Map to JSON with children under "children": [ .. ] JAVA - java

I have a map like this :
{
facility-1={facility-kind1={param1=XPath-1, param2=XPath-2},
facility-kind2={param1=XPath-1, param2=XPath-2}
},
facility-2={facility-kind1={param1=XPath-1, param2=XPath-2},
facility-kind2={param1=XPath-1, param2=XPath-2}
}
}
I want to format it to JSON with the children under "children": [ .. ] tag:
[
{"title": "Item 1"},
{"title": "Folder 2",
"children": [
{"title": "Sub-item 2.1"},
{"title": "Sub-item 2.2"}
]
},
{"title": "Folder 3",
"children": [
{"title": "Sub-item 3.1"},
{"title": "Sub-item 3.2"}
]
}
]
When I use JSON I don't get the children tag :
{
"facility-1": {
"facility-kind1": {
"param1": "XPath-1",
"param2": "XPath-2"
},
"facility-kind2": {
"param1": "XPath-1",
"param2": "XPath-2"
}
},
"facility-2": {
"facility-kind1": {
"param1": "XPath-1",
"param2": "XPath-2"
},
"facility-kind2": {
"param1": "XPath-1",
"param2": "XPath-2"
}
}
}
Which is not what I want.
How can I get a JSON formatted the way I want?

MongoDB : fields are excluded when invoke multiple lookup stages

db={
"dashboard": [
{
"_id": "dashboard1",
"name": "test",
"user": 1
}
],
"templatefolders": [
{
"dashboardId": "dashboard1",
"folderId": "folder123",
"name": "folder",
"region": "XXX"
}
],
"folders": [
{
"_id": "folder123"
}
],
"user": [
{
"_id": 1,
"name": "alaa"
}
],
}
this is my function:
db.dashboard.aggregate([
{
"$lookup": {
"from": "templatefolders",
"localField": "_id",
"foreignField": "dashboardId",
"as": "joinDashboard"
}
},
{
"$lookup": {
"from": "folders",
"localField": "joinDashboard.folderId",
"foreignField": "_id",
"as": "joinDashboard.joinFolder"
}
},
])
Result :
[
{
"_id": "dashboard1",
"joinDashboard": {
"joinFolder": [
{
"_id": "folder123"
}
]
},
"name": "test",
"user": 1
}
]

Why the fields name and region in collection templatefolders are excluded ?
I want to know why this behavior ? I don't like to use unwind because i have multiple collections with multiple refrence relation.
Your second $lookup, is overriding the joinDashboard key completely. Since you want joinFolder to be within joinDashboard, you can try nested lookups like this:
db.dashboard.aggregate([
{
$lookup: {
from: "templatefolders",
let: {
"boardId": "$_id"
},
pipeline: [
{
$match: {
$expr: {
$eq: [
"$dashboardId",
"$$boardId"
]
}
}
},
{
$lookup: {
from: "folders",
let: {
"folderId": "$folderId"
},
pipeline: [
{
$match: {
$expr: {
$eq: [
"$_id",
"$$folderId"
]
}
}
},
],
as: "joinFolder"
},
},
],
as: "joinDashboard"
}
}
])

Is there a way to use aggregation function to search for two fields for MongoDB/Java

What i would like to do is get all countries that have a region or subregion equal to "Southern Asia". Is there a function to perform compare both region and subregion to the string "Southern Asia"? I tried using filter but that didnt work out for me. The code below works fine to find regions that are equal to "Souther Asia"
Bson match = match(eq("region", "Southern Asia"));
This is an example of the json Data:

How to form post request body where resource contained multi reference resources from Java to FHIR api

I have to send request body as org.hl7.fhir.r4.model.CoverageEligibilityRequest which is contained Patient, Practitioner, Organization as below. This API will return Bundle response. I am using Java and Generic client from Hapi Fire library. There is provision to pass search parameter but the here I am having multilevel hierarchy of resource and input is big than usual. Can any one help me to handle this request in FHIR API.
Request Body as below,

Groovy remove from map

The list below contains a collection of id's
List id_wanted = ['3894586', '2786438236', '895673985']
Given the list above, How do I remove elements from the JSON below that match with the id above List?
JSON:
{
"animals": [
{
"name": "lion",
"countries": [
{
"name": "kenya",
"facts": [
{
"features": [
"young male"
],
"age": "2y",
"id": "2837492"
}
]
},
{
"name": "tanzania",
"facts": [
{
"features": [
"cub"
],
"age": "0y",
"id": "3894586"
}
]
},
{
"name": "south africa",
"facts": [
{
"features": [
"adult lioness"
],
"age": "10y",
"id": "495684576"
},
{
"features": [
"young female"
],
"age": "4y",
"id": "2786438236"
}
]
}
]
},
{
"name": "giraffe",
"countries": [
{
"name": "zambia",
"facts": [
{
"features": [
"ex captivity"
],
"age": "20y",
"id": "343453509"
}
]
},
{
"name": "kenya",
"facts": [
{
"features": [
"male"
],
"age": "17y",
"id": "85604586"
}
]
},
{
"name": "uganda",
"facts": [
{
"features": [
"young female"
],
"age": "4y",
"id": "895673985"
},
{
"features": [
"none"
],
"age": "11y",
"id": "39860394758936764"
}
]
}
]
}
]
}
For example, the following block would be removed from the JSON above because id matches with the List id_wanted
{
"features": [
"young female"
],
"age": "4y",
"id": "2786438236"
}
Assuming your json is a String in a variable inputJson, it's probably easier to build a new Json document from the original with those values filtered out:
import groovy.json.*
def json = new JsonSlurper().parseText(inputJson)
List id_wanted = ['3894586', '2786438236', '895673985']
def result = new JsonBuilder([
animals: json.animals.collect {[
name: "$it.name",
countries: it.countries.collect { [
name: "$it.name",
facts: it.facts.findAll { !(it.id in id_wanted) }
]}
]}
]).toString()
You can parse your original json and modify the resulted data structure in-place using handy *. spread operator:
def json = slurper.parseText(original)
json.animals*.countries*.facts*.each { facts ->
facts.removeAll { fact -> fact.id in id_wanted }
}
def filtered = new JsonBuilder(json).toPrettyString()
println(filtered)
Output (with facts from id_wanted removed):
{
"animals": [
{
"name": "lion",
"countries": [
{
"name": "kenya",
"facts": [
{
"features": [
"young male"
],
"age": "2y",
"id": "2837492"
}
]
},
{
"name": "tanzania",
"facts": [
]
},
{
"name": "south africa",
"facts": [
{
"features": [
"adult lioness"
],
"age": "10y",
"id": "495684576"
}
]
}
]
},
{
"name": "giraffe",
"countries": [
{
"name": "zambia",
"facts": [
{
"features": [
"ex captivity"
],
"age": "20y",
"id": "343453509"
}
]
},
{
"name": "kenya",
"facts": [
{
"features": [
"male"
],
"age": "17y",
"id": "85604586"
}
]
},
{
"name": "uganda",
"facts": [
{
"features": [
"none"
],
"age": "11y",
"id": "39860394758936764"
}
]
}

How to transform row data in cassandra to nested json with respect to the columns

I have the following table in cassandra. (row level data)
The last column(ENGINE_CC) is unique. I want to categories the available data with respect to that column.
Required output in form of nested json:
{
"VECHILE_TYPE": [
{
"name": "Two Wheeler",
"MODEL": [
{
"name": "Bike",
"SUBMODEL": [
{
"name": "Super Bike",
"VECHILE_NAME": [
{
"name": "Suzuki_Hayabusa",
"Engine_CC": [
"250",
"300",
"450"
]
},
{
"name": "GSX",
"Engine_CC": [
"225",
"200"
]
}
]
},
{
"name": "Street Bike",
"VECHILE_NAME": [
{
"name": "Gixxer",
"Engine_CC": [
"175",
"150"
]
}
]
}
]
}
]
},
{
"name": "Four Wheeler",
"MODEL": [
{
"name": "Economic",
"SUBMODEL": [
{
"name": "Hatchback",
"VECHILE_NAME": [
{
"name": "I10",
"Engine_CC": [
"1000",
"1200"
]
},
{
"name": "Santro",
"Engine_CC": [
"800",
"900"
]
}
]
}
]
}
]
}
]
}
Could someone suggest
1)JAVA model for the nested json
2)How to add the row level data to the model
Is any library available to achieve this. This is basically a design question. Any suggestions ? Thanks in advance.
