问题是用json对象的嵌套数组规范化json。我也看过类似的问题,并试图用他们的解决办法,但没有效果。在
这就是我的json对象的样子。在
{
"results": [
{
"_id": "25",
"Product": {
"Description": "3 YEAR",
"TypeLevel1": "INTEREST",
"TypeLevel2": "LONG"
},
"Settlement": {},
"Xref": {
"SCSP": "96"
},
"ProductSMCP": [
{
"SMCP": "01"
}
]
},
{
"_id": "26",
"Product": {
"Description": "10 YEAR",
"TypeLevel1": "INTEREST",
"Currency": "USD",
"Operational": true,
"TypeLevel2": "LONG"
},
"Settlement": {},
"Xref": {
"BBT": "CITITYM9",
"TCK": "ZN"
},
"ProductSMCP": [
{
"SMCP": "01"
},
{
"SMCP2": "02"
}
]
}
]
}
下面是我规范化json对象的代码。在
^{pr2}$我想要的结果应该是这样的
id Description TypeLevel1 TypeLevel2 Currency \
25 3 YEAR US INTEREST LONG NAN
26 10 YEAR US INTEREST NAN USD
BBT TCT SMCP SMCP2 SCSP
NAN NAN 521 NAN 01
M9 ZN 01 02 NAN
然而,我得到的结果是:
Product.Currency Product.Description Product.Operational Product.TypeLevel1 \
0 NaN 3 YEAR NaN INTEREST
1 USD 10 YEAR True INTEREST
Product.TypeLevel2 ProductSMCP Xref.BBT Xref.SCSP \
0 LONG [{'SMCP': '01'}] NaN 96
1 LONG [{'SMCP': '01'}, {'SMCP2': '02'}] CITITYM9 NaN
Xref.TCK _id
0 NaN 25
1 ZN 26
如您所见,问题出在ProductSCMP,它没有完全展平数组。
一旦我们通过了第一次规范化,我将应用
lambda
来完成这项工作。在修剪列名
