Non blocking http request

Rails
#1

Any one know if it is possible to do a non-blocking http request
within Ror?

I looked at Net::HTTP, nothing obvious.

In my code, I want to fire off a http request (and not care about the
return or wait for it) and continue with the rest of the work.
I know I can use backgroundrb etc - but that seems an overkill.

Any help appreciated.

thanks.

Seriously, checkout delayed_job. It’s super easy to implement, and is
anything but overkill. Here’s the URL for the project:
http://github.com/collectiveidea/delayed_job

… and as an added bonus, Ryan B. covers it in a Railscast. Here’s
the
URL for the Railscast:

Cheers,
Tim

I agree with Tim on this.

I am working on a new feature in one of my applications that entails
calling a long running process.
I wrote the application to do it synchronously at first to make sure
everything was working.

Then I installed/setup delayed_job, modified my controller to call
@myobject.send_later :my_method and my call was now asynchronous.

Total time to convert from synchronous to asynchronous: < 15 minutes.

Thanks for the info.
delayed_job is a great piece but its just an overkill for what i
wanted.
I wanted something simple - not just from an implementation standpoint

  • but resource too (not add any extra load etc).

“Keep in mind that each worker will check the database at least every
5 seconds.”

For those who are interested, a solution was to use ruby system
(’…&’). I fire it off (and forget) and let the OS mange it. (If
needed, you can also manage the queues via ruby Process)
