Detect mobile devices with Django and Python 3

I am struggling to find an easy way to detect if the request comes from a mobile device in my Django views.

I am trying to implement something like this:

#views.py

def myfunction(request):

    ...
    if request.mobile:
        is_mobile = True
    else:
        is_mobile = False

    context = {
        ... ,
        'is_mobile': is_mobile,
    }
    return render(request, 'mytemplate.html', context)

And in mytemplate.html:

{% if is_mobile %}    
    show something
{% else %}
    show something else
{% endif %}

Everywhere I checked (for instance here or here), minidetector is recommended. I have installed different versions: pip install minidetector, pip install minidetector2, as well as directly a couple of github repositories, but none of them are compatible with Python 3.

So here my question: Is there any version/fork of minidetector that is compatible with Python 3? If not, what are the alternatives?

Django User Agents package is compatible with Python 3.

Follow the installation instructions in the link provided above and then you can use it as follows:

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'

The usage in template is as follows:

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

However, note that the middleware class has changed in Django 1.10. So if you are using Django 1.10 +, you will have to modify the middleware class definition in this Package as given in this GitHub issue tracker page.
