Leaderboards using Dataverse + portal lists

Loading

Building a leaderboard is an excellent way to incentivize users and engage them with a competitive or performance-based experience. Whether it’s for a game, a training program, or any other metric, Dataverse combined with Power Pages (formerly Power Apps Portals) allows you to create dynamic, real-time leaderboards for your users.

Below is a step-by-step guide to creating a leaderboard using Dataverse and Power Pages:


Key Features of the Leaderboard System

  1. Data Storage: Store leaderboard data (user scores, rankings) in Dataverse.
  2. Real-Time Updates: Display real-time updates to the leaderboard on the portal.
  3. Filtering and Sorting: Enable sorting of the leaderboard based on different criteria (e.g., score, ranking).
  4. User-Specific Views: Show users their own ranking and details in the leaderboard.
  5. Dynamic Display: Allow for visual customization of the leaderboard in Power Pages (e.g., table or chart).

Step-by-Step Guide to Creating a Leaderboard System

Step 1: Set Up a Dataverse Table for Storing Leaderboard Data

Before you can display any leaderboard, you need to store the scores and rankings in Dataverse.

  1. Go to Power AppsDataverseTables.
  2. Create a New Table for the leaderboard, for example, Leaderboard Data.
    • Add the following columns:
      • User (Lookup to the Users table or a text field if you are using external IDs).
      • Score (Number or Decimal type, depending on the metric).
      • Rank (Number type).
      • Date Achieved (Date or Date/Time type, used for showing when the score was achieved).
      • Other Metadata (Any additional details you want to capture, like course name or competition).
  3. After creating the table, ensure that the Rank field is updated programmatically either by a Power Automate flow or on data entry to maintain a correct ranking order based on scores.

Step 2: Create a Power Automate Flow for Updating Rankings

In many cases, the rank of a user will change frequently. This is especially true in scenarios where scores are updated in real-time or periodically. A Power Automate flow can be used to automatically recalculate ranks whenever a new score is added or an existing score is updated.

  1. Create a New Flow:
    • Trigger: The flow should be triggered when a new record is created or an existing record is updated in the Leaderboard Data table.
    • Action: Sort all leaderboard entries by the Score field in descending order. After sorting, update the Rank field for each user according to their position in the sorted list.
    Example of actions:
    • Use List Rows to get all leaderboard data from Dataverse.
    • Sort the results by the Score field.
    • Use an Apply to each loop to update the Rank field for each user based on their position in the sorted list.
  2. Save and Test the Flow: After creating the flow, ensure that it runs correctly by adding or modifying data in the Leaderboard Data table.

Step 3: Create a Power Pages (Portal) Page to Display the Leaderboard

After setting up the Dataverse table and automating rank updates, you need to display the leaderboard on a Power Pages site.

  1. Create a New Page in Power Pages:
    • Go to your Power Pages site and create a new page to display the leaderboard.
    • Add a Table or Gallery component to your page.
  2. Connect to Dataverse:
    • Set the data source of the table or gallery to the Leaderboard Data table in Dataverse.
    • You can filter this data to display only the top N leaderboard entries (e.g., top 10) by applying a filter or using pagination to show entries in chunks.
  3. Design the Display:
    • Include the User’s Name, Score, Rank, and Date Achieved in the gallery or table.
    • Optionally, you can use custom HTML or JavaScript to enhance the leaderboard’s appearance (e.g., color-code the top players, add a progress bar, or display profile pictures).
  4. User-Specific Views:
    • To display a user’s own ranking, you can use a Power Pages feature to show personalized data. For example, you can filter the gallery to show a single user’s entry using their User ID or Email.
  5. Real-Time Updates:
    • If you want to show real-time updates on the leaderboard, you could implement Auto Refresh or JavaScript polling to periodically check for updated data in the Leaderboard Data table and refresh the display.

Step 4: Customize the Leaderboard with Advanced Features

  1. Leaderboard Display Options:
    • Add a Top 10 leaderboard, or let users filter the leaderboard by time range (e.g., today, week, or all-time).
    • Implement pagination for displaying a large number of records.
  2. User-Specific Leaderboard:
    • To show a specific user’s rank, add a button or widget that displays their score and ranking.
    • For example, you can show a personalized message like: “You are ranked #5 in this competition!”
  3. Gamification Features:
    • Consider adding gamification elements such as badges, levels, or achievement pop-ups when users reach a specific rank.
    • Power Automate can also trigger email notifications when users achieve a certain rank or score milestone.

Step 5: Provide Filters and Sorting Options

Allow users to interact with the leaderboard by providing filtering and sorting options.

  1. Filters:
    • You can allow users to filter the leaderboard by various criteria, such as:
      • Top performers (based on score).
      • Date ranges (e.g., weekly, monthly, all-time).
      • Categories or Competitions (if applicable).
  2. Sorting:
    • Provide sorting options such as sorting by score, rank, or date.
    • Use the Dataverse query capabilities to sort and filter data before it is displayed in the portal.

Step 6: Test and Deploy

  1. Test the System:
    • Test the leaderboard system by creating new entries in the Leaderboard Data table and ensuring that the ranks are updated automatically.
    • Verify that the leaderboard displays the correct data and updates in real-time or as expected.
  2. Deploy the Leaderboard:
    • Once everything is tested and functioning, deploy the leaderboard on your Power Pages portal.
    • Monitor the leaderboard’s usage and ensure that it scales properly with the number of users.
