SpreeImporterCore

Spree Importer engine. Adds an easy way to massively load different Spree models, the way you need it.

Installation

spree_importer_core supports:

  • Ruby 2.1+
  • Rails 4.2+
  • Spree 3.0+

Add spree_importer_core to your Gemfile

gem 'spree_importer_core'

bundle install your dependencies and run the installation generator:

bundle install
bundle exec rails g spree:importer_core:install

Note: SpreeImporterCore uses ActiveJob for background processing. You may want to specify an adapter before importing, otherwise the job is immediately executed.

Usage

You can generate an importer file running

rails g spree:importer_core:importer Thing

This will generate the needed files in order to make the importer to work as intended.

  • Create new importer file
  • Insert importer locales for new importer class
  • Add sample importer template
  • And, update importers list

Then, just restart your rails server

New importer Class

The new importer class will be placed at lib/spree_importer_core/thing_importer.rb

Importer behavior must be defined in order to correctly import spreadsheet rows. e.g: Updating stock

class Spree::ThingImporter < Spree::ImporterCore::BaseImporter
  # Load a file and the get data from each file row
  def load_data(row:)
    sku = row[0]
    stock = row[1]
    if variant = Spree::Variant.find_by(sku: sku)
   	  stock_item = Spree::StockItem.find_by variant_id: variant.id
      stock_item.update_attribute(:count_on_hand, stock)
    end
  end
end

Note: you can give the importer any name you want, thou it is highly recommended to give one that describes its content

Locales

Locales will be placed at config/spree_importer_core.en.yml

en:
  spree:
    spree_importer_core:
      importers:
        thing:
          title: Thing Importer
          name: Thing

Every importer needs title for views and name for the menu

Add sample importer template

ImporterCore create a sample importer template at lib/spree_importer_core/templates/, you need to replace with their correct content. In the last example, file be called thing.xlsx.

Importer List

ImporterCore defines a list with the available importers, you may want to add or remove your own importers. Remember to make your classes to inherit from Spree::ImporterCore::BaseImporter, otherwise needed methods won't be defined.

Edit config/initializers/spree.rb to define/modify the available importers.

Spree::ImporterCore::Config.importers << Spree::ThingImporter

Testing

First bundle your dependencies, then run rake. rake will build the dummy app if it does not exist, then it will run specs. The dummy app can be regenerated by running rake test_app.

bundle
bundle exec rake

When testing your application you will want to use its factories. Simply add this require statement to your spec_helper:

require 'spree/importer_core/factories'
