Sample Data

Available rake tasks include:

• rake db:sample_data:load loads all data
• rake db:sample_data:wipe erases all tables
• rake db:sample_data:reload wipes tables and runs :load
• rake db:sample_data:recycle destroys and rebuilds the whole DB then runs :load

To add more sample data tasks, define files in backend/db/sample_data. Each should have a .rake extension and the following structure. If your database table is called 'books' and you have an ActiveRecord model Book, it would look like

backend/db/sample_data/books.rake

namespace :db do
  namespace :sample_data do
    namespace :books do
        task :wipe do
          Book.delete_all
          # plus any other logic necessary for a clean delete
        end

        task :load do
          # any logic necessary to manufacture some random records
          # for this database table
          10.times do
            Book.create( ... values ...)
          end
        end

    task :wipe => 'books:wipe'
    task :load => 'books:load'
  end
end

The last two lines attach db:sample_data:books:wipe and db:sample_data:books:load as dependencies of the overall db:sample_data:load and :wipe tasks.
