Populate With Item Reference

This method allows to populate items with item reference. That means you can connect items from different applications by ite reference. It allows to take data from certain field and populate another item with it. populatedWithItemRef can make such connections between a big number of applications.

This method accepts six arguments:

Name	Type	Description
sorceItemsRef	`array`	items that are used as reference for item_ref
srcFieldIdToCompare	`number`	field ID that is used to find similar items in source and destination arrays
destinationItems	`array`	items that are used to save item_ref to sorseItemsRef
destFieldIdToCompare	`number`	field ID that is used to find similar items in destination array
destFieldForRef	`number`	contains the ID of field where item_ref will be saved
app_id	`number`	application ID that is used to generate item_ref value

At first populateWithItemRef checks connection between sorceItemsRef and srcFieldIdToCompare. It does it with the help of srcFieldIdToCompare and destFieldIdToCompare. If the connection is detected, destFieldForRef will be updated with source item reference.

Item Reference

The destination item will have the object reference as a field_value. It consists of source application ID and source item ID:

{
    "field_value": "27823.2987934"
}

More detail about item reference you can read in Item Reference.

Example

import GudHub from '@gudhub/core';
const gudhub = await new GudHub();
const APPID = "27823";

let srcFieldIdToCompare = 645888;

let destFieldIdToCompare = 645900;

let destFieldForRef = 648741;

let sorceItemsRef = [{
  "item_id": 2987934,
  "fields": [{
      "field_id": 645888,
      "field_value": "GudHub",
      },
      {
        "field_id": 645887,
        "field_value": "John",
      }]
  }
];

let destinationItems = [{
    "item_id": 2993230,
    "fields": [{
        "field_id": 645900,
        "field_value": "GudHub",
        },
        {
          "field_id": 648741,
          "field_value": "Johana",
          }]
  }
];


// populate items with item reference
let populatedWithItemRef = gudhub.populateWithItemRef(sorceItemsRef, srcFieldIdToCompare, destinationItems, destFieldIdToCompare, destFieldForRef, APPID)
 
populatedWithItemRef.forEach(item => {
  console.log("item_id:", item.item_id)
  console.log(item.fields)
});

The method returns an array of objects which in turn contain of two properties:

[
    { 
    "field_id": 645900, 
    "field_value": "GudHub" 
    },
    { 
    "field_id": 648741, 
    "field_value": "27823.2987934" 
    }
]
