How to Retrieve GET Request Values in Django?

Retrieving GET Request Values in Django

When defining regular expressions to extract parameters from URLs according to the Django tutorial, it's common to encounter an empty QueryDict object in HttpRequest.GET. Here's how to access URL parameters through HttpRequest without relying on libraries.

Using HttpRequest.GET.get()

To retrieve a GET parameter named 'q' from the URL domain/search/?q=haha:

request.GET.get('q', 'default')

The 'default' parameter specifies the default value if 'q' is not found.

Accessing Parameters in URLConf

Alternatively, if you configure your URLConf to use regular expressions, the captured parameter values are passed as arguments (or named arguments) to the associated view function. For example:

(r'^user/(?P<username>\w{0,50})/$', views.profile_page,),

In your views.py:

def profile_page(request, username):
    # Rest of the view function code
