使用shopify_api gem的shopify订单履行问题

Question

I have a problem in fulfilling the line item in a order through shopify_api gem. When I fulfill a single line item it fulfills all the line items in the order. I have looked into it and people say something about setting headers, please clearify.

What I am doing is

order = ShopifyAPI::Order.find(order_id)

Suppose this order has multiple line items

f = ShopifyAPI::Fulfillment.new(:params => { :order_id => order.id, :line_items => [ {"id" => order.line_items.first.id} ] })

f.prefix_options = { :order_id => order.id }

f.save

This piece of code fulfills all the line items in the order and set the fulfillment status as fulfilled which was not desired.

Below are the details with header, fulfillment object and tcpdump:

Shopify headers

(rdb:1) p ShopifyAPI::Fulfillment.headers
{"User-Agent"=>"ShopifyAPI/3.0.1 ActiveResource/3.1.1 Ruby/1.9.2", "X-Shopify-Access-Token"=>"be9d4adaa35e7f82b720a3567250424c"}

Fulfillment object

#<ShopifyAPI::Fulfillment:0xca2086c @attributes={"params"=>#<ShopifyAPI::Fulfillment::Params:0xca20b00 @attributes={"order_id"=>138494648, "notify_customer"=>true, "tracking_number"=>"12345678", "line_items"=>[#<ShopifyAPI::LineItem:0xca28904 @attributes={"id"=>225568082}, @prefix_options={}, @persisted=false>]}, @prefix_options={}, @persisted=false>}, @prefix_options={:order_id=>138494648}, @persisted=false>

tcpdump output

Answer 1

The actual problem is that when you're creating the fulfillment you're passing :params => hash_of_fulfillment_data to the new method. Just pass the data, you don't need a params key. This is just standard ActiveResource, nothing special. This should work:

f = ShopifyAPI::Fulfillment.new(:order_id => order.id, :line_items =>[ {"id" => order.line_items.first.id} ] )
f.prefix_options = { :order_id => order.id }
f.save
