I've run into a bit of an interesting situation. I want to remove values from an array of hashes if a specific value in that array is a duplicate. Here's an example of the structure I'm working with:
[
{
"PCDBPart": {
"Category": {
"ID": 22,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 12,
"PositionID": 10
}
},
{
"PCDBPart": {
"Category": {
"ID": 22,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 12,
"PositionID": 10
}
},
{
"PCDBPart": {
"Category": {
"ID": 24,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 2,
"PositionID": 4
}
}
]
The issue I have is that the values in Position are duplicated often, making the array large. I want to return the array with hashes unique by the PositionID they contain.
I tried using my_array.uniq { |h| h.dig(:Position, :PositionID)}, but that just seems to return one value:
[
{
"PCDBPart": {
"Category": {
"ID": 22,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 12,
"PositionID": 10
}
},
]
Here's the desired output:
[
{
"PCDBPart": {
"Category": {
"ID": 22,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 12,
"PositionID": 10
}
},
{
"PCDBPart": {
"Category": {
"ID": 24,
"Name": "Wiper and Washer"
}
},
"Position": {
"Name": "Right",
"PCDBPositionID": 2,
"PositionID": 4
}
}
]
Does anybody have any suggestions on how to proceed?

I have an array :
{
"count": 8,
"id": "accountId",
"name": " Account Id",
"values": [
{
"count": 2,
"id": "1234456789000",
"name": "1234456789000"
},
{

},

},
{
"count": 2,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 1,
"id": "6ee26149-a156-4665-bd26-a6e46b49a70f",
"name": "6ee26149-a156-4665-bd26-a6e46b49a70f"
},
{
"count": 1,
"id": "927b48ce-efe4-4c20-98f0-ec6c54f59b45",
"name": "927b48ce-efe4-4c20-98f0-ec6c54f59b45"
}
]
}
And I have a 2nd array :
[
{
"count": 2,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 2,
"id": "1234456789000",
"name": "1234456789000"
}
]
The second array, I have filtered based on some requirement.
I want to replace the values from 1st array with second array.
Using typescript code.
Please help here.
If I understand question, you just need iterate by values array and find same id from second array.
function findAndSwitch(object1, array1): void {
object1.values = object1.values.map(el => {
const objToSwitch = array1.find(eleArr => eleArr.id === el.id);
if (objToSwitch) {
return el = objToSwitch;
} else {
return el;
}
});
}

Let's say your variable names are obj1 and arr2, respectively. First transform arr2 into an object obj2:
let obj2 = arr2.reduce((acc,cur) => ({...acc,[cur.id]:cur}),{});
Which now looks like this:
{
'432112426686': {
count: 20,
id: '432112426686',
name: '432112426686'
},
'1234456789000': {
count: 20,
id: '1234456789000',
name: '1234456789000'
}
}
Then transform obj1 based on obj2 as follows:
obj1.values = obj1.values.map(value => obj2[value.id] || value);
Please note that since the data in arr2 is identical to the corresponding data in obj1, I have altered the values of count property in arr2 in order to demonstrate that obj1 will be updated accordingly.
DEMO ONE
let obj1 = {
"count": 8,
"id": "accountId",
"name": " Account Id",
"values": [
{
"count": 2,
"id": "1234456789000",
"name": "1234456789000"
},
{
"count": 1,
"id": "135792468045",
"name": "135792468045"
},
{
"count": 1,
"id": "309983110022",
"name": "309983110022"
},
{
"count": 2,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 1,
"id": "6ee26149-a156-4665-bd26-a6e46b49a70f",
"name": "6ee26149-a156-4665-bd26-a6e46b49a70f"
},
{
"count": 1,
"id": "927b48ce-efe4-4c20-98f0-ec6c54f59b45",
"name": "927b48ce-efe4-4c20-98f0-ec6c54f59b45"
}
]
};
let arr2 = [
{
"count": 20,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 20,
"id": "1234456789000",
"name": "1234456789000"
}
];
let obj2 = arr2.reduce((acc,cur) => ({...acc,[cur.id]:cur}),{});
obj1.values = obj1.values.map(value => obj2[value.id] || value);
console.log( obj1 );
--
However, if all you want is to replace all the obj1.values with arr2, all you need is:
obj1.values = [...arr2];
And this will give rise to:
{
count: 8,
id: 'accountId',
name: ' Account Id',
values: [{
count: 20,
id: '432112426686',
name: '432112426686'
},
{
count: 20,
id: '1234456789000',
name: '1234456789000'
}
]
}

obj1.values = arr2;
console.log( obj1 );
This is my multi dimensional array.
Output should be in array2 structure.
I have tried many ways covert above array in easy but all came up with bulky code and lots of iteration.
Is there any easy way to do so?

Thanks in advance.
So you just want to have the original data as additional data attribute? This is simple using a forEach() loop in combination with the map() function:
array1.forEach((obj) => {
obj.category = obj.category.map((cat) => {
return {id: cat.id, name: cat.name, data: cat}
});
})
Hope this is what you're looking for :-)
I have a JSON with documents and each document has a few _childDocuments_ I want to search in the parent and get back the parents and facets on each parent separate
Here is a sample JSON
[{
"id": 1,
"productName": "Ford Explorer",
"_childDocuments_": [{
"id": 6,
"color": "blue",
"price": 1000
},
{
"id": 7,
"color": "red",
"price": 2000
}
]
},
{
"id": 1,
"productName": "Ford F150",
"_childDocuments_": [{
"id": 10,
"color": "blue",
"price": 5000
},
{
"id": 11,
"color": "red",
"price": 6000
}
]
},
{
"id": 2,
"productName": "Toyota Highlander",
"_childDocuments_": [{
"id": 8,
"color": "green",
"price": 1200
},
{
"id": 9,
"color": "red",
"price": 2000
}
]
}
]
I want when I search for Ford I should get back all Fords and in each root document get back facets of the children.
Something like this:
[{
"id": 1,
"productName": "Ford Explorer",
"facets": {
"count": 2,
"prices": {
"buckets": [{
"val": 2000,
"count": 1
},
{
"val": 3000,
"count": 1
}
]
}
}
},
{
"id": 1,
"productName": "Ford F150",
"facets": {
"count": 2,
"prices": {
"buckets": [{
"val": 5000,
"count": 1
},
{
"val": 6000,
"count": 1
}
]
}
}
}
]
This is what I got so far
q={!parent+which=type:parent}&json.facet={ "prices": {
"type": "range",
"field": "price",
"start": 1000,
"end": 1000,
"gap": 1000
}
,
}
But this is only returning facets on all child documents.
Thanks in advance
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 am trying to make a shopping cart API route and I am stuck with this problem because when I am using this statement $carts = \Cart::session($session)->getContent();
I get an object like this:
"cart": {
"1": {
"id": 1,
"name": "Tort cu biscuiți",
"price": 20,
"quantity": "1",
"attributes": {
"image_path": "http://127.0.0.1:8000/storage/images/AkiGKJdxjKNtyoVI034RPL1drLsMntUxLfzqZplV.jpeg"
},
"conditions": []
},
"2": {
"id": 2,
"name": "Tort cu biscuiți",
"price": 20,
"quantity": 2,
"attributes": {
"image_path": "http://127.0.0.1:8000/storage/images/IkAhenLttHWaRD58hNZ460ykWCq7q1sih3vI9H5V.jpeg"
},
"conditions": []
}
}
and I want to convet this to be array of objects. I tryied $cart->toArray(); and didn't work, also I tiyed (array) $cart and I get this:
"cart": {
"\u0000*\u0000items": {
"1": {
"id": 1,
"name": "Tort cu biscuiți",
"price": 20,
"quantity": "1",
"attributes": {
"image_path": "http://127.0.0.1:8000/storage/images/AkiGKJdxjKNtyoVI034RPL1drLsMntUxLfzqZplV.jpeg"
},
"conditions": []
},
"2": {
"id": 2,
"name": "Tort cu biscuiți",
"price": 20,
"quantity": 2,
"attributes": {
"image_path": "http://127.0.0.1:8000/storage/images/IkAhenLttHWaRD58hNZ460ykWCq7q1sih3vI9H5V.jpeg"
},
"conditions": []
}
}
}
may I know what is the problem?
You can do it manuel like this:
$carts = \Cart::session($session)->getContent();
if ($carts) {
$cartsArray = json_decode($carts);
foreach($cartsArray->cart as &$cart){
$cart = (array) $cart;
}
}
dd($cartsArray);
