Threads in app

[Dmitrii Ermolaev]

code:

threadGetRate = Thread(target=get_from_exch, args=(db, exchg))
threadGetRate.start()

I start app by:

> web2py.py -S 7pay_in -M -R applications/7pay_in/modules/serv_rates.py -A True 60

rise error - for connection to DB

I'm not sure what you are trying to do here, and I don't what error you are saying is happening.

Can you provide more information?

(typically, each request runs in its own thread, and how many threads there are may depend on the front end (Rocket, NginX, Apache, unicorn, etc);  The scheduler also managers a pool of threads).)

It is because pydal-db-connection is thread safe and as you switch to another thread there is no initialized pydal-db-connection in that thread

so you can try db._adapter.reconnect() in your target function (this is that py4web does on every request)
And (as far as I understand) you cannot share uncommitted db-changes between threads as they each have their own db connection
