You’re not alone! Many developers have faced this challenge, particularly when using Jinja2 with Flask to render HTML tables dynamically. The issue often arises when trying to iterate through the data and display it in an organized format. In this guide, we’ll explore how to effectively display each document in a separate row of an HTML table using Jinja2. Let’s dive into the solution step by step! The Problem The goal is to display multiple rows of data extracted from a MongoDB collection called shopdata. Your current approach is correctly fetching the data but results in all URL names displaying in a single row. Here is what your current table rendering code looks like: Your Current Jinja2 Code [[See Video to Reveal this Text or Code Snippet]] The above code loops through shopdata but renders all URL names within a single <td> element, leading to cluttered and hard-to-read output. The Solution To resolve this issue and display each url_name in its own row, we need to slightly adjust the Jinja2 loop. The key is to create a new <tr> for each iteration of the loop. Here’s how to do that: Updated Jinja2 Loop Replace your current loop with the following code: [[See Video to Reveal this Text or Code Snippet]] Explanation of Changes Removed the Colon: Notice that we removed the colon (:) after shopdata in the for statement. This is crucial because it prevents creating a single cell for all URLs. New Table Row for Each Item: By moving <tr> inside the loop, each url_name is placed in its own table row. This makes your table organized and easy to read. Benefits of This Approach Clean Presentation: Each URL will now appear in its own row, making it easier for users to identify items at a glance. Scalability: As your MongoDB collection grows, this method will dynamically adjust to display each new entry automatically. Flexibility: You can easily modify this structure for additional columns or data types simply by adding more <td> elements within the same <tr> tags. Conclusion Displaying documents from a MongoDB collection in a structured table using Jinja2 does not have to be complex. By correctly formatting your Jinja2 loop, you can achieve elegant and dynamic tables that keep your data organized and accessible.
