:Version:
    0.1.0

:Description:
    django-smartagent is an attempt to provide Django developers with a lightning fast and complete browser detection utility.

:Requirements:
    Django 1.2+

Installation
------------

Install from PyPI

::

    pip install django-smartagent

    #or

    easy_install django-smartagent

To install the app add ``smartagent`` to ``INSTALLED_APPS``

::

    INSTALLED_APPS = (
        ...
        'smartagent',
        ...
    )

Add the middleware

::

    MIDDLEWARE_CLASSES = (
        ...
        'smartagent.middleware.UserAgentDetectorMiddleware',
    )

**The middleware** is used to attach the browser characteristics to the request object, which will be accessible through **request.browser_info**

User-Agent data file
----------------------------

Django-SmartAgent comes pre-packaged with a data file containing browser info **agents_basic.pkl**. The datafile is built using various resources on the net and generated to be made compatible with the library.

You can grab the latest datafile from github https://github.com/jamespacileo/django-smartagent/downloads.

Once you grab the latest data file, place it under your project folder. To inform Django-SmartAgent of the file location you need to edit settings.py by adding:

::

    SMART_AGENT_SETTINGS = {
        'AGENT_DATASET_LOCATION': '/path/to/agent_data_set.pkl',
    }

Utilities for mobile sites
--------------------------

As it is popular for sites to have a mobile version, there are a few utility methods within the project.

A **render_to** decorator (based on django-annoying's render_to) renders a page using a desktop or mobile version of a site, depending if the user-agent is a mobile device or not.

::

    @render_to(template='desktop_template.html', mobile_template='mobile_template.html')
    def page(request):

        articles = Articles.objects.all()[:30]
        return {
            'articles': articles,
        }

which is the equivalent of:

::

    def page(request):

        articles = Articles.objects.all()[:30]
        if request.browser_info.get('ismobiledevice') and not request.session.get('force_desktop_version'):
            return render_to_response('mobile_tempalte.html', {'articles':articles, },
                                                               context_instance=RequestContext(request))
        return render_to_response('desktop_tempalte.html', {'articles':articles, },
                                                            context_instance=RequestContext(request))


Two utility URLs exist which are used to force/unforce the desktop vesion of the site. This is due to users not always wanting to view the mobile version of the site.

- **smartagent/force_desktop_version/** forces the desktop version for mobile sites

- **smartagent/unforce_desktop_version** unforces the desktop version, forcing mobile devices to view the mobile version

::

    urlpatterns = patterns('',
        ...
        (r'^smartagent/', include('smartagent.urls')))

Settings
--------

A settings variable can be added to your project settings.

The structure is the following:

::

    SMART_AGENT_SETTINGS = {
        'AGENT_DATASET_LOCATION': 'agents.pk',
    }

Usage
-----

django-smartagent adds the ``browser_info`` dictionary to the ``request`` object containing features associated with the user's browser.
