Threading in Rails

Rails
1

Hello,

I was wondering if someone can point me how to invoke threads from an
action
in a controller. Basically, in an action, I want to do some tasks
asynchronously for which user need not wait.

It isn’t safe (at least not now) to create threads in Rails, but you
can use something like Background Job →

Does this background job maintains a queue sort of thing? If yes, then
how
does some tasks can be concurrently executed?

Check out the last two Railscasts.

I think this might be what you need.

Background job usually runs a job at a time, which is cool as Ruby
itself is almost “single threaded”, but if you want a solution with
concurrent job execution, you can try SkyNet →

I installed skynet in my rails application using
$skynet_install --rails .

After this, when I try to start my server (Mongreal), it throws me
following
error.

=> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on http://127.0.0.1:3005
=> Call with -d to detach
=> Ctrl-C to shutdown server
