How to get parent id of steps?

[lechuhuuha]

Hi,
I want to get the parent id of each step in the sequence. Like in this example sequence :

{
  "properties": {},
  "sequence": [
    {
      "id": "3e3c74a32774273fa5fbbe9ee2467be0",
      "componentType": "largeTask",
      "type": "welcome-new-subscriber",
      "name": "Welcome new subscriber",
      "properties": {
        "draggable": false,
        "deletable": true,
        "type": "trigger"
      }
    },
    {
      "id": "28429992da9bc6f5902a440b69fe1743",
      "componentType": "switch",
      "type": "if",
      "name": "Open email ?",
      "branches": {
        "yes": [
          {
            "id": "bd10bcc08104adec84b821dca3697e9b",
            "componentType": "largeTask",
            "type": "add-tag",
            "name": "Add tag",
            "properties": {
              "draggable": true,
              "deletable": true,
              "type": "action"
            }
          }
        ],
        "no": []
      },
      "properties": {
        "draggable": true,
        "type": "condition"
      }
    }
  ]
}

is there any built in function to get the parent id and convert the json into this

{
  "properties": {},
  "sequence": [
    {
      "id": "3e3c74a32774273fa5fbbe9ee2467be0",
      "componentType": "largeTask",
      "type": "welcome-new-subscriber",
      "name": "Welcome new subscriber",
      "properties": {
        "draggable": false,
        "deletable": true,
        "type": "trigger"
      },
      "child" : "28429992da9bc6f5902a440b69fe1743"
    },
    {
      "id": "28429992da9bc6f5902a440b69fe1743",
      "componentType": "switch",
      "type": "if",
      "name": "Open email ?",
      "branches": {
        "yes": [
          {
            "id": "bd10bcc08104adec84b821dca3697e9b",
            "componentType": "largeTask",
            "type": "add-tag",
            "name": "Add tag",
            "properties": {
              "draggable": true,
              "deletable": true,
              "type": "action"
            }
          }
        ],
        "no": []
      },
      "properties": {
        "draggable": true,
        "type": "condition"
      },
      "child" : null
    }
  ]
}

have the properties child corresponding for each step
thanks

Check the getStepParents method of the Designer class.

const step: Step = ...;
const parents = designer.getStepParents(step);
const parent = parents[parents.length - 1];

This method returns a path to a passed step. To get parent you need to read one before last item.

BTW: your suggestion would cause that the model would contain data redundancy. What is completely wrong. Now the model contains all information what you need. You can easily get an access to previous/next/parent/child step, but it requires a definition search.

@lechuhuuha is the problem solved?

@lechuhuuha is the problem solved?

Thanks
i just loop in the sequence and get the next index of step then its work perfect

Here is the code

designer = sequentialWorkflowDesigner.Designer.create(placeholder, startDefinition, configuration);
designer.onDefinitionChanged.subscribe(newDefinition => {
	refreshValidationStatus();
	if (!newDefinition && !newDefinition.sequence) {
		return;
	}

	const modifiedArray = [];
	processBranches(newDefinition.sequence, modifiedArray);

	console.clear();
	console.log(JSON.stringify(modifiedArray, null, 2));
	// console.log('the definition has changed', newDefinition.sequence);
});

function processBranches(branches, modifiedArray) {
	branches.forEach((element, index) => {
		const modifiedElement = { ...element };
		const childIndex = `${index + 1}`;

		if (branches[childIndex]) {
			modifiedElement.child = branches[childIndex].id;
		}

		modifiedArray.push(modifiedElement);

		if (modifiedElement.componentType === 'switch') {
			const yesBranch = modifiedElement.branches.yes;
			const noBranch = modifiedElement.branches.no;

			if (yesBranch.length > 0) {
				processBranches(yesBranch, modifiedArray);
			}
			if (noBranch.length > 0) {
				processBranches(noBranch, modifiedArray);
			}
		}
	});
}
