[英]Flatten a JSON document using jq by filtering an array by keys
I have a JSON in the following format:我有一个 JSON 格式如下:
{
"subFields": [
{
"id": "question_1",
"type": "radioGroup",
"description": "Description1",
"title": "title1",
"subFields": [
{
"type": "radio",
"label": "Yes",
"value": 1
},
{
"type": "radio",
"label": "No",
"value": 0
},
{
"uiComponent": "SmallContent",
"componentProps": {
"text": "* If the answer to the above question is “Yes”, please contact the Support immediately."
}
}
]
},
{
"uiComponent": "Spacer"
},
{
"id": "question_2",
"type": "radioGroup",
"description": "Description2",
"title": "Title2",
"subFields": [
{
"type": "radio",
"label": "Label - Value 1",
"value": 1
},
{
"type": "radio",
"label": "Label - Value 2",
"value": 2
},
{
"type": "radio",
"label": "Label - Value 3",
"value": 3
},
{
"type": "radio",
"label": "Other",
"value": 13,
"subFields": [
{
"id": "question_2a",
"type": "string",
"condition": {
"type": "BinaryExpression",
"operator": "==",
"left": {
"type": "Identifier",
"name": "question_2"
},
"right": {
"type": "Literal",
"value": 13
}
}
}
]
}
]
},
{
"id": "question_2_b",
"style": {
"marginTop": "30px"
},
"type": "radioGroup",
"description": "Description3",
"title": "",
"subFields": [
{
"type": "radio",
"label": "Label - Radio 1",
"value": 1
},
{
"type": "radio",
"label": "Label - Radio 2",
"value": 2
},
{
"type": "radio",
"label": "Label - Radio 3",
"value": 3
}
]
},
{
"uiComponent": "Spacer"
},
{
"id": "question_3",
"type": "radioGroup",
"description": "Description3",
"title": "Title3",
"subFields": [
{
"type": "radio",
"label": "Yes",
"value": 1
},
{
"type": "radio",
"label": "No",
"value": 0
}
]
},
{
"uiComponent": "Spacer"
},
{
"condition": {
"type": "BinaryExpression",
"operator": "==",
"left": {
"type": "Identifier",
"name": "signer_type"
},
"right": {
"type": "Literal",
"value": "entity"
}
},
"subFields": [
{
"uiComponent": "Spacer"
},
{
"id": "question_4",
"type": "radioGroup",
"description": "Description_4",
"title": "Title_4",
"subFields": [
{
"type": "radio",
"label": "Yes",
"value": 1
},
{
"type": "radio",
"label": "No",
"value": 0
}
]
},
{
"uiComponent": "Spacer"
}
],
"uiComponent": "Block"
},
{
"uiComponent": "Spacer"
}
],
"uiComponent": "Container"
}
and I would like to generate the following output:我想生成以下 output:
[
{
"id": "question_1",
"title": "title1",
"description": "Description1",
"type": "radioGroup",
"questions": "radio,Yes,1"
},
{
"id": "question_1",
"title": "title1",
"description": "Description1",
"type": "radioGroup",
"questions": "radio,No,0"
},
{
"id": "question_2",
"title": "Title2",
"description": "Description2",
"type": "radioGroup",
"questions": "radio,Label - Value 1,1"
},
{
"id": "question_2",
"title": "Title2",
"description": "Description2",
"type": "radioGroup",
"questions": "radio,Label - Value 2,2"
},
{
"id": "question_2",
"title": "Title2",
"description": "Description2",
"type": "radioGroup",
"questions": "radio,Label - Value 3,3"
},
{
"id": "question_2_b",
"title": "",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,Label - Value 1,1"
},
{
"id": "question_2_b",
"title": "",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,Label - Value 2,2"
},
{
"id": "question_2_b",
"title": "",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,Label - Value 3,3"
},
{
"id": "question_3",
"title": "Title3",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,Yes,1"
},
{
"id": "question_3",
"title": "Title3",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,No,0"
}
]
or in alternative a reduced version:或替代一个简化版本:
[
"question_1",
"title1",
"Description1",
"radioGroup",
"radio,Yes,1",
"radio,No,0"
],
[
"question_2",
"title2",
"Description2",
"radioGroup",
"radio,Label - Value 1,1",
"radio,Label - Value 2,2",
"radio,Label - Value 3,3",
],
[
"question_2_b",
"Description3",
"radioGroup",
"radio,Label - Value 1,1",
"radio,Label - Value 2,2",
"radio,Label - Value 3,3",
],
[
"question_3",
"Title3",
"Description3",
"radioGroup",
"radio,Yes,1",
"radio,No,0"
]
The objective is to get only the objects that contain the id (to remove the {"uiComponent": "Spacer"} objects) and get only the subFields with these tags inside the array:目标是仅获取包含 id 的对象(以删除{"uiComponent": "Spacer"}对象)并仅获取数组内具有这些标签的子字段:
"subFields": [
{
"type": "xxxx",
"label": "xxxx",
"value": xxxx
},
I was able to flatten the JSON array by using the following JQ pattern:通过使用以下 JQ 模式,我能够展平 JSON 阵列:
.subFields[] | select(has("id") and .id != null)| {id: .id, type: .type, description: .description, anwers: .subFields}
and generated this result:并产生了这个结果:
{
"id": "question_1",
"type": "radioGroup",
"description": "Description1",
"anwers": [
{
"type": "radio",
"label": "Yes",
"value": 1
},
{
"type": "radio",
"label": "No",
"value": 0
},
{
"uiComponent": "SmallContent",
"componentProps": {
"text": "* If the answer to the above question is “Yes”, please contact the Support immediately."
}
}
]
}
{
"id": "question_2",
"type": "radioGroup",
"description": "Description2",
"anwers": [
{
"type": "radio",
"label": "Label - Value 1",
"value": 1
},
{
"type": "radio",
"label": "Label - Value 2",
"value": 2
},
{
"type": "radio",
"label": "Label - Value 3",
"value": 3
},
{
"type": "radio",
"label": "Other",
"value": 13,
"subFields": [
{
"id": "question_2a",
"type": "string",
"condition": {
"type": "BinaryExpression",
"operator": "==",
"left": {
"type": "Identifier",
"name": "question_2"
},
"right": {
"type": "Literal",
"value": 13
}
}
}
]
}
]
}
{
"id": "question_2_b",
"type": "radioGroup",
"description": "Description3",
"anwers": [
{
"type": "radio",
"label": "Label - Radio 1",
"value": 1
},
{
"type": "radio",
"label": "Label - Radio 2",
"value": 2
},
{
"type": "radio",
"label": "Label - Radio 3",
"value": 3
}
]
}
{
"id": "question_3",
"type": "radioGroup",
"description": "Description3",
"anwers": [
{
"type": "radio",
"label": "Yes",
"value": 1
},
{
"type": "radio",
"label": "No",
"value": 0
}
]
}
My problem is that I don't know how to remove these sections:我的问题是我不知道如何删除这些部分:
{
"uiComponent": "SmallContent",
"componentProps": {
"text": "* If the answer to the above question is “Yes”, please contact the Support immediately."
}
}
and和
"subFields": [
{
"id": "question_2a",
"type": "string",
"condition": {
"type": "BinaryExpression",
"operator": "==",
"left": {
"type": "Identifier",
"name": "question_2"
},
"right": {
"type": "Literal",
"value": 13
}
}
}
]
I played a little bit arround with this jq for the question_3 only:我只为 question_3 使用了这个 jq:
.subFields[] | {id: .id, title: .title, description: .description, type: .type, subFields: .subFields} | select(has("id") and .id != null) | select(.id=="question_3") | {id: .id, title: .title, description: .description, type: .type, questions: (.subFields[]|join(","))}
and produced this result:并产生了这个结果:
{
"id": "question_3",
"title": "Title3",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,Yes,1"
}
{
"id": "question_3",
"title": "Title3",
"description": "Description3",
"type": "radioGroup",
"questions": "radio,No,0"
}
and also并且
.subFields[] | {id: .id, title: .title, description: .description, type: .type, subFields: .subFields} | select(has("id") and .id != null) | select(.id=="question_3") | [.id, .title, .description, .type, (.subFields[]|join(","))]
resulting on this:结果是:
[
"question_3",
"Title3",
"Description3",
"radioGroup",
"radio,Yes,1",
"radio,No,0"
]
Can you help me improve those JQ pattern I created to get the intended results?你能帮我改进我创建的那些 JQ 模式以获得预期的结果吗?
Thanks in advance!提前致谢!
The following produces your first alternative:以下产生您的第一个替代方案:
.subFields[]
| select(.id?)
| { id, title, description, type} +
(.subFields[]
| select(.type?)
| [.type,.label,.value] | join(",")
| { questions: .} )
Notice the two select()
filters.注意两个
select()
过滤器。
