ServiceFactory
IOC container
Installation
Add this line to your application's Gemfile:
gem 'service_factory'
And then execute:
$ bundle
Or install it yourself as:
$ gem install service_factory
Usage
- Create service_factory.rb in config/initializers directory
ServiceFactory.register do
user_info UserInfo
remote_data_service do |url|
RemoteData.new(url)
end
env :test, :development do
user_info Fake::UserInfo
end
memoize do
memoized_info { costly_operation }
memoized_class BigFatClass
end
end- Then you can use it
ServiceFactory.user_info("John Dou") #Same as UserInfo.new("John Dou") or Fake::UserInfo.new("John Dou")
ServiceFactory.remote_data_service("http://service.com") #Same as RemoteData.new("http://service.com")
ServiceFactory.memoized_info #Runs only onceSee spec/service_factory_spec.rb for the full list of features
- You can also use rspec-mock with this factory
ServiceFactory.should_receive(:user_info).with("John Dou").and_return(double(:user_info, address: "baker street"))- Sometimes runing rails in development (for example, using
rails s) lead to empty factory after reloading. To prevent this add code to config/environment/development.rb
ActionDispatch::Reloader.to_prepare do
load Rails.root.join('config/initializers/implementation.rb')
