Warning

This app is known to be not complaint with the United Kingdom PECR/GDPR. It is your responsibility to find out whether django-cookie-law meets the specific local legal requirements.

Contributions and comments are welcome using Github at: http://github.com/TyMaszWeb/django-cookie-law

Please note that django-cookie-law requires:

• Django >= 1.8
• django-classy-tags >= 0.3.0

Installation

1. pip install django-cookie-law

2. Add 'cookielaw' to INSTALLED_APPS

3. Run collectstatic (Django 1.3+) or copy the statics to your media directory

4. Add cookielaw/js/cookielaw.js to the markup directly or via your asset manager such as django-pipeline or django-compressor

5. If you're using Django > 1.8, enable 'django.core.context_processors.request' in your TEMPLATES['OPTIONS'] setting, eg.:

   TEMPLATES = [
       {
           'BACKEND': 'django.template.backends.django.DjangoTemplates',
           'DIRS': [],
           'APP_DIRS': True,
           'OPTIONS': {
               'context_processors': [
                   'django.template.context_processors.debug',
                   'django.core.context_processors.i18n',
                   'django.core.context_processors.media',
                   'django.template.context_processors.request',
                   'django.contrib.auth.context_processors.auth',
                   'django.core.context_processors.static',
                   'django.core.context_processors.tz',
                   'django.contrib.messages.context_processors.messages',
               ],
           },
       },
   ]
   

If you're using an older version of Django (< 1.8) then you'll want to change the TEMPLATE_CONTEXT_PROCESSORS setting, eg.:

TEMPLATE_CONTEXT_PROCESSORS = (
        'django.contrib.auth.context_processors.auth',
        'django.core.context_processors.debug',
        'django.core.context_processors.i18n',
        'django.core.context_processors.media',
        'django.core.context_processors.request',
        'django.core.context_processors.static',
        'django.core.context_processors.tz',
        'django.contrib.messages.context_processors.messages'
    )

Note

N.b. versions below 1.8 are not officially supported.

Note

If you don't have this setting defined, just add it to your settings module.

1. {% load cookielaw_tags %} and add {% cookielaw_banner %} template tag where you want to display the cookielaw banner. Best place for this is your 'base' template, so you will have the cookie banner on every page of your website.

Configuration

If you want to use our default template, add cookielaw/css/cookielaw.css to the markup and you should see the cookie law banner at the top of the page until you dismiss it with the button in the top-right. This CSS is Twitter Bootstrap compatible, but chances are, you'll like to adjust it anyway.

To change the markup, just add a template named cookielaw/banner.html and make sure it is loaded before the default template (for example put the django.template.loaders.filesystem.Loader before django.template.loaders.app_directories.Loader and add your new template to any of the TEMPLATE_DIRS).

To change the CSS, just write your own rules and don't include the default stylesheet.

If you want your visitors to be able to reject the cookies, you should setup cookielaw context processor by adding it to TEMPLATE_CONTEXT_PROCESSORS like this:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'cookielaw.context_processors.cookielaw'
)

That will add cookielaw context variable to the template context. That variable is a dict with 3 keys: notset, accepted and rejected, each with true or false value.

Instead of default banner.html template, use rejectable.html one which shows an example of how to reject the cookies (of course, you may change the template to suit your own needs, just take care that you have <div id="CookielawBanner"> container.

In your templates, you can choose to display the banner only for new visitors (case when cookie is not set):

{% load cookielaw_tags %}
{% if cookielaw.notset %}{% rejectable_cookielaw_banner %}{% endif %}

Of course, you may use {% cookielaw_banner %} as well.

Once the visitors accepts or rejects the cookies, you may choose to load or not load the analytics trackers:

{% if cookielaw.accepted %}
    ... the code to load tracker ...
{% endif %}
