This is quick implementation for passing payments through Paysto gateway. It works only with «onlineMerchant». Your PRs are welcome.

Check demo shop in action: ror.paysto.in. And source code here.

Add this line to your application's Gemfile:

gem 'paysto-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paysto-rails

After installation run this command:

rails generate paysto:install

It will create files for you:

  create  config/initializers/paysto.rb
  create  config/locales/paysto.en.yml
  create  config/locales/paysto.ru.yml
  create  app/controllers/paysto_controller.rb

and extend your routes with:

  namespace :paysto do
    post :success, :fail, :check, :callback
    get  :fail
  end

Right now you may configure model names in config/initializers/paysto.rb file for payments, invoices and their notifications. By default they are Payment, Invoice and InvoiceNotification respectively.

Then run this command:

rails generate paysto:models

It will create your models and migration:

  create  db/migrate/20140101000000_create_paysto_tables.rb
  create  app/models/payment.rb
  create  app/models/invoice.rb
  create  app/models/invoice_notification.rb

In the simple case only what you should to do:

1. Put your real credentials in config/initializers/paysto.rb as well
2. Run rake db:migrate

That's all.

You have 3 models and 1 controller now if you did everything right before. Check models and extend them with logic or associations, which you need in your application.

Controller by default extended with concern and contains all necessary methods:

class PaystoController < ApplicationController
  include Paysto::Controller
end

But you may override methods as you want. For example, if you want to redirect user to custom URL when payment is passed:

class PaystoController < ApplicationController
  include Paysto::Controller

  def success
    flash[:success] = I18n.t('paysto.success')
    redirect_to any_custom_payments_path
  end
end

Also you can customize check or callback methods using Paysto module as you want, but do it only if you know what's going on there.
