Usage¶ ↑

Put your YAML based seeds into db/seeds/model_table_name.yml

For a Country model with attributes name and population, 
the seed file (db/seeds/countries.yml) content would be:

country_1:
  name: Australia
  population: 1233344

For belongs_to relationships, you can reference the relationship with the seed name.
If a City belongs to a country then:
  city_1:
    name: Melbourne
    country: country_1

You can also write ruby code inside the YAML seed files:
  city_1:
    name: Melbourne
    country: country_1
    founded_in: <%= 30.years.ago.to_s(:db) %>

In the db/seeds.rb file

SeedLoader::Loader.seed_files_to_db

Run the seeds rake task

rake db:seed
