Spree Split Payments

######THIS GEM IS NOT READY FOR PRODUCTION USE.

This extension provides the feature for a spree store to allow user to club payment methods to pay for the order.

Easily configurable from the admin end where one can select which payment methods should be allowed for clubbing and their priorities which can be used while creating payments and displaying them to the user.

Installation

Add spree-split-payments to your Gemfile:

gem 'spree-split-payments'

Bundle your dependencies and run the installation generator:

bundle
bundle exec rails g spree_split_payments:install

Integration

The extension needs a way to find out the maximum amount that can be made via a payment method. To do so it sends a message to the user object as:

#{payment_method.class.name.demodulize.underscore}_for_partial_payments

# for example : for Spree::PaymentMethod::LoyaltyPoints it calls for
# loyalty_points_for_partial_payments
# on current_user

So you can either

Alias an exising method like

# models/spree/user_decorator.rb
alias_method :loyalty_points_for_partial_payments, :loyalty_points_equivalent_currency

# where loyalty_points_equivalent_currency is the method provided by
# Spree::PaymentMethod::LoyaltyPoints extension.

Define a method under user class. For example for Spree::PaymentMethod::LoyaltyPoints)

#models/spree/user_decorator.rb
Spree::User.class_eval do
  ...

  def loyalty_points_for_partial_payments
    # logic goes here
  end

  ...

end
