I have some issue finding the right way to filter in my input json file using jolt as described in the following:

Input :

{
  "test1": 2242,
  "test2": 23456,
  "description": "desc, desc, desc",
  "name1": "foo",
  "active": true,
  "date1": "xx-xx-xx",
  "date2": "xx-xx-xx",
  "grade": "A",
  "quantity": 10,
  "information": "info, info, info",
  "favorite": "Y",
  "maxValue": 100,
  "approachTypeMin[zone=MAR, method=a]": "12",
  "approachTypeMax[zone=MAR, method=a]": "50",
  "approachTypeMin[zone=NOR, method=b]": "3",
  "approachTypeMax[zone=NOR, method=b]": "10"
}

This is my Spec

[
  {
    "operation": "shift",
    "spec": {
      "test1": "value1",
      "test2": "value2",
      "description": "desc1",
      "name1": "nameValue",
      "active": {
        "true": {
          "#Active": "status"
        },
        "false": {
          "#Inactive": "status"
        }
      },
      "date1": "beginDate",
      "date2": "endDate",
      "grade": {
        "*": {
          "$": "testGrade.value",
          "@(2,type)": "testGrade.type",
          "#2": "testGrade.defaultValue"
        }
      },
      "quantity": "qtn",
      "additionalInfo": "information",
      "favorite": "fvt",
      "maxValue": "max",
      "approachType*, method=*]": "test.&(0,2)"
    }
  }
]

This is my actual Output

{
  "value1" : 2242,
  "value2" : 23456,
  "desc1" : "desc, desc, desc",
  "nameValue" : "foo",
  "status" : "Active",
  "beginDate" : "xx-xx-xx",
  "endDate" : "xx-xx-xx",
  "testGrade" : {
    "value" : "A",
    "defaultValue" : "2"
  },
  "qtn" : 10,
  "fvt" : "Y",
  "max" : 100,
  "test" : {
    "A" : [ "12", "50" ],
    "B" : [ "3", "10" ]
  }
}

My issue is that i can't find a way to get something like the result above depending on the grade(e.g grade A==Approach method):

{
  "value1": 2242,
  "value2": 23456,
  "desc1": "desc, desc, desc",
  "nameValue": "foo",
  "status": "Active",
  "beginDate": "xx-xx-xx",
  "endDate": "xx-xx-xx",
  "value": "X",
  "testGrade": {
    "type": "A",
    "defaultValue": "2"
  },
  "qtn": "10",
  "fvt": "Y",
  "max": "100",
  "convertedApproachMin": 12,
  "convertedApproachMax": 50

}

Thanks for any help!

CodePudding user response：

Need to divide key names starting with approachType one more time in order to seperate them by means of Min and Max, to derive the lower case grade to match the extracted methods (a and b).

So, use the following specs :

[
  {
    "operation": "shift",
    "spec": {
      "test1": "value1",
      "test2": "value2",
      "description": "desc1",
      "name1": "nameValue",
      "active": {
        "true": {
          "#Active": "status"
        },
        "false": {
          "#Inactive": "status"
        }
      },
      "date1": "beginDate",
      "date2": "endDate",
      "grade": "&",
      "quantity": "qtn",
      "additionalInfo": "information",
      "favorite": "fvt",
      "maxValue": "max",
      "approachType*\\[zone*, method=*]": "cA&(0,1).&(0,3)"
    }
  },
  {
    "operation": "modify-overwrite-beta",
    "spec": {
      "grade_l": "=toLower(@(1,grade))"
    }
  },
  {
    "operation": "shift",
    "spec": {
      "*": "&",
      "grade_l": {
        "*": {
          "@(2,grade)": "testGrade.value",
          "#2": "testGrade.defaultValue",
          "@(2,cAMin.&)": "convertedApproachMin",
          "@(2,cAMax.&)": "convertedApproachMax"
        }
      }
    }
  },
  {
    "operation": "remove",
    "spec": {
      "grade": "",
      "cA*": ""
    }
  }
]
