django-whiff

django-whiff is a simple Django template tag that combines the functionality of the with and if tags, inspired by the Python walrus operator (:=). It allows you to assign a variable and immediately check if it is truthy, rendering content if it is.

Example

{% load whiff %}

  {% whiff current_user as user %}
    <h1>Welcome back, {{ user.first_name }} {{ user.last_name }}!</h1>
    <p>Your last login was on {{ user.last_login|date:"F j, Y, g:i a" }}.</p>

      <h2>Your Profile</h2>
      <ul>
        <li>Email:  {{ user.email }}</li>
        <li>Joined: {{ user.date_joined|date:"F j, Y" }}</li>
        <li>Bio:    {{ user.bio }}</li>
      </ul>
  {% endwhiff %}

Features

• Combines with and if in a single template tag.
• Simplifies template logic by reducing the need for nested tags.
• Easy to use and integrate into existing Django projects.

Caveats

• Not a great contender to replace multiple pipes or conditions in an existing template tag

Installation

You can install django-whiff via pip:

pip install django-whiff

Usage

Once installed, add django_whiff to your INSTALLED_APPS in your Django settings:

INSTALLED_APPS = [
    ...
    'django_whiff',
    ...
]

Note the underscore, not hyphen.

How It Works

• The whiff tag assigns the value of some_obj to obj.
• If some_obj is truthy, the content inside the whiff block is rendered.
• If some_obj is falsey, nothing is rendered.

Tests

python -m unittest discover -s tests
