Rails How to execute task in seed

Here’s how I executed task in seeds.rb, in Rails.

The Rails 4 Way


  • Ruby 2.2.2p95
  • Rails 4.1.8
  • Rake 10.4.2

First, create a task with rails g task sample shot. The following code will be generated.

Now, we can execute the task with bundle exec rake sample:shot. The goal is to execute the task when bundle exec rake db:seed is executed. Maybe, it is the same way to execute task in rails code.


Add the code into seeds.rb, like below.

Environment (test, development, production) is passed, which is valid in rake db:seed. On the above, set 'value' to SOMETHING. It is like FEATURES in rake db:fixture:load FIXTURES=xxxx.
