Overview

A base class which is used for implementing payment methods.

Uses STI (single table inheritance) to store all implemented payment methods in one table (spree_payment_methods).

This class is not meant to be instantiated. Please create instances of concrete payment methods.

Direct Known Subclasses

BillingIntegration, Check, CreditCard, StoreCredit

Defined Under Namespace

Classes: BogusCreditCard, Check, CreditCard, ModelName, SimpleBogusCreditCard, StoreCredit, UnsupportedPaymentMethod

def auto_capture?
  auto_capture.nil? ? Spree::Config[:auto_capture] : auto_capture
end

#gatewayObject

Represents the gateway of this payment method

The gateway is responsible for communicating with the providers API.

It implements methods for:

- authorize
- purchase
- capture
- void
- credit

def gateway
  gateway_options = options
  gateway_options.delete :login if gateway_options.key?(:login) && gateway_options[:login].nil?

  # All environments except production considered to be test
  test_server = gateway_options[:server] != 'production'
  test_mode = gateway_options[:test_mode]

  gateway_options[:test] = (test_server || test_mode)

  @gateway ||= gateway_class.new(gateway_options)
end

#optionsObject

Represents all preferences as a Hash

Each preference is a key holding the value(s) and gets passed to the gateway via gateway_options

Returns:

  • Hash

#partial_nameObject

Used as partial name for your payment method

Currently your payment method needs to provide these partials:

1. app/views/spree/checkout/payment/_{partial_name}.html.erb
The form your customer enters the payment information in during checkout

2. app/views/spree/checkout/existing_payment/_{partial_name}.html.erb
The payment information of your customers reusable sources during checkout

3. app/views/spree/admin/payments/source_forms/_{partial_name}.html.erb
The form an admin enters payment information in when creating orders in the backend

4. app/views/spree/admin/payments/source_views/_{partial_name}.html.erb
The view that represents your payment method on orders in the backend

5. app/views/spree/api/payments/source_views/_{partial_name}.json.jbuilder
The view that represents your payment method on orders through the api

def payment_profiles_supported?
  false
end

#payment_source_classObject

The class that will store payment sources (re)usable with this payment method

Used by Spree::Payment as source (e.g. Spree::CreditCard in the case of a credit card payment method).

Returning nil means the payment method doesn’t support storing sources (e.g. Spree::PaymentMethod::Check)

Raises:

  • (::NotImplementedError)

# File 'app/models/spree/payment_method.rb', line 115

def payment_source_class
  raise ::NotImplementedError, "You must implement payment_source_class method for #{self.class}."
end

#reusable_sources(_order) ⇒ Object

Custom gateways can redefine this method to return reusable sources for an order. See Spree::PaymentMethod::CreditCard#reusable_sources as an example

# File 'app/models/spree/payment_method.rb', line 152

end

#supports?(_source) ⇒ Boolean

Check if given source is supported by this payment method

Please implement validation logic in your payment method implementation

Returns:

  • (Boolean)

#try_void(payment) ⇒ ActiveMerchant::Billing::Response|FalseClass

Used by Spree::Payment#cancel!

Implement ‘try_void` on your payment method implementation to handle void attempts. In that method return a ActiveMerchant::Billing::Response object if the void succeeds. Return false or nil if the void is not possible anymore - because it was already processed by the bank. Solidus will refund the amount of the payment in this case.

This default implementation will void the payment if void succeeds, otherwise it returns false.

Parameters:

Returns:

  • (ActiveMerchant::Billing::Response|FalseClass)
