ନମସ୍କାର，我是Charlie！
在Day22當中我們完成了前端的paypal結帳，而今天我們將完成後端的訂單資料API。

================================◉‿◉=================================

首先是總訂單資料的部分，先在logincheck方法當中新增GET：

@logincheck('POST','GET')

接著在userorder方法當中新增order get的程式碼，把user的order都過濾出來：

if request.method == "GET":
	req = request.GET
	if "username" not in req:
		return R.badRequest("username not found")
	username = req["username"]
	user = User.objects.filter(name = username)
	if not user:
		return R.badRequest("user does not exist")
	user = user[0]
	userorder = Order.objects.filter(user = user)

再來我們要整理一下返回資料的格式，同一個orderno會有一個products的欄位，裡面有這個訂單所有包含的product：

data = []
for order in userorder:
	for d in data:
		if order.orderno == d["orderno"]:
			d["products"].append(order.product.toJson())
			d["amount"] += order.amount
			break
	else:
		data.append({
			"orderno":order.orderno,
			"products":[
				order.product.toJson()
			],
			"username":order.user.name,
			"amount":order.amount,
			"status":order.status,
			"paypal_id":order.paypal_id,
			"created_time":order.created_time,
			"modified_time":order.modified_time
		})
return R.ok({"data":data})

接著做測試，就可以看到同一個訂單內的商品都已經歸到了products裡面：

接著是訂單詳情的部分，首先建立一個url pattern：

url(r'/(?P<orderno>[0-9A-Za-z]{22})$',views.userorder),

接著建立程式碼，過濾出order中符合orderno跟username的Order：

@logincheck('POST','GET')
	if request.method == "GET" and orderno:
		req = request.GET
		if "username" not in req:
			return R.badRequest("username not found")
		username = req["username"]
		user = User.objects.filter(name = username)
		if not user:
			return R.badRequest("user does not exist")
		user = user[0]
		userorder = Order.objects.filter(user = user).filter(orderno = orderno)
		if not userorder:
			return R.badRequest("order does not exist")

		data = {}
		for order in userorder:
			if "orderno" not in data:
				product = order.product.toJson()
				product["amount"] = order.amount
				product["subtotal"] = order.amount * product["price"]
				data = {
					"id":order.id,
					"orderno":order.orderno,
					"products":[
						product
					],
					"username":order.user.name,
					"amount":order.amount,
					"paypal_id":order.paypal_id,
					"created_time":order.created_time,
					"modified_time":order.modified_time,
					"orderStatus":order.status,
					"phone":order.user.phone,
				}
			else:
				product = order.product.toJson()
				product["amount"] = order.amount
				product["subtotal"] = order.amount * product["price"]
				data["products"].append(
					product
				)
				data["amount"] += order.amount
			print(data)
		return R.ok(data)

接著做測試：

就完成了訂單詳情跟總資料的API。

Day23結束了！在今天我們完成了總訂單跟訂單詳情的API，明天我們將完成前端的訂單跟訂單詳情，See ya next day！
