robertriver / shopify_hooks

some hooks engine like

ShopifyHooks

Installation

Add this line to your application's Gemfile:

gem 'shopify_hooks'

And then execute:

$ bundle

Usage

Add something like this or better checks to get a token and set your shop in application.rb. There is a better way.

config.after_initialize do
  begin
    ShopifyAPI::Base.site = ShopifyHooks.shopify_url
    ShopifyAPI::Shop.current
  rescue StandardError => error
    puts error
  end
end

Create a initializers/shopify_hooks.rb file

ShopifyHooks.configuration do |config|
  config.shopify_base_url = "https://little-store-of-testing.myshopify.com/"
  
  config.shopify_url = "https://#{ENV["shopify_api_key"]}:#{ENV["shopify_api_password"]}@little-store-of-testing.myshopify.com/admin"
  
  config.shopify_webhook_route = "https://00c6cc41.ngrok.io/api/shopify_hooks/"
  
  config.default_vendor = 'Mathews'
  
  config.shopify_shared_secret =  ENV['shopify_shared_secret']
  
  config.shopify_multipass_secret = ENV['shopify_multipass_secret']
  
  config.given_app_proc = Powertex.create_order_from_shopify
  
end   

Mount it in routes.rb

mount ShopifyHooks::Engine => '/api'

Include in a model

ie:

include ShopifyHooks::Shopifyable	

Shopifyable things

Including Shopifyable in a class will add afte_save and after_destroy callbacks to call the shopify API and do things.

Look at the sorce code in lib/shopify_hooks/shopifyable for more info

Other Methods

Accessing config variables

ShopifyHooks::shopify_base_url returns => "https://little-store-of-testing.myshopify.com/"

Multipass Login

token = ShopifyHooks::ShopifyMultipass.new(ShopifyHooks.shopify_multipass_secret).generate_token({email:current_user.email})	

redirect_to(ShopifyHooks::shopify_base_url + "account/login/multipass/#{token}")

Workers and Controllers

This engine adds callback routes at

whereveryoumountit/ 

ShopifyHooks::Engine.routes.draw do
	scope '/shopify_hooks' do
    	scope 'products' do
			post '/create' => 'shopify_hooks/shopify_hooks#create_product'
	      	post '/update' => 'shopify_hooks/shopify_hooks#update_product'
    	end
    scope 'orders' do
	  post '/create' => 'shopify_hooks/shopify_hooks#create_order'
      post '/update' => 'shopify_hooks/shopify_hooks#update_order'
	end
  end
end

• So a post to whereveryoumountit/shopify_hooks/products/create will call create_product in the shopify_hooks_controller defined in this engine
• The Controllers are at app/controllers

There are also workers created for creating orders and and keeping products up to date.

look in app/workers/* source code for more info.

This line in the shopify_hooks.rb initializer is how we tell shopify what to do after we create an order from shopify and it calls it's worker. This needs to be defined somewhere in the home app.

config.given_app_proc = Powertex.create_order_from_shopify

ie lib/modules/powertex.rb

class Powertex

  PowertexApi::Api.initiate_connection(
	  api_key:  ENV['powertex_api_key'],
      username: ENV['powertex_username'],
	  password: ENV['powertex_password']
  )

  def self.create_order_from_shopify
	return Proc.new do |args|
		# Do something with args from order worker 
	  end
  end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
