Question

所以我使用Shopify Gem来访问Shopify API，并注意到在一个简单的ShopifyAPI :: Variant.find调用的响应体中没有返回product_id属性。

1.9.3p194> ShopifyAPI::Variant.find(209901733)
 => #<ShopifyAPI::Variant:0x007fbf7225d3f0 @attributes={"barcode"=>nil, "compare_at_price"=>"198.00", "created_at"=>"2012-03-23T14:11:39+11:00", "fulfillment_service"=>"manual", "grams"=>1000, "id"=>209901733, "inventory_management"=>"shopify", "inventory_policy"=>"deny", "option1"=>"38", "option2"=>"Ivory Mini Twill", "option3"=>nil, "position"=>16, "price"=>"198.00", "requires_shipping"=>true, "sku"=>"3063", "taxable"=>true, "title"=>"38 / Ivory Mini Twill", "updated_at"=>"2013-04-24T10:25:27+10:00", "inventory_quantity"=>2}, @prefix_options={}, @persisted=true>

根据已发布的新文档here，应返回product_id字段。

  }
}

Answer 1

它位于json中，但不存在于从json创建的ActiveResource中。原因是Variant activeresource中的代码：

    self.prefix = "/admin/products/:product_id/"

    def self.prefix(options={})
      options[:product_id].nil? ? "/admin/" : "/admin/products/#{options[:product_id]}/"
    end

如果您愿意，可以创建自己的类来获取单例变体：

      module ShopifyAPI
        class VariantWithProduct < Base
          self.prefix = "/admin/"
          self.element_name = "variant"
          self.collection_name = "variants"
        end
      end

并使用此类通过id：

获取单个变体

    ShopifyAPI::VariantWithProduct.find(xxxxxx)

Answer 2

迈克尔对这个问题的诊断是正确的。对我来说，最简单的方法是获取产品资源而不是变体。 ShopifyAPI::Product ActiveResource对象包含变体。

product = ShopifyAPI::Product.find(product_id)
variant = product.variants.find { |v| v.id == variant_id }

没有使用product_id属性返回Shopify API Variant
