What is new in Django 5.0?

The latest Django release (as of December 4, 2023) is here, and it's filled with features that are making waves in the web development community. Let's dive into what Django 5.0 brings to the table, with examples to get you excited:

1. Facet Filters in Admin: Imagine you're filtering a list of users in the admin. Now, Django 5.0 shows you how many users fall into each filter category right on the dashboard. Handy for quick insights! ??
2. Simplified Template Rendering: Before, rendering a form field involved multiple lines of template code. Now, just use {{ form.name.as_field_group }} and voilà - your form field, complete with label, widget, and help text, is rendered in one line. Clean and efficient! ??Example:

<form>
  ...
  <div>
    {{ form.name.as_field_group }}
    <div class="row">
      <div class="col">{{ form.email.as_field_group }}</div>
      <div class="col">{{ form.password.as_field_group }}</div>
    </div>
  </div>
  ...
</form>
        

1. Database-Computed Default Values: Set a default age for a new user right in your database. For instance, age = models.IntegerField(db_default=18) automatically sets the age to 18 if not provided. ??
2. Database Generated Model Field: Create a model for a square with an area that's always calculated from its side. Just define area = models.GeneratedField(expression=F("side") * F("side")), and the area updates automatically whenever the side changes. Magic! ??
3. More Flexible Field Choices: Define choices in a more readable and maintainable way. For example, use a dictionary for SPORT_CHOICES, and assign it directly to sport = models.CharField(..., choices=SPORT_CHOICES). It's as simple as it sounds. ??
4. Python Compatibility Boost: With support for Python 3.10 to 3.12, your Django projects can now leverage the latest and greatest features of Python, ensuring your code stays cutting-edge. ??

Django 5.0 is more than just an upgrade; it's a leap forward in making web development more intuitive and efficient. Whether you're a seasoned Django developer or new to the framework, these features are set to enhance your coding experience.
