Retrieve Linked Items From Earlier In The Workflow

Ever found yourself deep in a workflow, scratching your head over how to piece together data from different nodes? You’re not alone. In the world of workflow management, retrieving linked items from earlier steps isn’t just a neat trick; it’s essential for maintaining data integrity and accuracy. So, let’s dive into the nitty-gritty of how you can leverage this powerful feature to streamline your processes and keep your data on point.

Why Retrieving Linked Items Matters

Every item in a node’s input data links back to the items used in previous nodes to generate it. This linkage is crucial, especially if you need to retrieve linked items from further back than the immediate previous node. It’s like having a breadcrumb trail that leads you straight to the source of your data. Here’s why it’s a game-changer:

• Maintains Data Integrity: By accessing linked items, you ensure that the data you’re working with is accurate and up-to-date.
• Enhances Workflow Efficiency: No more jumping through hoops to gather data from different nodes. Everything you need is right at your fingertips.
• Facilitates Data Restoration: Ever accidentally lost a piece of crucial data? Retrieving linked items can help you restore it without breaking a sweat.

How to Access Linked Items

Wondering how to actually retrieve those linked items from earlier in your workflow? It’s simpler than you might think. Use the command (node-name).itemMatching(currentNodeinputIndex) to access the linked items you need. Let’s break this down:

• Node Name: This is the name of the node from which you want to retrieve the data.
• Current Node Input Index: This refers to the specific item within the current node’s input data that you’re interested in.

By combining these elements, you can pinpoint exactly which linked item you need to access. It’s like having a superpower that lets you navigate your workflow with precision and ease.

Real-World Example: Customer Data Management

Let’s walk through a practical example to see how this works in action. Imagine you’re managing customer data through a series of nodes:

1. Customer Datastore Node: This node generates example data, including customer details like id, name, email, notes, country, and creation date.
2. Edit Fields Node: Here, the data is simplified to only include the customer’s name.
3. Code Node: This node restores the email address to the correct person using data from the Customer Datastore node.

In this scenario, the Code node uses JavaScript and Python scripts to match and restore email addresses to the corresponding names. The JavaScript script iterates through the input data and assigns the email from the Customer Datastore node to the restoreEmail field. The Python script does the same, ensuring that each customer’s email is accurately restored.

Code Examples for Email Restoration

Let’s take a closer look at the scripts used in the Code node:

JavaScript Example:

for (let item of $input.all()) {
    const customerData = item.linkedItem('Customer Datastore');
    item.restoreEmail = customerData.email;
    yield item;
}

Python Example:

for item in input.all():
    customer_data = item.linked_item('Customer Datastore')
    item['restoreEmail'] = customer_data['email']
    yield item

These scripts demonstrate how you can iterate through the input data and assign the email from the Customer Datastore node to the restoreEmail field, ensuring that each customer’s email is accurately restored.
