Seeds

This is a guide to use a custom task for running individual seed files.

Problem

The default seeds.rb file is very useful for Development purposes, it adds a lot of information into our database to get a more 'realistic' experience when we develop. But sometimes a lot of the information we add is common to the production environment too and running the bundle exec rake db:seed command in production is definitely not an option. So for this cases we created a custom rake task that can deal with different seed files.

Example

Say we have an e-commerce app and we want to create a seed file for the categories and subcategories (same info we will use in production).

# db/seeds/categories.rb
Category.transaction do
  Category.create(name: 'Cell phones')
  Category.create(name: 'Computers')
  ...
end

Then you only need to run bundle exec rake db:seed:categories and this will run the categories.rb seed file alone. In order to create the categories in the normal seed you can simply:

# db/seeds.rb
require_relative 'seeds/categories'
