Format numbers in django templates

📝🤔 transforming numbers using filters in Django templates...

Oh hi there! 👋 Are you struggling to format numbers in your Django templates? I totally get it! It seems like a simple task, but can be quite confusing trying to figure out which filter to use. But fret not, my friend! In this post, I'll guide you through the process of formatting numbers like a pro. Let's dive in! 🏊‍♂️

So, you want to format those numbers? Let's start with some examples to understand the desired outcome:

1     => 1
12    => 12
123   => 123
1234  => 1,234
12345 => 12,345

Makes sense? Excellent. Now, let me show you two different approaches you can take to achieve this.

Option 1: Using Django's intcomma filter

Django comes with a built-in filter called intcomma that adds commas to numbers. It's perfect for our use case! Here's how you can utilize it:

<!-- your_template.html -->

{% load humanize %}

<p>The formatted number is: {{ your_number|intcomma }}</p>

All you need to do is load the humanize template tag library, and then you can apply the intcomma filter to your number. Easy-peasy, right? 😉

Option 2: Using Python's locale module

If you prefer a more generic Python solution, you can handle the formatting directly in your model using the locale module. Here's how:

import locale
from django.db import models

class YourModel(models.Model):
    # your other fields
    
    @property
    def formatted_number(self):
        locale.setlocale(locale.LC_ALL, '')  # Use the system's default locale
        return locale.format_string("%d", self.your_number, grouping=True)

In this approach, we import the locale module and use the setlocale function to set the system's default locale. Then, in the property formatted_number, we use the format_string method to format the number with commas.

To display the formatted number in your template, simply access the formatted_number property of your model instance:

<!-- your_template.html -->

<p>The formatted number is: {{ your_model_instance.formatted_number }}</p>
