Package information
Add this line to your application's Gemfile:
gem 'koine-di'
And then execute:
$ bundle
Or install it yourself as:
$ gem install koine-di
dependency_manager = Koine::Di::DependencyContainer.new
dependency_manager.share(:connection) do |dependency_manager|
MyConnection.new("mysql://root@localhost/my_db")
end
dependency_manager.share(:user_repository) do |dependency_manager|
connection = dependency_manager.get(:connection)
UserRepository.new(connection)
end
Also, you can use the singleton instance. Use singleton if you do not have control over how classes, such as controllers, are created.
dependency_manager = Koine::Di.instance
class UsersController < SomeBaseController
def index
@users = repository.find_all
end
private
def repository
dependency_manager.get(:user_repository)
end
end
class DatabaseConnectionFactory < Koine::Di::ServiceFactory
share true
key :db_connection
def create_service(dependencies)
DatabaseConnection.new(dependencies.get(:db_config))
end
end
class UserRepositoryFactory < Koine::Di::ServiceFactory
key :user_repository
def create_service(dependencies)
UserRepository.new(dependencies.get(:db_connection))
end
end
dependency_manager.add_factory(DatabaseConnectionFactory.new)
dependency_manager.add_factory(UserRepositoryFactory.new)
