Instance Method Details

#_request_env ⇒ Object

This method returns the Rack ‘env’ for the current request.

This looks for #env or #request.env by default. If these don’t return something, then we raise an exception and you should override this method so it returns the Rack env that we need.

  if respond_to?(:env)

  end
end

#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
