Solidus Product Feed

An extension that provides an RSS feed for products. Google Merchant Feed attributes are also implemented.

Installation

Add solidus_product_feed to your Gemfile:

gem 'solidus_product_feed'

Bundle your dependencies and run the installation generator:

bundle
bundle exec rails g solidus_product_feed:install

You're done! You can now see your RSS feed at /products.rss.

Usage

The feed ships with sensible defaults for your products, but customization is very easy.

Headers

You can easily change the feed's headers by putting the following in your Rails initializer:

SolidusProductFeed.configure do |config|
  config.title = 'My Awesome Store'
  config.link = 'https://www.awesomestore.com'
  config.description = 'Find out about new products on https://www.awesomestore.com first!'
  config.language = 'en-us'
end

Note that you can also pass a Proc for each of these options. The Proc will be passed the view context as its only argument, so that you can use all your helpers:

SolidusProductFeed.configure do |config|
  config.title = -> (view) { view.current_store.name }
  config.link = -> (view) { "http://#{view.current_store.url}" }
  config.description = -> (view) { "Find out about new products on http://#{view.current_store.url} first!" }
  config.language = -> (view) { view.lang_from_store(current_store.language) }
end

Item schema

If you need to alter the XML schema of a product (e.g. to add/remove a tag), you can do it by subclassing Spree::FeedProduct in your app and overriding the schema method:

module AwesomeStore
  class FeedProduct < Spree::FeedProduct
    def schema
      super.merge('g:brand' => 'Awesome Store Inc.')
    end
  end
end

Then set your custom class in an initializer:

SolidusProductFeed.configure do |config|
  config.feed_product_class = 'AwesomeStore::FeedProduct'
end

If you want to change the value of an existing tag, you can also simply override the corresponding tag method (link, price etc.). Check the source code for more details.

Making your feed discoverable

If you want to make your feed discoverable when visiting your store, simply add the following to your storefront's head:

<%= auto_discovery_link_tag(:rss, products_path(format: :rss), title: "My Store's Products") %>

Development

Testing the extension

First bundle your dependencies, then run bin/rake. bin/rake will default to building the dummy app if it does not exist, then it will run specs. The dummy app can be regenerated by using bin/rake extension:test_app.

bundle
bin/rake

To run Rubocop static code analysis run

bundle exec rubocop

When testing your application's integration with this extension you may use its factories. Simply add this require statement to your spec_helper:

require 'solidus_product_feed/factories'

Running the sandbox

To run this extension in a sandboxed Solidus application, you can run bin/sandbox. The path for the sandbox app is ./sandbox and bin/rails will forward any Rails commands to sandbox/bin/rails.

Here's an example:

$ bin/rails server
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
* Listening on tcp://127.0.0.1:3000
Use Ctrl-C to stop

Releasing new versions

Your new extension version can be released using gem-release like this:

bundle exec gem bump -v VERSION --tag --push --remote upstream && gem release
