How to Display SQLite Query Results on a Django HTML Page

Displaying data fetched from your SQLite database in a Django HTML page is a key task for any web developer using Django. If you're encountering difficulties while trying to display results from a SQLite query, you're not alone. In this guide, we’ll walk through the issue and provide a detailed solution to get your queried data displayed on your webpage effortlessly.

The Problem

In a typical Django application, you may want to display results from your SQLite database. You might have a SQLite query set in your views.py file, which you believe should work, but you're struggling to correctly render the results in your HTML template. For example, you may want to present statistics of calls received by agents in a clear, user-friendly format.

Here's a simplified version of the SQL query you're using:

The intention is to display the results like this in Python:

However, the formatting in your HTML template may not seem right. Let's resolve this issue by clearly displaying the results on the HTML page.

The Solution

Step 1: Check Your Query Logic

Firstly, ensure that your SQL query returns the expected results when tested in a Python console. From what you've shared, the query seems correct; it retrieves the AgentName alongside the corresponding call count, as needed.

Step 2: Adjust Your HTML Template

The next step involves properly iterating through the results in your detail.html file. Here, you might encounter an issue where the data fetched can appear as nested arrays. To handle this properly, we will modify our template for better readability.

Below is the corrected version of the HTML template that processes the query results and formats them appropriately:

Explanation of the Template Code

{% extends 'base.html' %}: This line ensures that we are extending a base template (helpful for consistent layout).

{% block content %}: This block will contain the main content of the page.

h1 and p tags: These provide a title and brief description of what the displayed numbers represent.

ul and li tags: We are creating an unordered list where each agent's data will be listed as list items.

{% for var in object %}: Here we iterate through the object containing our query results. Using var.0 gets the agent's name (the first item of each result) and var.1 gets the count (the second item of the result).

Step 3: Styling the Output

For better visuals, consider applying some CSS styles to format the output. This makes the data more appealing and user-friendly.

Conclusion

By following the adjustments outlined above, you can seamlessly display your SQLite query results in a Django HTML page. Remember, debugging and ensuring that your queries yield the right results is crucial, and iterating through the results correctly in your template will lead to a smooth user experience.
