Save many metafields with a single request

There does not seem to be a way to attach metafields locally, and then simply save the product with the metafields along with it. I'm forced to use add_metafields() or Metafield().save(), both of which adds a single metafield per API call. This is very slow.

If I take a product with 50 metafields, and save it as a new product, it saves almost instantly, like so:

p = shopify.Product.find()[0]
print len(p.metafields())
> 50
p.id = None
p.images = None
p.save()

How can I attach metafields to a product in the same way they are attached when they are fetched?

首先追蹤 Product.save()、add_metafields() 和 Metafield().save()，以了解擷取的 metafields 如何表示及持久化。當本機附加的 metafields 能夠與新 product 一起透過單一 API 請求儲存，並涵蓋回報的多個 metafields 案例時，工作即告完成。
