[SOLVED] How to add a product variant with the Ruby gem

How to add a product variant with the Ruby gem

What is the correct way to add a product variant?

I create the product successfully and it shows up in my Shopify admin. However the price is always zero and the quantity is always infinity.

I've tried creating a variant with inventory_quantity and price set, as well as with product_id set in prefix_options.

However admin is always showing price zero and quantity infinity.

Rails v3.2.5
shopify_api v3.0.0
shop name: vacation-2

I don't get errors doing the API calls. I simply don't see my variant data in the product in admin.

Solution

Make sure that you set the :inventory_management attribute to "shopify", or the quantity won't persist.

I just tested this out, and it works perfectly:

product.variants << ShopifyAPI::Variant.new(
  :option1              => "Large",
  :price                => 12.95,
  :inventory_management => 'shopify',
  :inventory_quantity   => 10
)
product.save
