Can Django capture and store the name of the active user's logged-in browser in the database?

In Django, we already have session details stored in django_session and last_login in the auth_user table. However, I am interested in storing the browser name when a user logs in using their browser in the database.

Currently, I can retrieve the browser name from the active browser on the frontend page using JavaScript, but I want to save this information in the database.

I hope to achieve saving the active browser name in the database as the output.

Below is the snippet of my JavaScript code:

<html>
<body>
<div id="demo"></div>
<script>
    let browserName = "";
    if(navigator.vendor.match(/google/i)) {
        browserName = 'Browser Name: Google Chrome';
    }
    else if(navigator.vendor.match(/apple/i)) {
        browserName = 'Browser Name: Apple Safari';
    }
    else if(navigator.userAgent.match(/firefox\//i)) {
        browserName = 'Browser Name: Mozilla Firefox';
    }
    else if(navigator.userAgent.match(/edge\//i)) {
        browserName = 'Browser Name: Microsoft Edge';
    }
    else if(navigator.userAgent.match(/trident\//i)) {
        browserName = 'Browser Name: Internet Explorer';
    }
    else
    {
        browserName = navigator.userAgent + "\n" + navigator.vendor;
    }
</script>
    <h2><script type="text/javascript">document.write(browserName)</script></h2>
</body>
</html>

To easily extract and parse the user agent information, you can utilize

request.META.get('HTTP_USER_AGENT', '')
. For seamless parsing of this data, refer to https://pypi.org/project/user-agents/.

Referencing the documentation example (ua_string represents the result of the request statement):

from user_agents import parse

# Example of iPhone's user agent string
ua_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'
user_agent = parse(ua_string)

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

# Obtaining operating system properties
user_agent.os  # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
user_agent.os.family  # returns 'iOS'
user_agent.os.version  # returns (5, 1)
user_agent.os.version_string  # returns '5.1'

# Checking device properties
user_agent.device  # returns Device(family=u'iPhone', brand=u'Apple', model=u'iPhone')
user_agent.device.family  # returns 'iPhone'
user_agent.device.brand # returns 'Apple'
user_agent.device.model # returns 'iPhone'

# Displaying a formatted string version
str(user_agent) # returns "iPhone / iOS 5.1 / Mobile Safari 5.1"

Answer №2

To retrieve the user agent, simply use

request.META.get('HTTP_USER_AGENT', '')
. Implementing a middleware will allow you to store this information.

Alternatively,

You can also consider utilizing a package that includes Geo IP functionality to save user agent data:
