Tasks Migration

Getting started

Tasks Migration works with Rails 4.1 onwards. Add the following line to your Gemfile

gem "tasks-migration"

Then run

bundle install

Next, you need to run the generator:

rails generate tasks_migration:install

This command will create 2 files:

• db/migrate/<timestamp>_create_tasks_migration_schema.rb (Create new table tasks_migration_schema in database)
• config/tasks_migration.yml (Define Tasks will be runs )

Usage

Basic

Create a new task by command:

rails generate tasks_migration:task <TaskName> [--no-suffix]

Business Logic will be handled in method self.excute on file app/migration_tasks/<task_name>.rb. Example:

# app/migration_tasks/hello_world_task.rb
class HelloWorldTask
  def self.execute
      puts "Hello world :D"
  end
end

And add this task into config/tasks_migration.yml. Example:

# config/tasks_migration.yml
tasks:
  - HelloWorldTask

The last, you run command:

bundle exec rake tasks_migration:migrate

Capistrano

Using Tasks Migration with Capistrano (after deploying completed deploy:finished) we just need to add following line into Capfile:

require "capistrano3/tasks-migration"

Another way, you also can do it manually through Capistrano Task:

bundle exec cap <stage> tasks_migration:migrate
