Rails: Run a controller action from code

Question

I would like to automate a task in my Rails app, create a rake task, almost all the code I need is in a controller action, I would like to just call that controller action instead of write the "same" code in my task and save some lines of code. Is that possible?

Well, for example. Say you have usecase to auto renew Stripe customers subscriptions from both Rake tasks and using client side . Now, you will write a PORO class like below:

class AutoRenewSubscription
  attr_reader :coupon, :email

  def initialize args = {}
    @email  = args[:email]
    @coupon = args[:coupon]
    #....
  end

  def run!
    user_current_plan.toggle!(:auto_renew)

    case action
    when :resume
      resume_subscription
    when :cancel
      cancel_subscription
    end
  end
  #... some more code as you need.
end

You can put the class inside app/services/auto_renew_subscription.rb folder. Now this class is available globally. So, call it inside the controller like :

class SubscriptionController < ApplicationController
  def create
   #.. some logic
   AutoRenewSubscription.new(
     coupon: "VXTYRE", email: '[email protected]'
   ).run!
  end
end

And do call it from your rake task also :

desc "This task is to auto renew user subscriptions"
task :auto_renew => :environment do
  puts "auto renew."
  AutoRenewSubscription.new(
    coupon: "VXTYRE", email: '[email protected]'
  ).run!
end

This is what I think good way to solve your issue. Hope you will like my idea. :)
