How to Loop Through a Django Backend List and Display It on the Frontend

If you've just started working with Django and are trying to display data from your backend to your frontend, it's natural to feel overwhelmed. You might encounter various issues or simply not know how to pass data from your view to your template. In this post, we'll address a common problem: how to take outputs from your Django backend (views) and display them in a frontend template.

Understanding the Problem

Let's dive into a specific example to highlight this issue. Suppose you have a Django view that retrieves collections and their respective subscription status for a user. Your current implementation looks as follows:

In this code, the app checks if each collection has a subscription and prints either "not exist" or "Ok" in the terminal. However, the challenge is – how do you take these printed outputs and display them in an HTML template? Let’s walk through the solution step by step.

The Solution

We'll modify the Django view, create a new template to display results, and update our URL configuration to load our view correctly.

Step 1: Modifying the Django View

To display the results in your template, you'll first need to collect them in a list and pass that list to the context of your template. Here's how to modify your views.py:

Step 2: Updating URL Configuration

Next, ensure that your urls.py includes the URL pattern for your new view:

Just replace the_url_where_you_want_it and the_name_you_prefer with your desired URL and name.

Step 3: Creating the Template

Finally, create an HTML template that will display the results. In your template file (your_template_name.html), you will implement the following code to loop through a_list:

Conclusion

By following these steps, you can successfully transfer the status of collections from your Django backend to your frontend. You now have a dynamic list displayed on your template, filled based on user subscriptions. This setup not only enhances user experience but also presents the information in a clear manner.

As you continue developing your Django skills, remember the key takeaway: Always collect data in views and use Django's robust templating engine to display it cleanly in HTML templates. Happy coding!
