这是一个电子商务用例,我需要消耗一天内的所有订单,生成单个订单标题,并列出订单项的汇总摘要。这意味着我需要根据共享值 (sku) 对订单项对象数组进行重复数据删除。我还需要根据相同的值对某些字段(数量、总购买价格)求和。
示例输入:
{
"Account": {
"Account Name": "Firefly",
"Order": [
{
"OrderID": "order103",
"Product": [
{
"Product Name": "Bowler Hat",
"ProductID": 858383,
"SKU": "0406654608",
"Description": {
"Colour": "Purple",
"Width": 300,
"Height": 200,
"Depth": 210,
"Weight": 0.75
},
"Price": 50.0,
"Quantity": 2
},
{
"Product Name": "Trilby hat",
"ProductID": 858236,
"SKU": "0406634348",
"Description": {
"Colour": "Orange",
"Width": 300,
"Height": 200,
"Depth": 210,
"Weight": 0.6
},
"Price": 21.67,
"Quantity": 1
}
]
},
{
"OrderID": "order104",
"Product": [
{
"Product Name": "Bowler Hat",
"ProductID": 858383,
"SKU": "040657863",
"Description": {
"Colour": "Purple",
"Width": 300,
"Height": 200,
"Depth": 210,
"Weight": 0.75
},
"Price": 100,
"Quantity": 4
},
{
"ProductID": 345664,
"SKU": "0406654603",
"Product Name": "Cloak",
"Description": {
"Colour": "Black",
"Width": 30,
"Height": 20,
"Depth": 210,
"Weight": 2
},
"Price": 107.99,
"Quantity": 1
}
]
}
]
}
}
期望的输出:
{
"header": "Some Header Fields...",
"line items": [
{
"Product Name": "Bowler Hat",
"ProductID": 858383,
"SKU": "0406654608",
"Description": {
"Colour": "Purple",
"Width": 300,
"Height": 200,
"Depth": 210,
"Weight": 0.75
},
"Price": 150,
"Quantity": 6
},
{
"Product Name": "Trilby hat",
"ProductID": 858236,
"SKU": "0406634348",
"Description": {
"Colour": "Orange",
"Width": 300,
"Height": 200,
"Depth": 210,
"Weight": 0.6
},
"Price": 21.67,
"Quantity": 1
},
{
"ProductID": 345664,
"SKU": "0406654603",
"Product Name": "Cloak",
"Description": {
"Colour": "Black",
"Width": 30,
"Height": 20,
"Depth": 210,
"Weight": 2
},
"Price": 107.99,
"Quantity": 1
}
]
}
我知道我可以使用 $distinct() 获得一组 skus,但我不知道如何生成完全不同的对象并保留其值。
我认为我不能应用合并,因为对象的某些部分(数量)不是唯一的,而且我不知道如何仅在对象本身的某些字段上进行合并。
最后,我在一个没有代码片段的平台上工作,所以我不能调用 javascript。这在纯 JSONata 中可能吗?
