编辑 YOUR_ENGINE/lib/tasks/YOUR_ENGINE_tasks.rake
namespace :db do
namespace :YOUR_ENGINE do
desc "loads all seeds in db/seeds.rb"
task :seeds => :environment do
YOUR_ENGINE::Engine.load_seed
end
namespace :seed do
Dir[Rails.root.join('YOUR_ENGINE', 'db', 'seeds', '*.rb')].each do |filename|
task_name = File.basename(filename, '.rb')
desc "Seed " task_name ", based on the file with the same name in `db/seeds/*.rb`"
task task_name.to_sym => :environment do
load(filename) if File.exist?(filename)
end
end
end
end
end
然后在您的主应用程序中,您可以执行自定义种子命令,单独执行任何种子文件
$rake -T | grep YOUR_ENGINE
rake db:YOUR_ENGINE:seed:seed1 # Seed seed1, based on the file with the same name in `db/seeds/*.rb`
rake db:YOUR_ENGINE:seeds # loads all seeds in db/seeds.rb
