How to get workitem description using Polarion Velocity script in Workitem Properties sidebar and then stored that to variable

by

Summary

The problem revolves around fetching a Polarion work item description and sending it to another API using a POST request within the Workitem Properties sidebar of a Polarion document. The current workaround involves rendering the description in a hidden div, extracting the text using JavaScript, and then sending it as input to the POST API.

Root Cause

The root cause of this issue is the lack of a direct method to access the work item description in Polarion Velocity scripts within the Workitem Properties sidebar. The current implementation requires a workaround due to this limitation. Key causes include:

  • Limited API access: The Polarion API may not provide a straightforward way to access work item descriptions.
  • Rendering requirements: The description needs to be rendered in a specific context to be accessible.

Why This Happens in Real Systems

This issue occurs in real systems due to:

  • Complexity of integration: Integrating different systems and APIs can lead to workarounds due to incompatibilities or missing features.
  • Security restrictions: Certain data, like work item descriptions, might be restricted for direct access due to security or privacy concerns.
  • Legacy system limitations: Older systems might not have the necessary APIs or functionalities to support direct access to certain data.

Real-World Impact

The real-world impact of this issue includes:

  • Increased development time: Workarounds can be time-consuming to implement and maintain.
  • Potential for errors: Indirect methods of accessing data can introduce errors or inconsistencies.
  • Performance overhead: Rendering and extracting data can add to the performance overhead of the application.

Example or Code

// Render description in a hidden div
var descriptionDiv = $wi.fields.description.render().htmlFor().forFrame();

// Extract the text using JavaScript innerText or textContent
var descriptionText = descriptionDiv.innerText || descriptionDiv.textContent;

// Send as input to post API
fetch('https://example.com/api', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ description: descriptionText })
});

How Senior Engineers Fix It

Senior engineers address this issue by:

  • Evaluating the API: They thoroughly review the Polarion API documentation to ensure no direct method is available.
  • Optimizing workarounds: They refine the workaround to be more efficient and reliable.
  • Requesting API enhancements: If necessary, they request enhancements to the Polarion API to support direct access to work item descriptions.

Why Juniors Miss It

Junior engineers might miss the optimal solution due to:

  • Lack of experience: They may not have encountered similar issues before.
  • Insufficient knowledge of the API: They might not fully understand the capabilities and limitations of the Polarion API.
  • Overlooking documentation: They could overlook crucial details in the documentation that might provide a more direct solution.
