rabbitmq - Celery, route all tasks in a Django project to a specific queue -

-

i have machine runs 2 copies of same django project, let's call them a , b, , want use celery process background tasks.

i set supervisor launch 2 workers, 1 each project, given tasks have same names in both projects, tasks run wrong worker.

my next step use different queue each worker, using -q queuename parameter. using rabbitmqctl list_queues see both queues created. command i'm using issue workers is

python3 -m celery worker -a project -l info -q q1 --hostname=celery1@ubuntu

and

python3 -m celery worker -a project -l info -q q2 --hostname=celery2@ubuntu

the question is, how route tasks project a queue a, , tasks project b queue b? yes, i've seen can add parameter task decorator select queue, i'm looking global setting or that.

edit 1: i've tried using celery_default_queue doesn't work, setting gets ignored. i've tried creating dumb router, this:

class myrouter(object):     def route_for_task(self, task, args=none, kwargs=none):         return 'q1'  celery_routes = (myrouter(), )

and works (obviously return different queues in each project), i'm baffled, why celery_default_queue setting ignored?

at end easier expected. had set both default queue , default routing key (and optionally default exchange, long it's direct exchange).

celery_default_queue = 'q2' celery_default_exchange = 'q2' celery_default_routing_key = 'q2'

i had concepts unclear, after following official rabbitmq's tutorials got clearer , able fix problem.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
