypythontest.celery_service

And when i try to run this command:

celery worker -A pyramid_celery.celery_app --ini development.ini

i have this output:

H:\\Development\\CeleryPythonTest>celery worker -A pyramid_celery.celery_app --ini development.ini

And every time, when i try to run celery, the output error is different:

_pickle.PicklingError: Can't pickle <InterfaceClass pyramid.request.__static/_IRequest>: attribute lookup __static/_IRequest on pyramid.request failed


_pickle.PicklingError: Can't pickle <function _compile_route.<locals>.matcher at 0x0000000004BB0620>: attribute lookup _compile_route.<locals>.matcher on pyramid.urldispatch failed

_pickle.PicklingError: Can't pickle <function beforerender_subscriber at 0x0000000003CD8D90>: it's not the same object as pyramid_debugtoolbar.toolbar.beforerender_subscriber

Can anyone tell me, what i am doing wrong?

Thanks!

Run under Linux. And all problems gone!

• Don't use celery on windows!
• Don't develop on python under windows!

This is log from celery starting
