Wagtail-Flags

Build Status Coverage Status

Feature flags allow you to toggle functionality based on configurable conditions.

Wagtail-Flags adds a Wagtail admin UI and Wagtail Site-based condition on top of Django-Flags. For a more complete overview of feature flags and how to use them, please see the Django-Flags documentation.

Feature flags in the Wagtail admin

Dependencies

  • Python 2.7+, 3.6+
  • Django 1.11+, 2.0+
  • Wagtail 1.13+, 2.0+
  • Django-Flags 4.2+

Installation

  1. Install Django-Flags and Wagtail-Flags:
pip install django-flags
pip install wagtail-flags
  1. Add flags and wagtailflags as installed apps in your Django settings.py:
INSTALLED_APPS = (
    ...
    'flags',
    'wagtailflags',
    ...
)

Usage

Please see the Django-Flags documentation for the most current information about defining and checking feature flags.

First, define the flag in Django settings.py:

FLAGS = {
    'MY_FLAG': []
}

Then use the flag in a Django template (mytemplate.html):

{% load feature_flags %}
{% flag_enabled 'MY_FLAG' as my_flag %}

{% if my_flag %}
  <div class="flagged-banner">
    I’m the result of a feature flag.   
  </div>
{% endif %}

Next, configure a URL for that template (urls.py):

from django.urls import path
from django.views.generic import TemplateView

urlpatterns = [
    path(r'mypage/', TemplateView.as_view(template_name='mytemplate.html')),
]

Finally, add conditions for the flag in the Wagtail admin under "Settings", "Flags", "MY_FLAG":

Creating conditions in the Wagtail admin

Extended conditions

Wagtail-Flags adds the following conditions to Django-Flags:

site

Allows a flag to be enabled for a Wagtail site that matches the hostname and port in the condition value.

FLAGS = {
    'MY_FLAG': [
        {'condition': 'site', 'value': 'staging.mysite.com'}
    ],
}
