Rake task vs script/runner

Hello, until now I allways used script/runner for running Rails cron jobs

I wonder is there is any benefit (except not having any fake runner model in the models directory) to use a rake task instead in lib/tasks

Thanks

Hi,

I also want to use the script/runner to run the Rails cron jobs. But I don't know how to do that. So can you please share the code here so that i will get some ideas?

Thanks in advance...

It's very simple, all you have to do is create a new model in app/models, eg. runner.rb

class Runner def self.doIt() end end

Then, launch it from the command line script/runner Runner.doIt or a cron task ruby /somedir/script/runner Runner.doIt

The difference between them is that script/runner boots Rails whereas a Rake task doesn't unless you tell it to by making the task depend on :environment, like this:

task :some_useful_task => :environment do   # do some useful task end

Since booting Rails is expensive, it might be worth skipping if you can avoid it.

Other than that, they are roughly equivalent.
