Request for Assistance with Dynamic Visualization of Objects in Qlik

usuarioprueba991 — Wed, 17 Jan 2024 15:08:00 GMT

I'm currently developing an experimental application using the Qlik Embed API in a React environment. One of the features I am attempting to implement involves visualizing dynamically fetched objects from a specific sheet.My approach involves retrieving the object IDs into an array and subsequently iterating through this collection to dynamically generate visualizations using your QlikEmbed component. However, I'm struggling to get this to work as expected.
Could you please provide some guidance or potential solutions to resolve this issue? It would be greatly appreciated if you could point out any common pitfalls or considerations for this type of implementation.Thank you very much in advance for your assistance.

Hi @usuarioprueba991 are you trying to render existing charts or are you trying to create visualizations on the fly based on existing charts?
Could you please share with us which error you are facing and your code?

Hi @alex_colombo I'm trying to dynamically render objects that already exist within an app. I tried using Qlik Sense Dev Hub's EngineAPIExplorer with different methods, but I couldn't find one that returns a JSON with the object IDs related to a certain sheet

@usuarioprueba991 which API are you using for embed Qlik objects?

If you are looking for sheet ID, look at your url and you can find it. Having this sample url, in bold you have the sheet id: https://my_server/sense/app/355d73bc-a789-47eb-bd47-0ce8f5c69ab2/sheet/75876dbe-6a31-4761-ac63-733c975269e5/state/analysis.

For getting the Qlik Sense object ID for embedding, you have to open the Qlik Sense app and right click on an object, then click on Share and then on Embed. You will see the object id like below:

@alex_colombo I wonder if there is a way to obtain all the objectIds (more than one objectId) in an array to dynamically render the objects related to an specific sheet without needing to look for each one separately.
I'm using QlikEmbed with React

@usuarioprueba for doing this you need to use our Engine API for retrievieng the list of the sheets, and then get all the objects within this specific sheet.
I'd suggest to use enigma.js (a wrapper on top of Engina APIs) into your React web application. With that you can interact with Engine APIs and you can get the sheet list:

//qlikApp: qlik application opened with enigma const sheetDef = { "qInfo": { "qType": "SheetList" }, "qAppObjectListDef": { "qType": "sheet", "qData": { "title": "/qMetaDef/title", "description": "/qMetaDef/description", "thumbnail": "/thumbnail", "cells": "/cells", "rank": "/rank", "columns": "/columns", "rows": "/rows" } } } //Create sheetList object const sheetList = await qlikApp.createSessionObject(sheetDef) //Get all the sheets information, such as sheet ids const sheetsLayout = await sheetList.getLayout(); //Get specific sheet using sheet id const sheet = await qlikApp.getObject(sheetsLayout.qAppObjectList.qItems[0].qInfo.qId) //Get object list where you can find all the objects and their info such as position, chart id, chart name, etc.. const objectList = await sheet.getLayout()
