从命令提示符运行Rails模块

Question

I have a module like this in my Rails application. I have a folder extras inside my app folder. Inside that i have a module.

module ExcelUpload
 class Eupload
   def do_something
   end 
 end

 def self.excel_upload
   upload_service = Eupload.new
   upload_service.do_something 
 end  
end

How to execute this above module from command prompt. I want to execute like rake tasks. Eg - bundle exec rake db:migrate

Is there any command for this?

Answer 1

module name should be the camel casing name of the folder in which you are keeping the .rb file. Here it should be module Extras instead of module ExcelUpload

suggest you to put that module in your \\lib folder of your application's directory structure. From there you can simply access it like Extras::Eupload.excel_upload from your console

Answer 2

You can create a new Rakefile and prepend it with the below, then you can have access to rails from anywhere:

APP_PATH = File.expand_path('../../config/application',  __FILE__)
require File.expand_path('../../config/boot',  __FILE__)
require APP_PATH
# set Rails.env here if desired
Rails.application.require_environment!

Answer 3

create a rake file your_task.rake inside, /lib/tasks

inside this your_task.rake :

namespace :your_task_name do
  desc "Description About your task"
  task :task_name => :environment do
    # Write all your task here
  end

end

now run this task from terminal:

rake your_task_name:task_name

It's simple right. :)
