How to Use Candy Translation to Return Data from Django to JavaScript

If you're developing a Django web application and want to incorporate multiple languages for your user interface, handling translations smoothly is vital. One common question developers face is how to translate data returned from Django's controllers.py to JavaScript. This post delves into two effective methods using the Candy Translation library to achieve that.

Understanding the Problem

You have a Django view that returns a JSON response containing translated messages. However, you need to ensure that when your JavaScript code receives this data, it correctly utilizes the translations based on the user's language preference. Here’s a brief overview of the Django view you may be working with:

In this example, the function attempts to translate a message using candy.translated. Now, let's dive into the solutions.

Solution: Using Candy Translation

In this approach, we will use Snake case styling to define a function call based on the language selected. Below are the steps and code you will need to implement this option:

Step 1: Update the views.py

You will define a function that returns JSON data with the translated message.
