Importing records into custom engine via CSV?

[ni...@tinygoatstudio.com]

Hi all:

I've built a custom "products" engine. I'd like to import a long list of products via a CSV file, but I frankly have no idea how. This seems fairly straightforward in plain vanilla Rails, but it just isn't working at all inside my custom engine. I've built the following rake task to handle the import:

require 'csv'

namespace :refinery do

  namespace :products do

    # call this task by running: rake refinery:products:import_csv

    desc "Import products via CSV"

    task :import_csv => :environment do

      CSV.foreach('db/product.refinery_products.csv') do |row|

        puts "Counting headers in CSV file..."

        product_id              = row[0]

        model_number            = row[1]

        category                = row[2]

        subcategory             = row[3]

        description             = row[4]

        meta_heading            = row[5]

        logo                    = row[6]

        lo_res_image            = row[7]

        hi_res_image            = row[8]

        main_description        = row[9]

        feature_indications     = row[10]

        certification           = row[11]

        puts "Adding products to database..."

        Refinery::Products.create(

          product_id: product_id, 

          model_number: model_number, 

          category: category, 

          subcategory: subcategory, 

          description: description,

          meta_heading: meta_heading,

          logo: logo,

          lo_res_image: lo_res_image,

          hi_res_image: hi_res_image,

          main_description: main_description,

          feature_indications: feature_indications,

          certification: certification

        )

        puts "Finished"

      end

    end

  end

end

When I run it, I get the error "undefined method `create!' for Refinery::Products:Module". So, what methods do I have access to in the models that are created when I make a custom engine—and how can I make this work?

Thanks all!

Instead of Refinery::Products.create you want to use Refinery::Products::Product.create otherwise you're calling create on the Products namespace and not on the Product model. :)
