by Alex Johnson 45 views

Introduction

This article addresses a critical issue within the DLT-Africa-Hub talent platform: the proper display of the 'Accept Offer' button in the chat interface after a graduate uploads their signed contract. Currently, there are inconsistencies in the button's appearance, potentially disrupting the offer acceptance workflow. This comprehensive guide outlines the problem, acceptance criteria, technical details, and priority, ensuring a seamless experience for both graduates and companies.

Problem Description

After a graduate uploads a signed offer document, an 'Accept Offer' button should promptly appear in the chat or message interface. However, the button may not be displaying as expected, or its placement within the user interface flow might be suboptimal. This discrepancy can lead to confusion and delays in the hiring process. The goal is to ensure that the button is clearly visible and functional at the correct stage of the offer process.

Acceptance Criteria

To resolve this issue effectively, we need to meet the following acceptance criteria:

  • Visibility After Upload: Following the upload of the signed offer document by the graduate, the 'Accept Offer' button must be immediately visible within the chat interface.
  • Clear Accessibility: The button should be designed to be easily noticeable and accessible, ensuring a smooth user experience.
  • Conditional Display Logic: The button should only be displayed under specific conditions:
    • The offer status must be 'signed', indicating that the signed document has been uploaded.
    • The offer must not have been accepted yet.
    • The offer must not have been rejected.
  • Functional Click Action: Clicking the 'Accept Offer' button must initiate the offer acceptance flow seamlessly.
  • State Change After Acceptance: After the offer is accepted, the button should either disappear or change its state to reflect the acceptance, preventing accidental re-acceptance.
  • Company-Side Status Update: The company's interface must reflect a "hired" status upon the graduate's acceptance of the offer.
  • Notification System: A notification should be sent to the company when the offer is accepted, keeping them informed of the progress.

Technical Details

Resolving this issue involves modifications across both the frontend and backend of the application. Here are the specific technical details:

Files to Modify

The following files require modifications to implement the fix:

  • frontend/src/pages/Messages.tsx: This file likely handles the main messaging interface and needs to be updated to check the offer status and render the button.
  • frontend/src/components/message/ChatModal.tsx: If the chat interface is within a modal, this file needs modification to display the 'Accept Offer' button.
  • frontend/src/components/message/MessageBubble.tsx (if separate component): If message bubbles are used, this component might need changes to incorporate the button near the signed document message.
  • backend/controllers/offer.controller.ts: This file manages offer status logic and needs verification to ensure correct status updates.

Offer Status Flow

Understanding the offer status flow is crucial for implementing the fix. The flow is as follows:

  1. Company accepts the application, leading to the creation of an offer with the status 'sent'. This indicates the offer has been sent to the graduate.
  2. The graduate downloads the offer document for review.
  3. The graduate uploads the signed document, which should trigger an update in the offer status to 'signed'. This is the critical point where the 'Accept Offer' button should appear.
  4. The graduate clicks the 'Accept Offer' button, initiating the final acceptance step.
  5. Upon clicking the button, the offer status should change to 'accepted', and the application status should be updated to 'hired', reflecting the completion of the hiring process.

UI Implementation

The user interface implementation requires careful consideration to ensure a seamless user experience. The following steps should be taken:

  • Offer Status Check: Within the message or chat component, the offer status needs to be checked dynamically.
  • Conditional Rendering: The 'Accept Offer' button should be conditionally rendered based on the offer status. Specifically, it should only appear when offer.status === 'signed'. This ensures the button is displayed at the correct time.
  • Prominent Button Styling: The button should be styled prominently, using a primary style to make it easily noticeable. This helps guide the user to the next step in the process.
  • Placement Considerations: The placement of the button is crucial. It should be placed near the signed document message or as a sticky action button to ensure it's easily accessible. Options include:
    • Adjacent to the message containing the signed document.
    • As a sticky button at the bottom of the chat window.
    • Within a dedicated action bar in the chat interface.

Backend Verification

Backend verification is essential to ensure the correct offer status updates and API functionality. The following points should be verified:

  • POST /api/graduates/offers/:offerId/upload-signed Endpoint: Ensure this endpoint correctly updates the offer status to 'signed' when a signed document is uploaded. This is a critical step in triggering the display of the 'Accept Offer' button.
  • POST /api/graduates/offers/:offerId/accept Endpoint: Verify that this endpoint functions correctly, updating the offer status to 'accepted' and the application status to 'hired' when the button is clicked. This completes the offer acceptance process.
  • API Response Integrity: Check that the offer status is included in the API responses for messages and chat. This ensures the frontend has the necessary information to conditionally render the button.

Priority

This issue is considered High priority. The correct display and functionality of the 'Accept Offer' button are critical for the offer acceptance workflow. Any disruption in this process can lead to significant delays and a negative experience for both graduates and companies. Addressing this issue promptly is essential for maintaining the efficiency and reliability of the platform.

Steps to Implement the Fix

To effectively implement the fix, follow these detailed steps:

  1. Backend Modifications ( backend/controllers/offer.controller.ts ):

    • Verify Status Update on Upload:
      • Open backend/controllers/offer.controller.ts.
      • Locate the function that handles the POST /api/graduates/offers/:offerId/upload-signed endpoint.
      • Ensure that the function correctly updates the offer status to 'signed' upon successful document upload.
      • Add detailed logging to this function to track status updates and any potential errors.
    • Verify Accept Offer Function:
      • Locate the function that handles the POST /api/graduates/offers/:offerId/accept endpoint.
      • Ensure that this function updates the offer status to 'accepted' and the application status to 'hired' correctly.
      • Add checks to ensure the offer status is 'signed' before allowing acceptance.
      • Implement robust error handling to prevent issues during the acceptance process.
    • Include Offer Status in API Responses:
      • Review the API responses for chat and message retrieval.
      • Ensure the offer status is included in these responses so the frontend can use it for conditional rendering.
      • Add tests to verify the presence and accuracy of the offer status in the responses.

  2. Frontend Modifications:

    • Modify frontend/src/pages/Messages.tsx:
      • Open frontend/src/pages/Messages.tsx.
      • Locate the component responsible for displaying the chat messages.
