Running a Rails controller method from shell?

In a controller for a rails project I have, there is a helper function that sends an e-mail containing all the changes to the database done in the past week. I also have a cron job on Unix that runs a number of bash scripts every weekend related to my web application. Is there an easy method to run a controller's helper function from a standalone .rb file or bash script?

If you're actually wanting to make the web request from within your crontab, you can just call wget or curl on the target URL.

0 * * * * wget http://yourdomain.com/path/to/request -o /dev/null

If you're wanting to execute this mailer outside the context of a web request, this sort of behavior should not be in your controller. This is what lib/ is for.

You can create a file like lib/my_helpers.rb containing

module MyHelpers
  extend self

  def your_mailer(some, params, here)
    # runthe mailer
  end
end

You can include this in whatever controller you want, or even ApplicationController

include ::MyHelpers

Wherever it is included, you can then simply call your_mailer(param1, param2, param3) to execute it.

You would then include this from within a rake task, and execute the rake task from your crontab. Create a file in lib/tasks/your_mailer.rake with something like this

include MyHelpers

namespace :myapp do
  desc "Runs your_mailer"
    task :mailer => :environment do
    your_mailer(param1, param2, param3)
  end
end
