Method: Rack::Payment::Methods#payment

Defined in:

lib/rack-payment/methods.rb

#payment(env_instance_variable = Rack::Payment::DEFAULT_OPTIONS['env_instance_variable']) ⇒ Object

Returns an instance of Helper, which is the main API for working with Rack::Payment

This assumes that this is available via env

If you override the Rack::Payment#env_instance_variable, you will need to pass that string as an option to #rack_payment

# File 'lib/rack-payment/methods.rb', line 17

def payment env_instance_variable = Rack::Payment::DEFAULT_OPTIONS['env_instance_variable']
  rack_payment_instance = rack_payment(env_instance_variable)
  _request_env[ rack_payment_instance.env_helper_variable ] ||= Rack::Payment::Helper.new(rack_payment_instance)
