针对特定环境调用耙任务

Question

Hello I'm writing a deploy script(rake task) for my mini project. And I have this part when I invoke the db seed :

Rake::Task['db:seed'].invoke

And also compiling assets :

Rake::Task['assets:precompile'].invoke

So I was wondering is there a way to invoke these tasks in production environment like you would do from a console like this :

RAILS_ENV=production rake db:seed

Answer 1

In Rails, you can do as :

[arup@app (master)]$ rails g task my_namespace my_task1
      create  lib/tasks/my_namespace.rake
[arup@app (master)]$ cat lib/tasks/my_namespace.rake
namespace :my_namespace do
  desc "TODO"
  task my_task1: :environment do
  end
end
[arup@app (master)]$

Now see the Rakefile is ready for you.

Just open the Rakefile you just created, and define your tasks.

namespace :my_namespace do
  task my_task1: :environment do
    Rake::Task['db:seed'].invoke
    Rake::Task['assets:precompile'].invoke
  end
end
