We need to convert the object to an Array of objects and do map on the field but the field is incremental like field1, field2 which is where we got stuck.
I tried the below code:
output application/json
---
payload.main.field map(value) -> {
"name": value.name,
"age": value.age,
"location": value.location[0].country
}
Input:
{
"main": {
"field1": {
"name": "value",
"age": 20,
"address": {
"location": [
{
"country": "US",
"zipcode": 1234
},
{
"country": "US",
"zipcode": 1234
}
]
}
},
"field2": {
"name": "pqr",
"age": 23,
"address": {
"location": [
{
"country": "CA",
"zipcode": 1235
},
{
"country": "US",
"zipcode": 1234
}
]
}
},
"field3": {
"name": "abc",
"age": 22,
"address": {
"location": [
{
"country": "BU",
"zipcode": 1236
},
{
"country": "US",
"zipcode": 1234
}
]
}
}
}
}
For the above Input, Below is the expected response.
Expected Output:
{
"main": [
{
"name": "value",
"age": 20
"location": "US"
},
{
"name": "pqr",
"age": 23
"location": "CA"
},
{
"name": "abc",
"age": 22
"location": "BU"
}
]
}
For location, it will be like location[0].country when the array size is not 0 and country not null.
output application/json
---
main : payload.main pluck $ map {
"name": $.name,
"age": $.age,
"location": if( sizeOf($.address.location) !=0) $.address.location[0].country else "N/A"
}

I have the following JSON object from which I'd like to extract a specific property
{
"gender": "male",
"age": 36,
"profession": "teacher",
"hobbies": [
{
"id": 28,
"name": "gardening"
},
{
"id": 878,
"name": "Football"
},
{
"id": 35,
"name": "Reading"
},
{
"id": 10751,
"name": "Socialising"
}
],
"Country": "Sweden",
"id": 4542236,
}
Lets say I wanted to create a new object that hold only the "hobbies" property with all the values like this
{
"hobbies": [
{
"id": 28,
"name": "gardening"
},
{
"id": 878,
"name": "Football"
},
{
"id": 35,
"name": "Reading"
},
{
"id": 10751,
"name": "Socialising"
}
]
}
Since the JSON is coming from an external API I have no control on future positioning (index) of any properties
I have an array as the source. I want to transform source into result by using Groovy.
I don't see any similar question. That's why I post here.
I tried to get the first member in the family and put all other members into a subList with this code but it failed
source.each{ family -> family.each{
member -> member.get(0).collate(1,family.size()-1)
}
}
source:
[
[{
"id": "0001",
"role": "parent",
"age": 30
},
{
"id": "0002",
"role": "child",
"age": 1
},
{
"id": "0003",
"role": "child",
"age": 3
}
],
[{
"id": "0004",
"role": "parent",
"age": 31
},
{
"id": "0005",
"role": "child",
"age": 5
}
]
]
result:
[{
"id": "0001",
"role": "parent",
"age": 30,
"children": [{
"id": "0002",
"role": "child",
"age": 1
},
{
"id": "0003",
"role": "child",
"age": 3
}
]
},
{
"id": "0004",
"role": "parent",
"age": 31,
"children": [{
"id": "0005",
"role": "child",
"age": 5
}]
}]
You can shape the data by adding the "parent" map with a new map only containing the children (+ in groovy does that merge). E.g.:
def data = new groovy.json.JsonSlurper().parseText('[[{ "id": "0001", "role": "parent", "age": 30 }, { "id": "0002", "role": "child", "age": 1 }, { "id": "0003", "role": "child", "age": 3 } ], [{ "id": "0004", "role": "parent", "age": 31 }, { "id": "0005", "role": "child", "age": 5 }]]')
println(data.collect{ groups ->
// XXX
groups.find{ it.role=="parent" } + [children: groups.findAll{it.role=="child"}]
})
// => [[id:0001, role:parent, age:30, children:[[id:0002, role:child, age:1], [id:0003, role:child, age:3]]], [id:0004, role:parent, age:31, children:[[id:0005, role:child, age:5]]]]
I have an array structure like this.
[
{
"id": "1",
"name": "John",
"city": "NY"
},
{
"id": "2",
"name": "Gerold",
"city": "LA"
},
{
"id": "3",
"name": "Stuart",
"city": "Boston"
}
]
I need $scope like below for my autocomplete search.
$scope.name=["john","Gerold","Stuart"];
$scope.city=["NY","LA","Boston"];
can anyone help to get this using angularjs controller.
Thanks in Advance.!
Use MAP
$scope.users = [
{
"id": "1",
"name": "John",
"city": "NY"
},
{
"id": "2",
"name": "Gerold",
"city": "LA"
},
{
"id": "3",
"name": "Stuart",
"city": "Boston"
}
];
$scope.cities = $scope.users.map(function(obj){
return obj.city;
});
console.log($scope.cities);
You can also create a helper function that would do that for you and you don't have to define a map per function that you want, and you do it in just one run (hence just a bit faster)
Sample here ;)
var myArray = [
{
"id": "1",
"name": "John",
"city": "NY"
},
{
"id": "2",
"name": "Gerold",
"city": "LA"
},
{
"id": "3",
"name": "Stuart",
"city": "Boston"
}
]
function toScope(scopedPropertieNames, array) {
scopedPropertieNames.forEach(function(propertyName) {
if (! $scope[propertyName]) {
$scope[propertyName] = []
}
});
array.forEach(function (objecInArray) {
scopedPropertieNames.forEach(function(propertyName) {
$scope[propertyName].push(objecInArray[propertyName])
})
});
}
toScope(['name', 'city'], myArray);
console.log($scope) //{name: Array[3], city: Array[3]}
You can use MAP..
$scope.YourBigArray = [{
"id": "1",
"name": "John",
"city": "NY"
}, {
"id": "2",
"name": "Gerold",
"city": "LA"
}, {
"id": "3",
"name": "Stuart",
"city": "Boston"
}];
$scope.names = $scope.YourBigArray.map(function(object) {
return object.name;
});
$scope.cities = $scope.YourBigArray.map(function(object) {
return object.city;
});
You can do a filter to use unique things in array of names and cities..
function filterForDuplicate(things) {
return things.filter(function(item, pos) {
return things.indexOf(item) === pos;
});
}
I have an angular application which uses a significantly large shared model. Currently, when a user presses save the entire model is posted to a RESTful service. Ideally I would only like to post the fields that have changed. Since this is a shared model I do not have access to form validation states such as dirty/pristine etc. The idea I can think of is to have two models, the original and the modified and compare these.
Original Model
{
"firstName": "John",
"lastName": "Smith",
"isAlive": true,
"age": 25,
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021-3100"
},
"phoneNumbers": [
{
"id": "123",
"number": "212 555-1234"
},
{
"id": "456",
"number": "646 555-4567"
},
{
"id": "789",
"number": "123 456-7890"
}
],
"children": [],
"spouse": null
}
Changed Model
{
"firstName": "Jane",
"lastName": "Smith",
"isAlive": true,
"age": 50,
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021-3100"
},
"phoneNumbers": [
{
"id": "123",
"number": "1234567890"
},
{
"id": "456",
"number": "646 555-4567"
},
{
"id": "789",
"number": "123 456-7890"
}
],
"children": [],
"spouse": null
}
Data Posted - This is what I need!
{
"firstName": "Jane",
"age": 50,
"phoneNumbers": [
{
"id":"123",
"number": "1234567890"
}
]
}
How can I achieve this? I need the changed fields including any fields called id!
You'll need something like this. Working Fiddle: https://jsfiddle.net/jyyyLaot/
function filter(obj1, obj2) {
var result = {};
for(key in obj1) {
if(obj2[key] != obj1[key]) result[key] = obj2[key];
if(typeof obj2[key] == 'array' && typeof obj1[key] == 'array')
result[key] = arguments.callee(obj1[key], obj2[key]);
if(typeof obj2[key] == 'object' && typeof obj1[key] == 'object')
result[key] = arguments.callee(obj1[key], obj2[key]);
}
return result;
}
