#pyramid

hey hey, I'm processing something that has limited grace time by the requestor so I need to just tell it leave the request with me and return ok while I go and handle it for however long it takes. I found pyramid-scheduler it looks more attactive than RQ which has dependency for redis

can anyone please recommend a lib to use for scheduling?

or what is defacto lib for scheduling used in pyramid world?

tomas have you looked at the list on trypyramid.com?

you can filter by "Task Queueing", assuming that is what you mean by "scheduling"

stevepie_: I haven't but thanks

will do

stevepie_: both pyramid_celery

and pyramid_rq

require extra bits

tomas maybe someone else knows. i don't do that kind of stuff yet

nps stevepie_ thanks for your help (;

tomas: You can look at using async stuff that would allow you to keep things running in the background and return early, however more generally you'll want something that allows you to queue the work to be done and fetch results at a later time.

tomas: Celery and RQ are both good targets for things like that.

x58: it looked like https://apscheduler.readthedocs.io/en/latest/us... was good too (it allows to init with MemoryJobStore)

it's used by pyramid-scheduler

That'll run them as threads within your existing processes.

I'm generally not a big fan, since it ties the lifetime of your queue/workers to the lifetime of your HTTP server, but it'll work.

thanks x58 I'll keep that in mind

hi, new to pyramid here. setup a project using the sqlalchemy cookiecutter. i'd like to make the default permission for the entire application to be DENY_ALL. so i passed a default_permission=DENY_ALL to the configurator but get this in return when i run pserve - TypeError: unhashable type: 'AllPermissionsList'. what do i need to do before setting that?

rajesh: deny_all is not actually a permission, it's an access control entry (a 3-tuple) shorthand for (Deny, Everyone, ALL_PERMISSIONS)

what you actually should do is just define a config.set_default_permission('deny') ... some dummy permission that you'll never assign to a user

or one that you would, it doesn't really matter

if the user doesn't have that permission then they will be denied

the manual says: " permission should be a permission string to be used as the default permission"

so if DENY_ALL isn't a string, that won't work

and raydeo said what you need to do instead :-)

raydeo: betabug : thanks. i assumed DENY_ALL, being a 'special' ACE, was going to be applied across.

rajesh: the docs are really good, careful reading is always recommended

betabug: yes, i should have continued reading instead of assuming. :)

:-)

the first summer I worked with pyramid, I took a pdf of the documentation along, and worked most of the summer offline, only with that... it worked exceptionally well

that approach has worked well for me before too. particularly the 'offline' part.
