Reference
Used for creating a predefined set of models, similar to db:seed, but will not repopulate if entries already exist.
Place references in ‘db/reference/’ References will be loaded in ascending order, so if an order is desired, prepend 000, 001, 002… etc to the filename.
Run with:
rake reference:load
Example
The below example ensures that there are 6 locations existing in the database after running the ‘rake reference:load’
# db/schema.rb create_table “locations”, :force => true do |t|
t.string "name", :null => false
end
# db/reference/000_locations.rb Location.update_or_create :id => 1, :name => ‘Wellington City’ Location.update_or_create :id => 2, :name => ‘Lower Hutt’ Location.update_or_create :id => 3, :name => ‘Kapiti Coast’ Location.update_or_create :id => 4, :name => ‘Porirua’ Location.update_or_create :id => 5, :name => ‘Upper Hutt’ Location.update_or_create :id => 6, :name => ‘Wairarapa’
