How to Fix Raw Data Display in Laravel DataTables with POST Method

If you're working on a Laravel project and utilizing DataTables to display your data, you might encounter an issue where the output shows raw data in JSON format rather than rendering a clean, organized table. This common problem often arises when using the POST method for fetching records, especially when dates are dynamically selected by the user. In this blog, we'll go through a step-by-step approach to resolve this issue, ensuring your audit trails report displays data correctly.

Understanding the Issue

You have a scenario where users can select a date range to view audit trails. Upon submitting their selection, the expected outcome is a well-formatted DataTable. Instead, you may see output that looks something like this:

This raw data indicates that while the server is sending back the results correctly, the DataTable is not set up properly to render these results visually in the browser.

Step-by-Step Solution to Display Data Tables Correctly

Step 1: Update the Controller

First, we need to modify the way your controller fetches and returns the data. Instead of directly returning the view, you'll want to establish a dedicated route for fetching data and handle it separately:

Step 2: Create a New Route for Fetching Data

You’ll need to establish a new route that the DataTables JavaScript can request data from. Here's how your function to retrieve data should look:

Step 3: Modify the JavaScript to Fetch and Render Data

In the blade file where you want to display the DataTable, ensure your JavaScript code is set up to fetch the data correctly:

Final Thoughts

By following these steps, you should be able to resolve the issue of raw data being displayed instead of a formatted DataTable when using the POST method in your Laravel application. Ensure that the routes are correctly set and the AJAX parameters are correctly formed to include necessary data like dates and CSRF tokens.

If you encounter any further issues, revisit these steps, and remember to check the network requests in your browser's developer tools to ensure that your data is being properly fetched and formatted.

With these changes, your audit trails report should now display beautifully in a structured table format, making it easy for users to review their audit data.
