has_integrations

Rails gem for a pattern to manage 3rd party service integrations

gem 'has_integrations'

or

gem install has_integrations

Once the gem is installed, in your app, run

rails generate has_integrations:install

Which will set up the Integration Model and a migration for the Integration model.

class User < ApplicationRecord
  # ...

  has_many :integrations,
    dependent: :destroy, extend: HasIntegrations,
    as: :owner

  # ...
end

# Get Stripe Integration.
stripe_integration = user.integrations[:stripe]

# Set Stripe Integration.
# This will create and save a new integration
# if there wasn't already a stripe integration record.
user.integrations[:stripe] = { "livemode" => false, "stripe_user_id" => 1 }

# Get the stored config.
user.integrations[:stripe].config
# => { "livemode" => false, "stripe_user_id" => 1 }

# Check if an Integration exists.
user.integrations.has?(:stripe)
# => true or false

This gem assumes each owning object can only have one type of each integration.

In config/initializers/has_integrations.rb:

HasIntegrations.encryption_key = 'my great key'

Used for attr_encrypted on the config column

With the built in Integration class, you can monkey patch to add validations / whatever other logic.

• Allow the generate to be passed an existing Integration class. This may be a weird config option, because the Integration class needs kind, encrypted_config, owner_id, and owner_type -- would all these columns need to be configurable?
