Django User Agents
==================

A django package that allows easy identification of visitor's browser, OS and device information,
including whether the visitor uses a mobile phone, tablet or a touch capable device. Under the hood,
it uses `user-agents <https://github.com/selwin/python-user-agents>`_.


Installation
============

1. Install ``django-user-agents``, you'll have to make sure that `user-agents`_ is installed first::

pip install pyyaml ua-parser user-agents
pip install django-user-agents

2. Configure ``settings.py``:

.. code-block:: python

INSTALLED_APPS = (
# Other apps...
'django_user_agents',
)

# Cache backend is optional, but recommended to speed up user agent parsing
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '127.0.0.1:11211',
}
}

# Name of cache backend to cache user agents. If it not specified default
# cache alias will be used. Set to `None` to disable caching.
USER_AGENTS_CACHE = 'default'
Usage
=====

Middleware
----------

Add ``UserAgentMiddleware`` in ``settings.py``:

.. code-block:: python

MIDDLEWARE_CLASSES = (
# other middlewares...
'django_user_agents.middleware.UserAgentMiddleware',
)

A ``user_agent`` attribute will now be added to ``request``, which you can use
in ``views.py``:

.. code-block:: python

def my_view(request):

# Let's assume that the visitor uses an iPhone...
request.user_agent.is_mobile # returns True
request.user_agent.is_tablet # returns False
request.user_agent.is_touch_capable # returns True
request.user_agent.is_pc # returns False
request.user_agent.is_bot # returns False

# Accessing user agent's browser attributes
request.user_agent.browser # returns Browser(family=u'Mobile Safari', version=(5, 1), version_string='5.1')
request.user_agent.browser.family # returns 'Mobile Safari'
request.user_agent.browser.version # returns (5, 1)
request.user_agent.browser.version_string # returns '5.1'

# Operating System properties
request.user_agent.os # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
request.user_agent.os.family # returns 'iOS'
request.user_agent.os.version # returns (5, 1)
request.user_agent.os.version_string # returns '5.1'

# Device properties
request.user_agent.device # returns Device(family='iPhone')
request.user_agent.device.family # returns 'iPhone'

If you have ``django.core.context_processors.request`` enabled, ``user_agent``
will also be available in template through ``request``::

{% if request.user_agent.is_mobile %}
Do stuff here...
{% endif %}


View Usage
----------

``django-user_agents`` comes with ``get_user_agent`` which takes a single
``request`` argument and returns a ``UserAgent`` instance. Example usage:

.. code-block:: python

from django_user_agents.utils import get_user_agent

def my_view(request):
user_agent = get_user_agent(request)
if user_agent.is_mobile:
# Do stuff here...
elif user_agent.is_tablet:
# Do other stuff...


Template Usage
--------------

``django-user_agents`` comes with a few template filters:

* ``is_mobile``
* ``is_tablet``
* ``is_touch_capable``
* ``is_pc``
* ``is_bot``

You can use all of these like any other django template filters::

{% load user_agents %}

{% if request|is_mobile %}
Mobile device stuff...
{% endif %}

{% if request|is_tablet %}
Tablet stuff...
{% endif %}

{% if request|is_pc %}
PC stuff...
{% endif %}

{% if request|is_touch_capable %}
Touch capable device stuff...
{% endif %}

{% if request|is_bot %}
Bot stuff...
{% endif %}
