handle queries in ListView django

by 
class ProfileList(ListView):
    template_name = 'your_template.html'
    model = Profile

    def get_queryset(self):
        query = self.request.GET.get('q')
        if query:
            object_list = self.model.objects.filter(name__icontains=query)
        else:
            object_list = self.model.objects.none()
        return object_list

Here is what the above code is Doing:
1. We created a view that inherits from ListView.
2. We defined the template_name variable to tell Django which template to use.
3. We defined the model variable to tell Django which model to query when it loads the view.
4. We created a get_queryset method to override the default queryset.
5. We created a query variable that contains the value of the q parameter in the URL.
6. If the query variable contains a value, we filter the queryset to only show objects whose name field contains the query.
7. If the query variable is empty, we return an empty queryset.
