I know that this is close to a duplicate but I can't get the code to work. I have an object that I need to filter and I'm currently trying to emulate the accepted as an answer the code at Javascript filtering nested arrays
My data object is:
[{
"project_num": "5R01DA012513-23",
"principal_investigators": [{
"profile_id": 2076451,
"full_name": "PK",
"title": ""
}]
},
{
"project_num": "5R01DK118529-03",
"principal_investigators": [{
"profile_id": 8590844,
"full_name": "HW",
"title": "PROFESSOR, SCIENTIFIC DIRECTOR"
}]
},
{
"project_num": "3R01AA025365-05S1",
"principal_investigators": [{
"profile_id": 8730036,
"full_name": "JJ",
"title": "ASSOCIATE PROFESSOR OF PSYCHIATRY"
}]
},
{
"project_num": "1R01HL163963-01",
"principal_investigators": [{
"profile_id": 2084037,
"full_name": "KH",
"title": "ASSOCIATE PROFESSOR"
},
{
"profile_id": 11309656,
"full_name": "AM",
"title": "RESEARCH ASSISTANT PROFESSOR"
}
]
},
{
"project_num": "5R25HL092611-15",
"principal_investigators": [{
"profile_id": 1886512,
"full_name": "CW",
"title": "P"
}]
}
]
and my JavaScript code is:
let payLoad = 1886512
const result = this.reporterData.map(t => {
const principal_investigators = t.principal_investigators.filter(d =>
d.profile_id === payLoad);
return { ...t,
principal_investigators
};
})
I need to pass in a profile_id as a payload and return the objects that will fill a data table.
The data can be 1000's of items and the principla_investigators can be multiple entries. When I use the code that I have it return all of the objects. Can someone point out my error? Thanks
You can try doing like this:
const result = this.reporterData.filter((t) => {
const principal_investigators = t.principal_investigators.filter((d) => d.profile_id === payLoad)
return (principal_investigators.length > 0)
})
I understand that you want an array with all the investigators matching that ID, right?
Try this:
const result = this.reporterData.reduce((previous, current) => {
if (current.principal_investigators) {
current.principal_investigators.forEach(pi => {
if (pi.profile_id === payLoad) {
previous.push(current)
}
});
}
return previous
}, [])
You can also do for loops with the same result:
const result = [];
for (project of this.reporterData) {
if (project.principal_investigators) {
for (pi of project.principal_investigators) {
if (pi.profile_id == payLoad) {
result.push(pi);
}
}
}
}

I want to create a nested filter in js
when I filter my array primary data is affected and changed but I need preliminary data to remove filters
my js code :
let result = companies;
result.map((item, i) => {212
let rows = [...result[i].table.table_rows].filter((item3) => {
return Object.keys(item3).some(i => item3[i][key] === value[key]);
});
result[i].table.table_rows = [...rows];
return result[i];
});
arrayFilter(result);
my data is:
{
"companies": [
{
"company": {
"name": "company 1"
},
"table": {
"table_rows": [
{
"cells": {
"product_name": "prod1",
"pa_size": "12"
}
},
{
"cells": {
"product_name": "prod2",
"pa_size": "15"
}
}
]
}
},
{
"company": {
"name": "company 2"
},
"table": {
"table_rows": [
{
"cells": {
"product_name": "prod2-1",
"pa_size": "12"
}
},
{
"cells": {
"product_name": "prod2-2",
"pa_size": "18"
}
}
]
}
}
]
}
I tried many ways to solve this problem, but I did not get the right answer
Your question is not clear, the point I have understand that you wanted to filter the array "table_rows" located inside each companies array object? map and filter returns new array, so the solution for this is:
result = result.companies.map((item, i) => {
const newItem = {...item};
let rows = newItem .table.table_rows.filter((item3) => {
return Object.keys(item3).some(i => item3[i][key] === value[key]);
});
newItem.table_rows = [...rows];
return newItem ;
});
arrayFilter(result);
I have two json files that I would like to combine into a single json object that can be read on my front end.
fragments.json
[
{
"id": 2,
"title": "John Smith is nice",
"reports": "1,2",
"entities": 1,
}
]
entities.json
[
{
"id": 1,
"fragments": 2,
"name": "John SMITH",
"dateOfBirth": "4/24/1967",
}
]
Desired Result.json
I want to show all the entities that are connected to any given fragment.
[
{
"id":2,
"title":"John Smith is nice",
"reports":"1,2",
"entities":{
"id":1,
"fragments":2,
"name":"John SMITH",
"dateOfBirth":"4/24/1967"
}
}
]
Here's my code so far:
router.get('/sprint-3/:prototype/report/:reportId', function (req, res) {
const slug = +req.params.reportId
const report = reports.find(({ id }) => id === slug);
const reportFragments = fragments.filter(({ reports }) => reports.includes(report.id) );
reportFragments.forEach(fragment => {
const reportEntities = entities.filter(({ fragments }) => fragments === fragment.id );
reportFragments.push(reportEntities);
console.log('New', reportFragments)
});
res.render("sprint-3/prototype-1/report", { report: report, fragments: reportFragments });
});
I've been looking at .push as a way of doing this, but currently it appends the entities to the end of the reportFragments rather than nesting inside each of them.
You can use reduce like so
const reportFragments = [{
"id": 2,
"title": "John Smith is nice",
"reports": "1,2",
"entities": 1,
}]
const entities = [{
"id": 1,
"fragments": 2,
"name": "John SMITH",
"dateOfBirth": "4/24/1967",
}]
const merged = reportFragments.reduce((acc, curr) => {
const match = entities.filter(ent => ent.fragments === curr.id);
return [...acc, ({
id: curr.id,
title: curr.title,
reports: curr.reports,
...{
entities: match
}
})]
}, [])
console.log(merged)
I'm trying to use paularmstrong/normalizr on JSON that comes from FractalTransformer and whose nested childs have "data" attribute. Example of JSON:
{
"data": {
"object": "Offer",
"id": "5g6aqocew4qjzl40",
"real_id": 26,
"name": "Random Name",
"created_at": {
"date": "2019-06-18 11:13:08.000000",
"timezone_type": 3,
"timezone": "UTC"
},
"readable_created_at": "1 year ago",
"site": {
"data": {
"object": "Site",
"id": "65zody8vj29vlegd",
"name": "Test Site",
"real_id": 1
}
},
"countries": {
"data": [
{
"object": "Country",
"code": "US",
"name": "United States"
},
{
"object": "Country",
"code": "DE",
"name": "Germany"
}
]
}
},
"meta": {
"include": [
"site",
"countries"
],
"custom": []
}
}
Schemas I use:
export const offerSchema = new schema.Entity('offers')
export const siteSchema = new schema.Entity('sites', {}, {
processStrategy: (value) => {
return { ...value.data }
},
idAttribute: (value) => {
return value.data.id
},
})
export const countrySchema = new schema.Entity('countries')
offerSchema.define({
site: siteSchema,
countries: [countrySchema],
})
Now the issue is that I remove 'data' from the site since it's just one object successfully, but I can't do it in the country case. Whatever I tried with custom processStrategy fails, as country is object that has data which is array (I assume this is where the issue is, going from Entity to Array). And in idAttribute function I always get complete array so can't determine the ID of single entry. So the end result is that the ID of countries is undefined. Any ides?
I actually managed with another approach. I added processStrategy on the parent, 'Offer' in this case, so all 'data' parts get stripped before they reach other child schemas.
const normalizrStripDataOptions = {
processStrategy: (value) => {
const ret = { ...value }
Object.keys(ret).forEach((key) => {
if (ret[key] !== null) {
if (ret[key].data && Array.isArray(ret[key].data)) {
ret[key] = [...ret[key].data]
}
if (ret[key].data && typeof ret[key].data === 'object') {
ret[key] = { ...ret[key].data }
}
}
})
return ret
},
}
export const offerSchema = new schema.Entity('offers', {}, normalizrStripDataOptions)
export const siteSchema = new schema.Entity('sites')
export const countrySchema = new schema.Entity('countries')
offerSchema.define({
site: siteSchema,
countries: [countrySchema],
})
let data = {
"rec": [{
"id": "25837",
"contentId": "25838"
},
{
"id": "25839",
"contentId": "25838"
},
{
"id": "25838"
},
{
"id": "25636",
"contentId": "25837"
}, {
"id": "25640",
"contentId": "25839"
}
]
};
I have a javascript object which I have to manipulate to below format.
{
"childern": [{
"id": "25838",
"childern": [{
"id": "25837",
"contentId": "25838",
"childern": [{
"id": "25636",
"contentId": "25837"
}]
},
{
"id": "25839",
"contentId": "25838",
"childern": [{
"id": "25640",
"contentId": "25839"
}]
}
]
}]
}
If any object dont have contentId it should be at parent level. then all the objects having contentId same as parent id should be at its child level and so on.
I have created a fiddle here but logic is not completed. Any idea or reference to achieve this.
You could create recursive function with reduce method to get the desired result.
let data = {"rec":[{"id":"25837","contentId":"25838"},{"id":"25839","contentId":"25838"},{"id":"25838"},{"id":"25636","contentId":"25837"},{"id":"25640","contentId":"25839"}]}
function nest(data, pid) {
return data.reduce((r, e) => {
if (pid == e.contentId) {
const obj = { ...e }
const children = nest(data, e.id);
if (children.length) obj.children = children
r.push(obj)
}
return r;
}, [])
}
const result = nest(data.rec);
console.log(result[0])
My target is if the id from digital_assets and products matches then get the value of URL fro digital_assets and ProductName from products object. I'm able to traverse through the object and get the values of digital_assets and products but need some help to compare these two objects based on IDs to get the value of URL and ProductName. Below is what I've done so far.
var data = [{
"digital_assets": [{
"id": "AA001",
"url": "https://via.placeholder.com/150"
},{
"id": "AA002",
"url": "https://via.placeholder.com/150"
}]
}, {
"products": [{
"id": ["BB001", "AA001"],
"ProductName": "PROD 485"
},{
"id": ["BB002", "AA002"],
"ProductName": "PROD 555"
}]
}
];
$.each(data, function () {
var data = this;
//console.log(data);
$.each(data.digital_assets, function () {
var dAssets = this,
id = dAssets['id'];
// console.log(id);
});
$.each(data.products, function () {
var proData = this,
prod_id = proData['id'];
// console.log(prod_id);
$.each(prod_id, function () {
var arr_id = this;
console.log(arr_id);
});
});
});
Do I need to create new arrays and push the values into the new arrays? Then concat() these array to one. ? Bit lost any help will be appreciated.
Here is one way you can do this via Array.reduce, Array.includes, Object.entries and Array.forEach:
var data = [{ "digital_assets": [{ "id": "AA001", "url": "https://via.placeholder.com/150" }, { "id": "AA002", "url": "https://via.placeholder.com/150" } ] }, { "products": [{ "id": ["BB001", "AA001"], "ProductName": "PROD 485" }, { "id": ["BB002", "AA002"], "ProductName": "PROD 555" } ] } ]
const result = data.reduce((r,c) => {
Object.entries(c).forEach(([k,v]) =>
k == 'digital_assets'
? v.forEach(({id, url}) => r[id] = ({ id, url }))
: v.forEach(x => Object.keys(r).forEach(k => x.id.includes(k)
? r[k].ProductName = x.ProductName
: null))
)
return r
}, {})
console.log(Object.values(result))
You can use Array.prototype.find, Array.prototype.includes and Array.prototype.map to achieve this very gracefully.
let data = [
{
"digital_assets": [
{
"id": "AA001",
"url": "https://via.placeholder.com/150"
},
{
"id": "AA002",
"url": "https://via.placeholder.com/150"
}
]
},
{
"products": [
{
"id": ["BB001", "AA001"],
"ProductName": "PROD 485"
},
{
"id": ["BB002","AA002"],
"ProductName": "PROD 555"
}
]
}
];
// Find the 'digital_assets' array
let assets = data.find(d => d['digital_assets'])['digital_assets'];
// Find the 'products' array
let products = data.find(d => d['products'])['products'];
// Return an array of composed asset objects
let details = assets.map(a => {
return {
id : a.id,
url : a.url
name : products.find(p => p.id.includes(a.id)).ProductName
};
});
console.log(details);
changed answer to fit your needs:
var data = [
{
"digital_assets": [
{
"id": "AA001",
"url": "https://via.placeholder.com/150"

let matchingIds = [];
let data_assetsObject = data.find(element => {
return Object.keys(element).includes("digital_assets")
})
let productsObject = data.find(element => {
return Object.keys(element).includes("products")
})
data_assetsObject["digital_assets"].forEach(da => {
productsObject["products"].forEach(product => {
if (product.id.includes(da.id)){
matchingIds.push({
url: da.url,
productName: product.ProductName

Hope that helped. If you dont want to use a new array, you could also store the respective data within the element you are looping through.
Edit:
I think i know why i got downvoted. My example works by making data an object, not an array. changed the snippet to show this more clearly.
Why is data an array anyway? Is there any reason for this or can you just transform it to an object?
Edit nr2:
changed the code to meet the expectations, as i understood them according to your comments. it now uses your data structure and no matter whats in data, you can now search for the objects containing the digital_assets / products property.
cheers
https://jsfiddle.net/2b1zutvx/
using map.
var myobj = data[0].digital_assets.map(function(x) {
return {
id: x.id,
url: x.url,
ProductName: data[1].products.filter(f => f.id.indexOf(x.id) > -1).map(m => m.ProductName)
};
});
